What Is a Leave of Absence?

Types, paid vs unpaid, the legal rules, and how a small business handles a leave request

Sooner or later, someone on your team will need to step away from work for a while: a surgery, a new baby, an aging parent, a call to military service, or a personal crisis that cannot wait. What they are asking for is a leave of absence, and some of those requests carry legal obligations while others do not.

This guide explains what a leave of absence is, then gives you the framework to handle one: how leave differs from paid time off, which requests you must grant, whether the time is paid, the types you will meet, and the federal laws behind them. It is written for the owner who is the HR department.

That small-business lens is deliberate. Almost every guide on this topic assumes you have specialists to handle leave, and you may not. I built FirstHR so a small team can store its leave policy, collect e-signed acknowledgments, and keep employee records and a self-service portal in one place, because a mishandled request is exactly the kind of avoidable problem that catches small employers. This is general information, not legal advice, and leave laws vary by state.

TL;DR
A leave of absence is approved, extended time away from work during which the employee stays employed, unlike routine PTO. It may be mandatory under the FMLA, ADA, or USERRA, or voluntary under your own policy, and paid or unpaid. The FMLA gives 12 unpaid, job-protected weeks at employers with 50 or more employees; USERRA applies at any size.

Leave of Absence Definition

A leave of absence is an approved period during which an employee is away from work for an extended time while remaining employed. It covers significant reasons that ordinary time off does not: a serious health condition, family care, military service, or a major personal matter. Length depends on the reason and the law.

Definition
Leave of Absence (LOA)
A leave of absence is an authorized period of extended time away from work during which the employment relationship continues. It is distinct from resignation or termination because the employee remains employed and is generally expected to return. A leave of absence may be mandatory (legally required, such as FMLA or military leave) or voluntary (granted at the employer's discretion), and paid or unpaid, depending on the reason, applicable law, and company policy.

The defining feature is that employment continues throughout. Unlike quitting or being let go, a leave of absence keeps the person on your payroll records as an employee, often with their job and benefits protected, and with an expectation that they will return.

That continuity is what separates a leave from a separation, and it is why leave carries obligations that a simple absence never triggers: job protection while the person is out, benefits that keep running, and a role to come back to.

What LOA Means

LOA stands for leave of absence. It is the status code an HR or payroll system attaches to an employee who is away on approved extended leave, and it turns up on timesheets, in benefits records, and in the shorthand of anyone who has spent time around HR paperwork.

At work, saying someone is on LOA means exactly what this guide describes: approved, extended, employment continues, a return expected. The phrase LOA leave is redundant and people write it anyway, so read it as the same thing rather than as a separate category of time off.

The abbreviation takes prefixes. PLOA is a personal leave of absence, the discretionary kind covered further down. Some systems use MLOA for a medical leave of absence. A personal LOA and a medical LOA run on completely different rules, which is why the prefix is the part worth reading.

AbbreviationWhat it meansWhere you see it
LOALeave of absenceHRIS status, timesheets, benefits records
PLOAPersonal leave of absence, granted at your discretionLeave policies and request forms
MLOAMedical leave of absence for the employee's own health conditionMedical leave paperwork and disability claims
FMLAFamily and Medical Leave Act, one specific federal lawProtected leave at employers with 50 or more employees
LOA, outside HRLetter of authorization or letter of agencyVendor and carrier paperwork, nothing to do with employment

That last row is worth a glance. In business generally, those three letters usually mean a letter of authorization, a document that lets one company act for another. If an LOA arrives from a vendor rather than from an employee, it is almost certainly something to sign, not a request for time away.

Leave of Absence vs PTO

The most common point of confusion is the difference between a leave of absence and paid time off (PTO), and clearing it up first makes everything else easier. Both involve time away from work, but they serve different purposes and follow different rules. PTO is for short, routine, planned absences; a leave of absence is for longer, more significant time away.

FeaturePTOLeave of absence
Typical lengthHours to a few daysDays to several months
ReasonVacation, a sick day, personal errandsSerious illness, family care, military, major personal need
PayAlmost always paid from an accrued balanceMay be paid or unpaid
ProcessQuick request, employee discretionFormal request, often documentation and approval
Legal protectionGenerally noneSometimes legally protected (FMLA, ADA, USERRA)

These are different tools for different situations, and treating a leave of absence like a long stretch of PTO is a mistake. A leave often involves a formal request, medical or legal documentation, potential job protection, and pay and benefit decisions that a vacation day never triggers.

Recognizing that a request is really a leave of absence, not extended PTO, is the first step to handling it correctly. That recognition changes what you are legally required to do, which is why it belongs at the front of the process rather than halfway through it.

Leave of Absence vs FMLA

A leave of absence is the umbrella term for any approved extended absence. The FMLA is one specific federal law that makes certain leaves of absence job-protected. Every FMLA leave is a leave of absence, and most leaves of absence are not FMLA leave.

That distinction decides who makes the call. If a request qualifies under the FMLA and you are a covered employer, you grant it. If it does not qualify, you are back in policy territory, where your written rules and how consistently you apply them settle the answer instead.

Leave of absenceFMLA leave
What it isA category of extended absenceA federal entitlement created by statute
Which employersAny employer that chooses to grant onePrivate employers with 50 or more employees
Employee eligibilityWhatever your policy says12 months of service, 1,250 hours in the 12 months before leave, and a worksite with 50 employees within 75 miles
LengthSet by policy, by law, or by the accommodationUp to 12 weeks, or 26 for military caregiver leave
Job protectionOnly where a law provides itYes, the same or an equivalent position
Can you decline it?Yes, for voluntary leaveNo, if the employee qualifies

For a private employer under 50 employees, having no FMLA obligations is not the same as having none at all. What you grant is a leave of absence shaped by your own policy, by the Americans with Disabilities Act (ADA) once you reach 15 employees, by the military leave law USERRA, and by whatever your state requires.

Mandatory vs Voluntary Leave

The single most important distinction for an employer is whether a leave is mandatory or voluntary, because it determines whether you have a choice. Mandatory leave is required by law: if an employee qualifies, you must grant it. Voluntary leave is offered at your discretion: you decide whether to approve it. Confusing the two is where small employers get into trouble.

Mandatory leave (must grant if eligible)
FMLA leave for eligible employees at covered employers.
Military leave and reemployment under USERRA.
Leave as a reasonable accommodation under the ADA.
Jury duty leave and various state and local leave mandates.
Voluntary leave (employer discretion)
Extended personal leave not covered by a specific law.
Sabbaticals and educational leave.
Bereavement leave in states that do not mandate it.
Additional medical leave beyond what law requires.

Mandatory leave comes from specific laws, each with its own rules about who is covered and what you must do. If an employee meets the criteria for FMLA, USERRA, or an ADA accommodation, granting the leave is not optional, and denying it can expose you to legal liability.

Voluntary leave is a policy choice. You can offer generous personal or bereavement leave to stay competitive, or decline a request that no law requires you to grant, as long as you apply your policy consistently and without discrimination among people in the same situation.

A sabbatical is the cleanest illustration of that second column. Nothing obliges you to offer one, so its length, eligibility, and pay are entirely yours to define, and the only real constraint is whether you can spare the person for that long.

For a small business, the practical rule is to ask whether any law requires the leave before treating it as a discretionary decision. Many owners instinctively treat every request as theirs to approve or deny, which is fine for voluntary leave and a serious error for protected leave.

Knowing which employment laws apply to you, which turns largely on your size and location, is what lets you sort mandatory from voluntary correctly. The legal framework section below walks through each of the three federal laws and the state layer on top of them.

Watch the word mandatory, because it gets used for two opposite situations. A mandatory unpaid leave of absence usually means leave you are required to grant. Protected leave is normally unpaid, so those two words end up side by side constantly. The FMLA is the clearest case: required, and not paid.

The other meaning is leave you impose, which is a furlough rather than a leave request. Under the salary basis rule, you may not deduct from the salary of an exempt employee (one paid a salary and not owed overtime) for time when work is not available and the employee is ready, willing, and able to work.

The exception is a full workweek. Exempt employees need not be paid for any workweek in which they perform no work, which is why furloughs are usually structured in whole weeks. Docking salary for scattered days off, in a week that includes some work, is what breaks the salary basis rule.

A leave of absence can be either paid or unpaid, and much protected leave is unpaid. Legal protection usually guarantees the job, not the paycheck, which surprises employers and employees alike. The FMLA shows it plainly: 12 weeks of job protection, and no requirement to pay for any of it.

Whether a particular leave is paid depends on the type of leave, the law that applies, your written policy, and whether the employee uses accrued paid time off to cover it. Those four inputs can point in different directions on the same leave, which is what makes the question hard.

Often unpaid
Federal FMLA leave is unpaid, though employees can use accrued PTO.
Most extended personal leave not covered by a specific law.
Additional medical leave beyond paid benefits.
May be paid or carry pay rules
State paid family and medical leave in a growing number of states.
Jury duty and certain civic leave, with pay rules varying by state.
Employer-chosen paid leave, such as paid parental or bereavement leave.

The federal baseline, then, is up to 12 weeks of unpaid, job-protected FMLA leave, though the employee can still draw a paycheck from their own accrued time. Under 29 CFR 825.207, an employee may choose to substitute accrued paid leave, and if they do not choose it, the employer may require it.

State programs sit on top of that baseline. Where a state paid family and medical leave program already pays benefits, it replaces part of an employee's wages, so leave that federal law leaves unpaid is partly paid there.

The number of states with these programs keeps growing. Fourteen states and the District of Columbia have enacted paid family and medical leave laws. The U.S. Department of Labor Women's Bureau counts 13 states and DC, and Virginia became the 14th when it enacted its program in April 2026, with benefits starting by December 1, 2028.

The practical approach is to say in your policy which leaves are paid, which are unpaid time off, and how accrued PTO interacts with each one. Employees carry a lot of anxiety about pay during a leave, and a written answer removes most of it.

Clarity is worth more than generosity here. A sentence saying "this leave is unpaid, but you may use accrued PTO" or "this leave is covered by the state program" prevents the confusion that turns into a dispute, even when the answer is that the leave itself is unpaid.

Types of Leave of Absence

Leave of absence is an umbrella term covering several distinct types, each with its own typical reason, legal treatment, and pay rules. Knowing the main types helps you recognize what an employee is really requesting and what obligations come with it. These are the categories a small business is most likely to encounter.

Medical leaveTime off for the employee's own serious health condition, surgery, or recovery. Often protected under the FMLA at covered employers and sometimes tied to disability benefits.
Family leaveLeave to care for a family member with a serious health condition, or to bond with a new child. Frequently FMLA-protected and, in some states, paid through a state program.
Personal leaveDiscretionary time off for personal reasons that do not fit other categories. Usually voluntary and unpaid, granted at the employer's discretion.
Military leaveLeave for military service or related obligations, protected under federal USERRA, which guarantees reemployment rights for service members.
Jury duty and civic leaveTime off to serve on a jury or fulfill certain civic obligations. Job protection is required by law, though pay rules vary by state.
Bereavement leaveTime off after the death of a family member. Usually voluntary and set by employer policy, though a few states have begun to mandate it.

The reason for a leave largely determines the rules that apply to it, whether it is paid, and whether you must grant it. That is why each type gets its own look below, in the depth a small business needs to handle it correctly.

Medical leave

Medical leave is time off for an employee's own serious health condition: surgery and recovery, a serious illness, a chronic condition that flares up, or a hospitalization. It is one of the most common and most consequential types, because it is frequently protected by law and often involves coordinating several benefits at once.

The legal picture is layered. At a covered employer, the employee's own serious health condition qualifies for FMLA job protection. If the condition also rises to the level of a disability, the ADA may require leave as a reasonable accommodation, sometimes beyond what the FMLA provides.

Pay is a separate question. FMLA leave is unpaid, but the employee may be covered by short-term disability insurance, a state paid leave program, or accrued paid time off during the same period. Those sources run in sequence more often than people expect.

A single medical leave can therefore involve FMLA protection, ADA obligations, and more than one source of pay. That combination is why medical leave is the type employers most often mishandle, and why it pays to map all three layers before the leave starts.

For a small business, identify medical leave early, check which protections apply at your size, and coordinate the pay sources deliberately. Even if you are too small for the FMLA, you may owe leave under the ADA at 15 or more employees, and a state program may provide pay at any size.

Family and parental leave

Family leave covers time off to care for a family member with a serious health condition, and parental leave covers bonding with a new child by birth, adoption, or foster placement. Both are among the most frequently requested leaves, and both sit at the center of the federal and state framework.

Bonding leave is gender-neutral, which employers get wrong often enough to be worth stating plainly. The FMLA entitles an eligible father to the same 12 weeks as an eligible mother, and a bonding-leave policy that offers less to one than the other invites a discrimination claim.

At a covered employer, caring for a spouse, child, or parent with a serious health condition, and bonding with a new child, both qualify for up to 12 weeks of FMLA job protection. Pay is where the states have moved faster than federal law.

FMLA leave itself is unpaid, but a growing number of states run paid family and medical leave programs that replace part of an employee's wages during exactly this kind of leave, and they often cover employers far smaller than the FMLA does.

Parental and family leave is also an area where being small does not mean being exempt. State paid leave programs frequently apply to employers of any size, so even a very small business may need to participate, withhold contributions as a payroll deduction, and grant the leave the program covers.

Personal leave

Personal leave is discretionary time off for personal reasons that do not fit the other categories: a family matter, a personal project, an extended trip, or a life event that needs more time than paid time off covers. It is usually voluntary, and typically unpaid unless the employee uses accrued time or you choose to pay.

Because personal leave is discretionary, your own policy governs it almost entirely. That gives a small business flexibility, and it creates a fairness obligation: if you grant extended personal leave to one employee, apply the same standard to the next person in a comparable situation.

A written policy does most of that work. Stating when personal leave is available, how long it can run, and how it is requested prevents most of the disputes this category generates, and it gives you something to point at when you decline a request.

Personal leave often overlaps with other types at the edges. An employee might request personal leave for a reason that, examined closely, qualifies as protected medical or family leave. Check whether the underlying reason triggers legal protection before treating a request as purely discretionary, because misclassifying protected leave as personal is a common and risky mistake.

Military leave

Military leave covers time off for military service, whether active duty, training, or related obligations, and it is unique because its core protections reach every employer. Under 20 CFR 1002.34, USERRA applies to all public and private employers in the United States, regardless of size.

The entitlement itself is reemployment. An employee who leaves to perform military service is generally entitled to return to the same or a comparable position, with the benefits and seniority they would have held had they never left, provided they gave notice and returned within the required window.

This universal coverage is the key point for a small business. Medical and family leave protections depend on your size; USERRA's reemployment rights do not, so a business with a handful of employees must honor them in full, and there is no small-employer exemption to fall back on.

The FMLA adds a military family layer at covered employers. It provides qualifying exigency leave to handle a family member's deployment, and up to 26 weeks in a single 12-month period to care for a covered servicemember with a serious injury or illness.

In practice, treat any military-service leave request as legally protected from the start, document the leave and the return carefully, and reinstate the employee properly when they come back.

Jury duty and civic leave

Jury duty leave, and related civic leave such as time to vote or respond to a subpoena, is time off to meet a legal obligation. Under 28 U.S.C. 1875, no employer may discharge, threaten, intimidate, or coerce a permanent employee because of jury service in a federal court.

State law covers state and local jury service, and it is where the pay rules live. Job protection is close to universal; whether the time is paid is not, so a business with employees in more than one state can owe different things in each.

Some states require pay for part of jury service. New York Judiciary Law 519, for example, bars an employer with more than 10 employees from withholding the first $72 of a juror-employee's daily wages during the first three days of service. Others require only that the job be protected while the employee serves unpaid.

Voting leave follows the same pattern. State laws differ on whether time off to vote must be paid, how much is required, and what notice the employee owes, so the answer changes with the state rather than with your policy.

For most small businesses, jury and civic leave is straightforward to administer: protect the job, follow your state's pay rules, and ask for documentation such as the jury summons. The main pitfall is treating it as optional or penalizing an employee for serving, which can violate the law.

Bereavement leave

Bereavement leave is time off after the death of a family member. It has historically been a voluntary benefit set by employer policy, typically a few days for a close relative, though a small but growing number of states now mandate it.

California is the clearest example. Government Code section 12945.7 requires employers with five or more employees to allow up to five days of bereavement leave for a family member's death, completed within three months of the death. The days need not be consecutive.

Because bereavement leave is mostly discretionary, the decisions are policy ones: how many days you offer, which relationships count as immediate family, and whether the time is paid. Employers increasingly take a broader view, extending the benefit to a wider circle of relationships and to situations like miscarriage.

A written bereavement policy is what removes the ambiguity. Specifying the days offered and the relationships covered means neither the employee nor the manager has to negotiate at a moment when neither of them wants to. It is a low-cost benefit that signals real support.

Where a state does mandate bereavement leave, the requirement sits on top of your voluntary policy, so check every state where you have employees. Even without a mandate, this is a leave type where a clear, generous policy costs little and is remembered for a long time.

Leave Requests Are Rising
According to leave-management survey data reported by SHRM (March 2025), 57% of employers reported an increase in employee leave requests in 2024, and 53% of those employers saw the volume rise by 21% or more. The most common reasons for those requests were recovering from injury or illness (57%), managing mental health challenges (47%), caring for an aging parent (37%), and parental leave (34%). For a small business, leave is a regular event worth a process, not a rare edge case to improvise around.

These types overlap in practice. A single leave can be both medical and FMLA-protected, or both family leave and paid through a state program, so the work is to identify the reason and then check which laws and policies attach to it.

Medical and family leave are the most likely to be legally protected and the most consequential to get wrong. Personal and bereavement leave are more often voluntary and governed by your own policy. The next section covers the laws that turn some of these types into obligations.

Several federal laws turn certain leave requests into legal obligations, and knowing them is what lets you tell mandatory leave from voluntary. Each law has its own scope, and for a small business the difference that matters most is size: some apply only above a headcount threshold, while others apply to nearly everyone.

The Family and Medical Leave Act is the big one. It gives eligible employees up to 12 weeks of unpaid, job-protected leave in a 12-month period for a serious health condition, to care for a family member, or to bond with a new child, and up to 26 weeks for military caregiver leave.

Coverage is where small employers are affected. The FMLA reaches a private employer only at 50 or more employees, under the headcount test set out in the FMLA mechanics below, so many small businesses fall outside the FMLA entirely.

Two other federal laws reach much further. The Americans with Disabilities Act requires employers with 15 or more employees to provide reasonable accommodations to qualified individuals with disabilities, and leave can be one of them, so an employer too small for the FMLA may still owe leave under the ADA.

The Uniformed Services Employment and Reemployment Rights Act, or USERRA, protects the leave and reemployment rights of employees who serve in the military, and it applies regardless of employer size. Even a business with two employees has military-leave obligations of its own.

Small Size Does Not Mean No Obligations
It is a common and costly misconception that a small business has no leave obligations. While the FMLA only applies at 50 or more employees, the ADA reaches employers with 15 or more, and USERRA and many state and local leave laws apply regardless of size. That means a business with a handful of employees can still be legally required to grant certain leave, such as military leave or leave as a disability accommodation. Never assume being small exempts you from all leave law. Confirm which federal, state, and local rules apply to you, because the mix depends on your size and location. This is general information, not legal advice.

On top of federal law sits a growing layer of state and local leave law, which varies widely and changes often. Many states mandate paid sick leave, a growing number run paid family and medical leave programs, and some have their own family-leave laws.

Those state family-leave laws often reach employers the FMLA never touches, including businesses well under 50 employees. Because the state layer can impose obligations federal law does not, you have to check the laws of every state where you have employees.

These three federal laws and the state layer each work differently, so it pays to understand the mechanics of each one rather than treat them as interchangeable. Start with the FMLA, because the other two are easiest to understand by how they differ from it.

How the FMLA works

The FMLA is the foundation of protected leave in the United States, and its mechanics reward careful attention. Under 29 CFR 825.104, a private employer is covered once it has 50 or more employees for each working day in 20 or more calendar workweeks of the current or preceding year.

Public agencies are covered whatever their headcount, as are public and private elementary and secondary schools. Employee eligibility is a separate test, and both have to be met, which is why not every employee at a covered employer qualifies in practice.

To be eligible, an employee must have worked for the employer for at least 12 months, have logged at least 1,250 hours in the 12 months before the leave, and work at a site where the employer has at least 50 employees within 75 miles. That last test is the one people mistake for the coverage rule.

When both tests are met, the FMLA provides up to 12 weeks of unpaid, job-protected leave in a 12-month period: for a serious health condition, to care for a family member with one, to bond with a new child, or for qualifying needs arising from a family member's military deployment.

A separate provision runs longer. Up to 26 weeks in a single 12-month period are available to care for a covered servicemember with a serious injury or illness. In every case the leave is job-protected: the employee returns to the same or an equivalent position, with equivalent pay, benefits, and terms.

Two features often surprise employers. First, FMLA leave can be taken intermittently, in separate blocks or on a reduced schedule, when it is medically necessary. Second, group health benefits must be maintained during the leave on the same terms as if the employee were working, so you keep paying the employer share of premiums.

Notice, documentation, and job-restoration duties come with all of it, so a covered employer needs a deliberate process rather than case-by-case judgment. A small business growing toward 50 employees should watch for the moment it crosses the line and becomes subject to the act.

How the ADA applies to leave

The ADA enters the leave picture differently, and it catches small employers off guard because it reaches businesses too small for the FMLA. It applies at 15 or more employees and requires reasonable accommodations for qualified individuals with disabilities, unless the accommodation would cause undue hardship, meaning significant difficulty or expense. Leave can be one of them.

The central mechanic is the interactive process. When an employee with a disability needs an accommodation, the employer is expected to engage in a good-faith, back-and-forth discussion to identify a reasonable one, and to document what was discussed at each step.

Leave itself can be the accommodation. If a period of leave would let the employee recover and return, that leave may be what the ADA requires, even after FMLA leave is exhausted or where the FMLA never applied. There is no fixed number of weeks.

The limit is indefinite leave. EEOC guidance states that indefinite leave constitutes an undue hardship and does not have to be provided, while additional finite leave beyond a policy maximum may be required when the employer cannot show hardship. For a small business with 15 or more employees, that is the practical boundary.

Because the analysis turns on the facts and the interactive process has to be genuine, documenting the conversation is what protects the business later. For close calls, an employment attorney is worth the hour. Keep the file open, too: the ADA's duties often continue after the employee returns.

How USERRA protects military leave

USERRA is distinctive because it applies to essentially all employers regardless of size, giving it the broadest reach of the three federal laws. It protects employees who leave a civilian job to perform military service, guaranteeing them the right to reemployment when they return.

That reemployment right comes with conditions, such as giving notice, not exceeding cumulative service limits, and returning within the required timeframe. When they are met, USERRA's escalator principle makes the right strong: a returning servicemember is generally entitled not just to the old job but to the position, seniority, pay, and benefits they would have attained had they remained continuously employed.

The law also bars discrimination because of military service and provides for continuation of health coverage during it. These protections apply whether the employer has five employees or five thousand, which is why military leave is never a discretionary decision for a small business.

The practical duties are to grant the leave, treat the employee as continuously employed for seniority, and reinstate them to the position they would have reached. Because the escalator principle makes that more involved than handing back the old role, keep records of the employee's role and trajectory before the leave.

State and local leave laws

The fastest-changing part of the leave landscape is the state and local layer, which increasingly imposes obligations that federal law does not, and often on much smaller employers. Three components matter most to a small business, and each one moves on its own schedule.

Paid family and medical leave comes first. A growing number of states run programs that replace part of an employee's wages during family and medical leave, funded through payroll contributions, and many of them apply to employers of any size, unlike the FMLA.

Paid sick leave is second. Many states and cities now require a set amount of paid sick time that employees can use for their own health needs or a family member's, with accrual rules and carryover caps written into each law.

State family-leave laws are third. Some mirror the FMLA, some expand it, and some cover employers well below the 50-employee federal threshold or define family more broadly. California's CFRA (the California Family Rights Act) is the standard example. It applies to California employers the federal law leaves alone.

The complication is that these laws vary enormously by state and locality and change frequently, so a business with employees in several states can face several leave regimes at once. A leave that is unpaid and unprotected under federal law may be paid and protected under a particular state's program.

Size thresholds, covered reasons, and pay rules all differ between them. The only reliable approach is to confirm the current requirements for every state and city where you have employees rather than assuming the federal rules settle the matter on their own.

How Long a Leave of Absence Lasts

There is no single answer: a leave of absence runs anywhere from a few days to several months, and the length comes from the reason, the law that applies, and your own policy. The FMLA caps protected leave at 12 weeks in a 12-month period, or 26 weeks for military caregiver leave. Nothing else carries a fixed federal ceiling.

Short term, temporary, and extended leave

These three phrases describe one thing at different lengths, and none of them is a legal category. A short term leave of absence usually means days to a few weeks: a procedure and the recovery after it, a family emergency, a bereavement that needs more than the standard few days.

A temporary leave of absence is the same idea framed by intent rather than by length. The employee is coming back, the role is being held, and the arrangement has an end point. Every leave of absence is temporary by definition, and that is precisely what separates it from a resignation.

An extended leave of absence is the one that forces a decision. Once a request runs past 12 weeks, or past whatever your policy allows, you are choosing whether to hold the job open. For protected leave that choice may not be yours, since the ADA can require additional finite leave as an accommodation after the FMLA runs out.

For unprotected personal leave the choice is genuinely yours. The safeguard is applying the same standard to the next person who asks, and writing down what that standard is before the next request arrives. A written standard is far easier to prove than one you have to remember.

Continuous vs intermittent leave

A continuous leave of absence is one unbroken block: the employee stops working on a date and returns on a date. It is the default shape, the easiest to arrange coverage for, and the one most leave policies are quietly written around.

An intermittent leave of absence is the same entitlement taken in pieces: separate blocks of time, or a reduced schedule of fewer hours per day or week. Department of Labor guidance on the FMLA states that employees may take protected leave all at once or, when medically necessary, in separate blocks or by reducing the hours they work.

Continuous leave
One unbroken block with a start date and an end date.
Coverage gets arranged once and stays in place.
Tracking is a start, an end, and a return.
The shape most leave policies assume by default.
Intermittent or reduced schedule leave
Separate blocks of time, or fewer hours per day or week.
Coverage has to flex, often at short notice.
Tracking runs in increments against the entitlement.
Common for chronic conditions and periodic treatment.

Bonding leave is the exception worth memorizing. Under 29 CFR 825.120, an eligible employee may use intermittent or reduced-schedule leave to be with a healthy newborn only if the employer agrees, and 29 CFR 825.121 sets the same condition after a placement for adoption or foster care.

Leave for a serious health condition works the other way. No employer agreement is needed there; the test is whether the leave is medically necessary.

Intermittent leave is also where tracking stops being optional. Under 29 CFR 825.205, you must account for it in an increment no greater than the shortest period you use for any other kind of leave, and never greater than one hour. An afternoon here and two hours there have to land accurately against the entitlement.

Leave of Absence for Small Businesses

If you are a small business owner who is also the HR department, leave presents a specific challenge that big-company guides ignore: not just the legal side, but the practical problem of covering the work when one person out of a small team is gone for weeks. Handling leave well as a small employer means addressing both halves.

On the legal side, the priority is knowing your obligations, which depend on your size. Under 15 employees, you are below the ADA threshold and well under the FMLA, so your mandatory obligations are mostly USERRA plus any state or local law.

From 15 to 49 employees, the ADA applies, so leave as a disability accommodation becomes a real obligation. At 50 or more, the FMLA arrives with its full 12-week protection. Knowing which band you are in tells you most of what you must do.

The practical side is coverage. When someone on a small team is out for weeks, the work still has to happen, and improvising each time is stressful and inconsistent. The businesses that handle this well plan ahead instead of reacting.

Those businesses cross-train employees so more than one person can cover key tasks, document core processes as standard operating procedures so a fill-in can follow them, and keep a clear record of who is out and when. That is operational resilience more than law, and it is where a small team feels a leave most.

What worked for me
The first extended leave request I got, from a five-person team, threw me, not because of the law but because I had no idea how we would cover the work. I said yes, then scrambled. What I learned is that the scramble is avoidable. After that, we did two simple things: cross-trained so at least two people understood each critical task, and wrote down the core processes that lived only in someone's head. The next leave was a non-event operationally. For a small business, the legal question is only half of it. The other half is making sure one person being out does not break the whole operation, and a little preparation solves it.

How to Handle a Leave Request

When a leave request lands on your desk, a simple, consistent process protects both the employee and the business. You do not need an HR department to handle leave well; you need a clear sequence you follow every time. These six steps are that sequence.

1
Get the request in writingAsk the employee to submit the reason, expected start date, and expected duration in writing, so you have a clear record and can assess what applies.
2
Identify the type and whether it is protectedDetermine the reason and check whether FMLA, ADA, USERRA, or a state or local law makes the leave mandatory, which tells you whether you have a choice.
3
Determine pay and benefitsDecide, per your policy and the law, whether the leave is paid or unpaid, how accrued PTO applies, and what happens to benefits during the leave.
4
Confirm the decision in writingGive the employee a written response covering the leave dates, pay and benefits, job protection, and expectations for staying in touch and returning.
5
Plan coverage and track the leaveArrange how the work will be covered, and keep an accurate record of the leave dates and status so nothing falls through the cracks.
6
Manage the returnConfirm the return date, reinstate the employee appropriately, and handle any adjustments, especially important for legally protected leave with reinstatement rights.

The thread through all six steps is documentation and consistency. Getting the request in writing, confirming the decision with something like an approved leave of absence letter, and keeping a record of the leave protects you if a dispute arises.

For protected leave, that paper trail is more than good practice: it is how you demonstrate compliance. Build it into a simple repeatable process, ideally supported by a system that tracks who is out and when, and leave turns from a source of stress into a routine.

Pay and Benefits During a Leave of Absence

What happens to pay and benefits during a leave depends on the type of leave and the law that applies. Health insurance is the piece to get right first, because a mistake there creates both a compliance problem and serious hardship for the employee.

On pay, the baseline is that many leaves are unpaid unless a specific source provides income. During an unpaid leave an employee may bridge the gap with accrued paid time off, and your policy should state whether they may or must do so.

Other income sources sit behind that one. Short-term disability insurance can cover a medical leave, a state paid family and medical leave program can cover a qualifying family or medical leave, and some employers fund a paid leave benefit of their own. A single leave may draw on more than one in sequence.

Health insurance is the highest-stakes benefit question. Under 29 CFR 825.209, an employer must maintain the employee's group health coverage during FMLA leave on the same conditions as if they had kept working, so the employer share of premiums keeps flowing and the employee stays responsible for theirs.

For leaves the FMLA does not cover, continuation depends on your plan terms and your policy. If coverage does end, COBRA continuation rights may apply. Either way, confirm the answer with your plan before the leave starts rather than after a gap in coverage has already opened.

Other benefits follow your own rules. Retirement contributions, seniority accrual, and whether PTO keeps accruing during FMLA may pause or continue depending on the policy you wrote, which is a reason to write it down before anyone needs to ask.

Map the Pay and Benefits Before the Leave Starts
The cleanest way to avoid disputes is to lay out, in writing before the leave begins, exactly how pay and benefits will work: whether the leave is paid or unpaid, whether and how accrued PTO is used, what income sources apply and in what order, how health coverage continues and who pays which share, and what happens to other benefits. A one-page summary given to the employee at the start of the leave removes almost all of the anxiety and confusion this area generates, and it creates a record you can point to if questions arise later. This is general information, not legal advice.

Writing a Leave of Absence Policy

Whether or not the law requires a given leave, a written leave of absence policy turns a confusing set of rules into a predictable process for both sides. It does not need to be long. It needs to answer the questions that come up every time someone requests leave.

A solid small-business leave policy covers a short list of essentials. It defines the types of leave available, both the legally protected ones and any voluntary leave you offer, and it explains who is eligible, from what point, and how to request leave, including notice and documentation.

The rest is money and mechanics. State how each leave interacts with pay, accrued PTO, and benefits, how it coordinates with the FMLA if you are covered, and what the return-to-work process looks like, including expectations for staying in touch during a long leave.

Consistency is the point that matters most legally. A policy applied unevenly, granting one employee generous personal leave while denying a comparable request from another, invites disparate treatment claims and erodes trust. The safeguard is to write the policy clearly, apply it the same way to everyone in similar situations, and document your decisions.

Managing the Return to Work

The end of a leave is as important as its start, and it is where legally protected leave carries some of its strongest requirements. Managing the return well protects the business from reinstatement claims and helps the employee transition back smoothly, yet it is the step employers most often neglect after the leave itself is arranged.

For job-protected leave, reinstatement is the central obligation. Under 29 CFR 825.214, an employee returning from FMLA leave is entitled to the same position or an equivalent one with equivalent pay, benefits, and other terms and conditions of employment. After USERRA military leave, they are entitled to the position, seniority, and pay they would have reached.

These are legal rights rather than courtesies. Demoting a returning employee or filling the role permanently can expose the business to liability, and even for voluntary unprotected leave, a clear understanding of what position the employee comes back to prevents most disputes.

Beyond the legal duty, a thoughtful return process eases the transition. Confirming the return date in advance, ideally on a return-to-work form, updating the employee on what changed while they were out, and restoring their access and tools all help them become productive again quickly.

A medical return needs one more step. The ADA's reasonable-accommodation duties may continue after the leave ends, so an employee coming back with restrictions may be entitled to accommodations, and discussing temporary adjustments before the first day back closes the loop properly.

Common Leave of Absence Mistakes to Avoid

The same leave mistakes recur across small businesses, and most of them are avoidable once you know to watch for them. Leave law is layered and the stakes include both legal liability and employee trust, so these are the errors worth checking your own process against.

The most damaging mistake is assuming that being small means having no leave obligations. The ADA reaches employers with 15 or more employees, USERRA and many state laws apply regardless of size, and state paid leave programs frequently cover the smallest employers.

A related error is misclassifying protected leave as voluntary. Treating what is really an FMLA or ADA situation as discretionary personal leave forfeits the employee's protections and exposes the business, and it usually happens because nobody asked which law applied before answering.

Other frequent mistakes cluster around process. Failing to maintain health coverage during FMLA leave is a common and serious compliance error. Applying leave policies inconsistently, granting favors to some employees and denying comparable requests from others, invites discrimination claims. Both are avoidable with a checklist.

Neglecting reinstatement is a third process mistake. Demoting or displacing an employee returning from protected leave is a recurring problem, and so is simply failing to document requests, decisions, and the leave itself, which leaves the business unable to show compliance if challenged.

Nearly all of these trace back to two habits: not checking which laws actually apply, and not keeping clear, consistent records. That is why a deliberate process and good tracking matter as much as knowing the rules. Neither one costs anything but attention.

Key Takeaways
A leave of absence is approved, extended time away from work during which the employee remains employed and is generally expected to return.
Mandatory leave required by the FMLA, ADA, or USERRA must be granted when the employee qualifies; voluntary leave is your decision.
The FMLA covers private employers with 50 or more employees, the ADA reaches 15 or more, and USERRA applies at any size.
Much protected leave is unpaid: the FMLA guarantees the job for up to 12 weeks, not the paycheck.
During FMLA leave you must maintain the employee's group health coverage on the same conditions as if they were working.
Handle every request the same way: get it in writing, check whether it is protected, settle pay and benefits, confirm in writing, plan coverage, and manage the return.

Frequently Asked Questions

What is a leave of absence?

A leave of absence is an approved period of time an employee is allowed to be away from work, usually for an extended reason such as a serious illness, caring for a family member, military service, or a significant personal matter. Unlike regular paid time off, it typically covers longer absences and may be either paid or unpaid and either legally required or granted at the employer's discretion. The employee remains employed during the leave, and in many cases their job is protected. Most employers ask for a written request and, for medical or family reasons, supporting documentation before approving one.

What does a leave of absence mean at work?

At work, a leave of absence means an employee has formal permission to step away from their job for a set period while remaining employed. It is different from quitting or being terminated: the employment relationship continues, and the employee is generally expected to return. Depending on the reason and the law, the leave may be paid or unpaid, and the employee's job and benefits may be protected. Employers usually require a request and approval process, and often documentation, before granting one. The status also shows up in payroll and benefits records, which is why the paperwork should say what was approved and for how long.

Is a leave of absence paid or unpaid?

It can be either, and the answer comes from the type of leave rather than from the words leave of absence. Federal FMLA leave is unpaid, as is most extended personal leave, though employees can often use accrued paid time off to bridge the gap. Jury duty and military leave carry their own pay rules, which differ by state. Twelve states and the District of Columbia already pay partial wage replacement through a state paid family and medical leave program, so the same absence can be unpaid under federal law and partly paid by the state. Maryland and Virginia have enacted programs too, with benefits starting in 2028, so that map keeps changing. Your own policy decides the rest.

Does an employer have to approve a leave of absence?

It depends on whether the leave is legally protected. Some leave is mandatory: if an employee qualifies for FMLA leave, military leave under USERRA, or leave as a disability accommodation under the ADA, the employer generally must grant it. Other leave is voluntary, meaning the employer can approve or deny it at its discretion, such as extended personal leave that is not legally protected. So the answer is that some leave must be approved by law, while other leave is up to the employer. The safest habit is to ask which law applies before deciding, because misreading a protected request as a discretionary one is where the liability sits.

What is the difference between a leave of absence and PTO?

PTO, or paid time off, covers short, routine, usually paid absences like vacation or a sick day, drawn from an accrued balance and taken at the employee's discretion. A leave of absence covers longer, often extended absences for significant reasons like a serious illness or family need, may be paid or unpaid, and often involves a formal request, documentation, and sometimes legal protection. In short, PTO is for short planned time off, while a leave of absence is for longer, more significant time away. The two get tangled together in practice, because an employee on unpaid leave may use accrued PTO to keep getting paid during it.

How long can a leave of absence last?

The length varies by the type of leave and the law. Federal FMLA leave provides up to 12 weeks in a 12-month period for eligible employees at covered employers, or up to 26 weeks for certain military caregiver situations. Other leave, such as personal or extended medical leave beyond FMLA, has no fixed legal length and is set by employer policy or by what a disability accommodation reasonably requires. So a leave can range from a few days to several months depending on the reason and applicable rules. Because no federal law besides the FMLA sets a maximum, an unprotected leave lasts as long as your policy says it does.

Can you be fired while on a leave of absence?

It depends on whether the leave is legally protected. If an employee is on job-protected leave, such as FMLA or military leave, the employer generally cannot fire them because of the leave and must reinstate them afterward. For voluntary, unprotected leave, protections are weaker and depend on company policy and state law. Employers must be careful, since terminating someone on protected leave can violate federal or state law. Ending employment during a protected leave for a reason unrelated to the leave is possible but hard to defend, which is why the reason and its timing should be documented. This is general information, not legal advice, so confirm specifics for your situation.

Does a small business have to offer a leave of absence?

It depends on the law and your size. Some federal leave laws only apply above a size threshold: under the FMLA a private employer is covered only after it has had 50 or more employees for 20 or more workweeks in the current or preceding calendar year, so a smaller business has no FMLA obligation. Other rules reach much smaller employers: the ADA's reasonable accommodation duties begin at 15 employees, USERRA's military leave protections apply at any size, and state and local leave laws may apply too. So even a very small business often has some mandatory leave obligations, plus whatever voluntary leave it chooses to offer.

What happens to health insurance during a leave of absence?

It depends on the type of leave. Under the FMLA, a covered employer has to keep the employee's group health plan in place for the length of the leave, on the same terms as if they were still working: you keep paying the employer portion of the premium, and the employee keeps paying theirs. For leave the FMLA does not cover, your health plan terms and company policy decide whether coverage continues. When coverage does stop during a leave, COBRA continuation rights may let the employee keep it by paying the cost themselves. A lapse is both a compliance issue and a hardship for the person on leave, so check how your plan handles leave before one begins.

Can FMLA leave be taken a little at a time?

Yes. When it is medically necessary, an eligible employee can split FMLA leave into pieces instead of using it in one stretch. That can mean occasional absences, such as a day off for each round of treatment, or a shortened schedule in which the employee works fewer hours each day or each week. It is common for someone managing a chronic condition that flares up, or treatment that recurs on a schedule. Every piece is deducted from the employee's 12-week entitlement, so a covered employer needs an accurate running record. Under federal rules, the tracking increment can be no larger than one hour, which means a two-hour absence cannot be rounded up to half a day. However the time is split, the total stays within the FMLA entitlement for the 12-month period.

What is the difference between a leave of absence and resignation?

The key difference is that the employment relationship continues during a leave of absence but ends with a resignation. On a leave of absence, the employee remains employed, is generally expected to return, and often has their job and benefits protected. When an employee resigns, they end their employment entirely, with no expectation or right of return. This is why a leave of absence carries obligations around job protection, benefits, and reinstatement that a resignation does not. Treating a leave as if it were a resignation, by filling the role permanently or ending benefits improperly, can violate the law for protected leave.

How do I write a leave of absence policy for a small business?

Keep it short and practical, and make it answer the questions every leave request raises. List the kinds of leave you offer, separating the ones the law requires from the ones you grant voluntarily. Say who qualifies, how an employee asks for time off, how much notice you expect, and what paperwork backs up a request. Then cover the money: whether each leave is paid, when accrued PTO may or must be used, and what happens to benefits while the employee is out. If you are covered by the FMLA, explain how your policy fits alongside it, and finish with what happens when the employee comes back. Length matters far less than consistency. Put the policy in writing, walk new hires through it during onboarding so nobody is surprised later, and apply it the same way to everyone in a comparable situation, because even-handed application is the main legal safeguard.
