Military Leave of Absence: USERRA Rules for Employers
USERRA rules for a military leave of absence: notice, the five-year limit, reemployment deadlines, the escalator position, and health coverage.
The first time an employee put a set of orders on my desk, I read them twice and understood almost none of it. I knew he was a reservist. I had known since his first week. What I did not know was what I owed him, what I was allowed to ask for, or what his job was supposed to look like when he walked back in seven months later.
So I did what most owners without an HR department do. I searched, found a federal statute with an acronym that sounds like a filing cabinet, and read a summary telling me military leave is job protected. That sentence is true and close to useless. The Uniformed Services Employment and Reemployment Rights Act (USERRA) is not one rule. It is a sequence of rules, and almost every one of them turns on exactly how long the person was gone.
This guide takes you through that sequence in order, from the notice you receive to the protection that follows the person back to work.
Get the sequence right and this is a manageable leave obligation, because the statute tells you what to do at each step. Get it wrong and you are looking at a claim with no filing deadline attached to it. I build the people and records tooling for teams without a dedicated HR person at FirstHR. This is general information rather than legal advice, and a contested reemployment is worth an employment lawyer before you decide anything.
What a Military Leave of Absence Is
A military leave of absence is a job-protected absence taken by an employee performing service in the uniformed services. The controlling federal law is the Uniformed Services Employment and Reemployment Rights Act, codified at 38 U.S.C. 4301 and following, and administered by the Veterans Employment and Training Service at the Department of Labor.
Three features make this different from the leave rules most small employers already know. First, there is no headcount threshold, no hours-worked test and no tenure requirement, so a person hired on Monday who ships out on Friday is covered (20 CFR 1002.41).
Second, coverage attaches to voluntary service as well as involuntary callups. Third, the protections run in both directions: they cover the leave itself and the reemployment that follows it (DOL VETS USERRA pocket guide).
The volume of disputes is going the wrong way. According to the Government Accountability Office (GAO-26-108197, June 2026), the Department of Labor closed 5,433 USERRA complaints between fiscal 2021 and fiscal 2025, and the annual count rose every year to reach 1,380 in fiscal 2025.
About thirty percent of those complaints were closed as not substantiated. That category includes investigations where the evidence showed the employer would have taken the same action regardless of military service, which is a reminder that a documented, consistent process is most of the defense.
Who Is Covered and Which Duty Counts
Virtually every private and public employer in the United States is covered, regardless of size, and the employee side reaches further than most owners assume. Service in the uniformed services includes far more than a deployment, and the short absences are the ones that get mishandled.
| Type of duty | Covered by USERRA | What it looks like on your schedule |
|---|---|---|
| Active duty under federal orders | Yes | A deployment, a mobilization, or a recall to federal active service |
| Active duty for training and initial active duty for training | Yes | Basic training, technical school, the annual training period |
| Inactive duty training | Yes | The monthly drill weekend a reservist or Guard member works |
| Full-time National Guard duty under federal authority | Yes | Extended Guard service performed under federal orders |
| State active duty of fourteen days or more | Yes, since the 2021 amendment | A governor ordering the Guard out for a sustained state mission |
| State active duty supporting a presidential national emergency or major disaster | Yes | Guard response to a declared major disaster |
| Shorter state active duty outside those triggers | No, state law is the only protection | A brief state callout for a local emergency |
| An examination to determine fitness for duty | Yes | A medical or physical evaluation ahead of a callup |
| Funeral honors duty | Yes | An authorized honors detail, often a single day |
That state active duty line is the newest and the least known. Until January 2021 state active duty sat entirely outside the federal statute. Congress then brought qualifying state duty inside the definition of service (38 U.S.C. 4303), so the analysis now starts with the length of the callout and the type of declaration behind it rather than with a flat assumption that state service is somebody else’s problem.
The statute also prohibits making military membership, application for membership, service or an obligation to serve a motivating factor in any employment decision, and it separately protects anyone who assists an enforcement action. That makes it a retaliation statute as well as a leave statute, and a single complaint can raise both.
The Notice Your Employee Owes You
The employee, or an officer of the uniformed service, must give you advance notice of the service, and that is the entire requirement. Notice may be verbal or written, may be informal, and does not have to follow any particular format.
There is no statutory minimum notice period. The Department of Defense recommends at least thirty days ahead of departure where that is feasible, and the regulations encourage employees to give as much notice as is reasonable under the circumstances (20 CFR 1002.85). Notice is excused entirely where military necessity makes it impossible, or where giving it would be otherwise impossible or unreasonable.
What you should build instead is a receiving process. One named person takes the notice, records the date it arrived, notes the expected start and expected length, and files it where the rest of the personnel file lives. That record is what tells you, months later, which return deadline applies and how much of the five-year clock has been used. Fill this one in on the day the notice arrives, in whatever form the notice arrived.
Receiving notice does not give you control over the timing of service. You may not require the employee to schedule service around your operational needs, and the employee owes you no accommodation on the timing, frequency, or duration of it (20 CFR 1002.104). If the timing is a genuine problem, your recourse is to raise it with the appropriate military authority, not with the employee.
What you can do, and what almost every reservist will help with, is plan. Drill weekends are usually scheduled well in advance, and annual training dates are rarely a surprise to anyone except the manager who never asked.
The Five-Year Cumulative Limit and Its Exceptions
Reemployment rights run until the cumulative length of all absences for uniformed service with that employer exceeds five years. The clock is per employer, so it resets when the person changes jobs. The clock counts only the time actually spent performing non-exempt service, never the days before it starts or the return window after it ends (20 CFR 1002.100).
The exceptions are where the real answer lives. A long list of service does not count against the five years at all, and once you read the list you find that whole categories of deployment fall inside it (38 U.S.C. 4312).
Service excluded from the tally includes duty required to complete an initial period of obligated service beyond five years, service the person could not be released from through no fault of their own, and duty ordered because of a war or national emergency, in support of an operational mission or a critical mission, or as part of a National Guard callup into federal service.
Training is excluded as well. The periodic drill weekends and annual training that Guard and Reserve members must complete never count toward the five years, and neither does additional training certified as necessary for professional development or skill training, according to the Department of Labor regulations (20 CFR 1002.103).
Read together, the exclusions mean an employer counting raw months away will overstate the number whenever any of them applies. If you believe an employee is approaching the limit, that is the moment for legal advice rather than a decision, because getting it wrong ends a reemployment right and invites a claim with no filing deadline.
Pay, Status and Benefits While the Employee Is Away
During military service the employee is deemed to be on furlough or leave of absence, and is entitled to the non-seniority rights and benefits you generally provide to other employees on comparable leaves. They are not terminated, and treating them as a separation is a structural mistake that every later step inherits.
USERRA does not require you to pay wages during the service period. Two qualifications matter. Federal appellate courts have held that where an employer pays employees for comparable non-military absences such as jury duty, bereavement or sick leave, short-term military leave must be paid on the same footing, because paid leave is one of the rights and benefits comparable leaves receive.
The Third Circuit reached that conclusion in Travers v. Federal Express in August 2021, following the Seventh Circuit. Comparability is not automatic. The Department of Labor regulation says duration may be the most significant factor and also weighs the purpose of the leave and whether the employee chooses its timing (20 CFR 1002.150).
The second qualification is tax treatment for employers who do choose to pay. Differential wage payments, meaning payments covering all or part of the wages an employee would have earned while on active duty of more than thirty days, are treated as wages for income tax withholding under Internal Revenue Code section 3401(h) and are reported on Form W-2.
Differential wage payments are not wages for Social Security, Medicare, or federal unemployment tax purposes, a position the Internal Revenue Service confirmed in Revenue Ruling 2009-11. Getting that split wrong shows up in your payroll records as a reconciliation problem months later.
Continuing Health Coverage During the Leave
An employee on military leave may elect to continue employer health coverage for themselves and their dependents for up to twenty-four months, measured from the first day of the absence. The premium rules split at the thirty-day mark and the split is easy to get backwards.
For service of less than thirty-one days, you may not charge the employee more than the employee share, which in practice means coverage simply continues on the normal terms.
For longer service you may charge up to one hundred two percent of the full premium, the same arithmetic used for federal continuation coverage under the Consolidated Omnibus Budget Reconciliation Act, or COBRA (38 U.S.C. 4317).
| Length of the service period | Maximum you may charge | Duration available | On reemployment |
|---|---|---|---|
| Less than thirty-one days | No more than the employee share | The full period of the absence | Coverage was never interrupted |
| Thirty-one days or more | Up to one hundred two percent of the full premium | Up to twenty-four months from the first day of the absence | Reinstated with no waiting period and no new exclusion |
| Employee declines continuation | Nothing, coverage lapses | Not applicable | Reinstated with no waiting period and no new exclusion |
The reinstatement rule is the one that costs employers money. When coverage resumes on reemployment, you may not impose a waiting period or an exclusion that would not have applied had the person never left, and the protection extends to dependents. The only carve-out is for illnesses or injuries the Department of Veterans Affairs determines to be service-connected.
Coverage under this rule and federal continuation coverage can run alongside each other, which confuses administrators who are used to a single track. If you already handle COBRA qualifying events, treat the military leave election as a parallel process with its own maximum period rather than folding it into the same workflow.
The two tracks differ in reach and length. According to the Department of Labor, COBRA applies to group health plans of employers with twenty or more employees and runs eighteen months, with extensions for certain events, while USERRA applies regardless of employer size and runs up to twenty-four months (DOL reservist benefits FAQ).
Reemployment Deadlines by Length of Service
The return deadline scales with the length of the completed service period, and there are three tiers plus a recovery extension. Missing the deadline does not automatically end reemployment rights; it makes the absence subject to your ordinary attendance and conduct rules instead.
| Length of the service period | What the employee must do | By when | Documentation you may require |
|---|---|---|---|
| Less than thirty-one days, and fitness examinations | Report back to work | The start of the first full regularly scheduled work period on the first full calendar day after completing service, once a period allowing safe transportation home plus eight hours of rest has expired | None |
| More than thirty days but less than one hundred eighty-one days | Submit an application for reemployment, written or verbal | Within fourteen days of completing service | Proof the application was timely, the five-year limit was not exceeded, and the separation was not disqualifying |
| More than one hundred eighty days | Submit an application for reemployment, written or verbal | Within ninety days of completing service | The same documentation |
| Recovering from a service-connected illness or injury | Report or apply once recovered | Up to two years from completion of service, extended for circumstances beyond the person’s control | The same documentation |
Reemployment itself must be prompt. The regulations define that as soon as practicable and, absent unusual circumstances, require it within two weeks of the application (20 CFR 1002.181). After a drill weekend, prompt means the next regularly scheduled shift. After a multi-year deployment it may take longer, because you may need to give notice to whoever is currently holding the position.
You are not required to reemploy in three narrow situations, and you carry the burden of proving each: your circumstances changed so much that reemployment is impossible or unreasonable, helping the person qualify through training or reasonable accommodation of a service-connected disability would impose an undue hardship, or the employment the person left was brief and non-recurrent with no reasonable expectation of continuing.
A filled position never counts as changed circumstances. The Department of Labor regulations bar refusing reemployment because a replacement was hired, even when reemployment means letting the replacement go (20 CFR 1002.139). Treat a hiring freeze with the same suspicion, because the regulation’s own example of a qualifying change is an intervening reduction in force that would have included the returning employee.
The Escalator Position, Not the Old Position
The returning employee goes back into the job they would have held if their employment had not been interrupted, not the job they left. That is the escalator principle, and it is easy to miss because it sounds like a formality and is actually a pay calculation (38 U.S.C. 4313).
The standard is reasonable certainty, not possibility. Seniority accrual and shift bids awarded by seniority move the employee up the escalator too, alongside the automatic pay steps, group-wide raises and seniority-driven promotions listed above. A discretionary promotion awarded on a manager’s judgment usually does not, because nobody can say with reasonable certainty it would have gone to this person.
Service length changes what you may offer. For service of less than ninety-one days the escalator position is the requirement, with the pre-service position available only if the employee cannot qualify for the escalator role after your reasonable efforts to train them.
Longer service gives you more room. For service of more than ninety days you may offer the escalator position or a position of like seniority, status and pay whose duties the person is qualified to perform.
The qualification duty is real and it is yours. If the role changed while the person was away, if the software is new, if the certification lapsed, you owe reasonable efforts at training or retraining before you may move to a fallback position.
The qualification duty extends to reasonable accommodation where the employee returns with a service-connected disability, so this question belongs next to the general medical leave and accommodation analysis.
All of that is a paper exercise, and it is one you can finish weeks before the person walks back in. Work through it line by line, because the completed sheet is the reemployment offer.

Ryan HowardSalesUp to DateThe Discharge Protection Window After Return
A reemployed employee may not be discharged except for cause for a fixed period after the date of reemployment, and the window scales with the service that preceded it. The window is one year after service of more than one hundred eighty days, and one hundred eighty days after service of more than thirty days but less than one hundred eighty-one days (38 U.S.C. 4316).
Service of thirty days or less carries no special window, though the general prohibition on making military service a motivating factor in any employment decision continues to apply for as long as the person works for you. That prohibition has no expiry date, and the statute sets no time limit for filing a claim under it (38 U.S.C. 4327).
Inside the window, the burden of proof reverses. You must show that the discharge was reasonable under the circumstances and that the employee had notice, express or fairly implied, that the conduct in question would lead to dismissal (20 CFR 1002.248).
That reversed burden is a materially higher bar than the at-will default most small employers operate under, and it is the practical reason to run any separation in this period past counsel.
Cause can also mean a legitimate business reason unrelated to conduct, such as a genuine reduction in force that would have reached this position anyway. The evidence has to exist independently of the return, which in practice means the reorganization plan, the selection criteria and the dated decision record all need to sit in the file before the conversation happens. That is the same discipline any defensible termination requires, applied with a heavier burden.
Pension Credit and Seniority
Military service is not a break in service for pension purposes (38 U.S.C. 4318). The period counts toward eligibility, vesting and benefit accrual as though the employee had been continuously employed, and the employer is liable for funding the obligation attributable to it.
Employee contributions work on a makeup schedule. A returning employee may make up elective deferrals (the salary they choose to put into the retirement plan) or required contributions over a period equal to three times the length of the service period, capped at five years from the date of reemployment.
The employee may not contribute more than they would have been permitted to contribute had they stayed, and employer matching obligations attach to those makeup contributions when they are made rather than at the original date.
Compensation for the period is calculated at the rate the employee would have received had they not left. Where that rate is not reasonably certain, the statute directs you to use the employee’s average rate of compensation over the twelve months immediately preceding the service period.
Seniority follows the same logic across every benefit that depends on it: accrual rates that rise with tenure, vacation banding, service awards, eligibility dates in your benefits package. If the number goes up with time served, the military absence counts as time served.
State Military Leave Laws That Go Further
USERRA is a floor rather than a ceiling. The statute expressly preserves any federal or state law, contract or policy that gives a more beneficial right, and supersedes anything that reduces one (38 U.S.C. 4302). The Department of Labor notes that many states have military leave laws of their own, and the overlap is uneven enough that a single national policy will be wrong somewhere.
| What the state layer often adds | How it typically works | Why it matters to you |
|---|---|---|
| Coverage for state active duty the federal statute does not reach | Job protection for Guard members called out by a governor for shorter state missions | This is a common gap, and a federal-only policy misses it entirely |
| Protection for state defense forces and organized militia | Coverage for state units that are not part of the National Guard | Your employee may hold a status the federal definition never mentions |
| A guaranteed block of leave for training each year | An annual entitlement of paid or unpaid days for drills and annual training | A policy written only to the federal floor can under-deliver here |
| Differential pay mandates | The employer makes up the gap between military pay and civilian pay for a set period | San Francisco imposes this on private employers with one hundred or more employees, effective February 2023 |
| Leave for family members of deployed service members | Unpaid job-protected leave for a spouse, parent or other relative during deployment | The employee is not the service member, so the federal statute does not apply at all |
| Independent notice and posting duties | State-specific posters or written notices layered on the federal requirement | Add them to your notice inventory rather than assuming one poster covers everything |
San Francisco shows what the differential-pay pattern looks like in practice. Its Military Leave Pay Protection Act requires private employers with one hundred or more employees, counted regardless of location, to pay reservists who work in the city the gap between gross military pay and regular civilian pay, for up to thirty days of duty a calendar year (Ordinance No. 008-23).
Illinois is a clean example of the family-member pattern. Its Military Leave Act (820 ILCS 151), titled the Family Military Leave Act until August 2025, gives unpaid job-protected leave to a spouse, parent, child, or grandparent of someone called to service lasting more than thirty days (Illinois Attorney General).
The Illinois entitlement scales with employer size: up to fifteen days at employers with fifteen to fifty employees and up to thirty days above that. Nothing in the federal statute reaches a relative’s leave, which is why an employer relying only on USERRA reads the request as discretionary when the state has already answered it.
In practice, check the law of the state where each employee actually performs the work. For a distributed team, that is often not the state your office sits in. The same rule governs employment law for remote workers generally, and military leave is one of the places where the state layer is thickest.
Federal law also requires you to give covered employees notice of their rights, benefits and obligations, and posting the Department of Labor notice where you customarily post employee notices satisfies it (38 U.S.C. 4334). Fold it into the rest of your required employee notices rather than treating it as a one-off.
A Sample Military Leave Policy
A usable policy does five things: it states who is covered, it tells the employee how to give notice without creating a forfeiture, it explains what happens to pay and benefits, it sets out the return process, and it promises no discrimination or retaliation. Everything else is decoration.
Keep it in the handbook next to the other leave entries so a manager reading about jury duty finds this one on the same page. If you are building the whole leave section from scratch, the leave of absence policy templates give you a structure to slot this into rather than a blank document.
Two kinds of clause need to come out of an existing policy. The first conditions protected leave on advance written notice, a copy of orders, or manager approval, and the statute allows none of those conditions. The second requires the employee to exhaust paid time off before military leave begins, and forcing the use of vacation is prohibited outright.
One sentence worth adding that costs you nothing: a line saying that where state or local law provides greater rights, that law governs. It is already true, it prevents a manager from applying the federal floor in a state that sits above it, and it signals to every reader that you have actually thought about this.
The Reemployment Checklist
Reemployment is a process with a defined order, and running it in order is most of the compliance work. Each step produces a record, and the records are what an investigator asks for.
Almost all of this is record-keeping rather than judgment, so keep it in whatever system already holds your employee data instead of a manager’s inbox, and start the record on the day the notice arrives.

Frequently Asked Questions
What is a military leave of absence?
It is time away from a civilian job to perform duty in the uniformed services, with a legal right to get the job back afterward. The governing law is the Uniformed Services Employment and Reemployment Rights Act (USERRA), which reaches nearly every private and public employer in the country, whatever its size. The process runs in a fixed order: the employee gives notice, leaves, serves, and then reports back or applies for reemployment by a deadline that depends on how long the service lasted. While the employee is away, you treat them as on leave rather than separated. They keep seniority-based rights as though they had worked continuously and may choose to keep their health coverage. When they return, you must place them in the position they would have reached had the employment never been interrupted.
How long can a military leave of absence last?
The cumulative limit is five years of service with the same employer, and the count starts over when the employee changes employers. In practice the number is smaller than it sounds, because many kinds of service are excluded from it. These include service needed to finish an initial period of obligated service beyond the five years, service that continued because the person could not obtain release orders through no fault of their own, the routine drill weekends and annual training every Guard and Reserve member owes, extra training certified as necessary for professional development or skills, and duty ordered in response to a war or national emergency, to support an operational or critical mission, or to answer a National Guard callup into federal service. Many deployments therefore use up none of the five years, and counting raw calendar time can easily give the wrong answer.
Do employers have to pay employees on military leave?
Generally no. USERRA does not make you pay wages while an employee is in military service, and according to the Society for Human Resource Management’s 2026 Employee Benefits Survey, only 22 percent of organizations offer paid military leave. Two things complicate that answer. First, federal appeals courts, including the Seventh and Third Circuits, have ruled that when you pay for comparable non-military time off such as jury duty, bereavement or sick days, short-term military leave has to be paid on the same terms, since paid leave is a benefit those comparable absences receive. Second, some local rules require differential pay outright: San Francisco obliges private employers with one hundred or more employees to make up the difference between military and civilian pay, capped at thirty days of duty per calendar year. If you choose to pay differential wages during active duty of more than thirty days, they count as wages for income tax withholding and go on Form W-2, but for Social Security, Medicare and federal unemployment tax purposes they do not count as wages.
How long does an employee have to return to work after military leave?
The deadline depends on how long the service lasted. After service of less than thirty-one days, the employee simply reports back for the first full regularly scheduled work period beginning on the first full calendar day after service ends, once safe travel home and eight hours of rest have passed. After service of thirty-one to one hundred eighty days, the employee has fourteen days to submit an application for reemployment. After service of more than one hundred eighty days, the application window is ninety days. An employee recovering from an illness or injury caused by service gets up to two years, which can be extended for circumstances beyond their control. Missing a deadline does not automatically end reemployment rights. Instead, the absence is judged under your ordinary attendance and conduct rules.
What is the escalator principle under USERRA?
The escalator principle says a returning employee is placed in the job they would have reached had they never left, not simply the job they held when they went. When pay steps, seniority accrual, shift bids awarded by seniority or seniority-driven promotions moved while the employee was away, the employee moves with them. If the role changed, you owe reasonable efforts to qualify the person for it through training. After service of more than ninety days, you may instead offer a position of like seniority, status and pay. The principle works in both directions: if the department was eliminated or the whole group was laid off while the employee was gone, the employee lands where they would have landed, and you carry the burden of proving that outcome.
Can you fire an employee after they return from military leave?
Yes, but only for cause while the protection window is open, and never because of the service itself. If the employee was reemployed after service of more than one hundred eighty days, you cannot discharge them except for cause for one year from the date of reemployment. After service of thirty-one to one hundred eighty days, the same protection lasts one hundred eighty days. For shorter service no special window applies, although the ban on treating military service as a motivating factor in any employment decision continues. While a protected window is open, you have to prove that the discharge was reasonable and that the employee had notice the conduct would lead to it. A USERRA claim also has no statute of limitations.
What happens to health insurance during military leave?
The employee can elect to keep themselves and their dependents covered for up to twenty-four months, counted from the day the absence begins. What you can charge depends on the length of service. When the service lasts less than thirty-one days, the cost to the employee cannot exceed the normal employee share, so coverage effectively carries on unchanged. For longer service, you can charge as much as one hundred two percent of the full premium, which mirrors the formula used for COBRA continuation coverage. Employers usually stumble on the return. Once coverage resumes on reemployment, you cannot make the employee serve a waiting period or accept an exclusion that would not have applied if they had never left, with a narrow exception for conditions the Department of Veterans Affairs determines to be service-connected.
Does USERRA cover National Guard members called up by a governor?
Sometimes, and the rule changed in 2021. State active duty ordered under a governor’s authority was historically outside USERRA entirely, leaving state law as the only protection. Congress amended the definition of service in the uniformed services so that state active duty of fourteen days or more, or state active duty in support of a national emergency declared by the President or a major disaster declared under the Stafford Act (the federal disaster relief law), now falls inside the federal framework. Short state callouts that meet neither test remain outside it. Because many states protect Guard members on state orders under their own laws, as the Department of Labor’s USERRA regulations note, the practical answer for an employer is to check the state rule first and treat the federal one as the floor.
