On-Call Pay: How It Works and When It's Required
How on-call pay works for a small business: when the FLSA requires it, engaged to wait vs waiting to be engaged, calculation, overtime, and policy.
On-Call Pay
When the law requires you to pay for on-call time, the engaged-to-wait line that decides it, how to calculate it, and how to set a policy that keeps you out of trouble
On-call pay is one of the most confusing payroll questions for a small-business owner, and for a good reason: the honest answer to whether you have to pay for it really is that it depends. Two employees can both be on call, and one is owed money for the time while the other is not, based on a distinction that is easy to miss and expensive to get wrong.
The good news is that the distinction, once you see it, is simple. It is the first thing I would tell any founder: one question decides nearly everything. This article puts that question front and center, then works through how to calculate the pay, how it collides with overtime, and how to write a policy that keeps you out of trouble. It is written for the owner running this without an HR department.
Two threads run through all of it: what the law requires you to pay, and what you might choose to pay on top as a matter of policy. Keeping those separate is half the battle. I build FirstHR, which handles the classification records and policy documentation this depends on, and pairs with your payroll and scheduling tools. One note before we start: this is general information, not legal advice. On-call rules are fact-specific and state law varies, so confirm your situation before relying on it.
What On-Call Pay Is
On-call pay is compensation for time an employee spends available to work outside their normal shift, ready to respond if they are needed. But the term hides two different things, and separating them clears up most of the confusion.
The legal part is not optional and is governed by federal rules that this article will walk through. The policy part is entirely your choice: whether to pay a standby premium, how much, and for whom. Both get called on-call pay, which is why owners often cannot tell which one someone is asking about.
Throughout this article, when the law requires payment it is the FLSA hours-worked question, and when an employer chooses to pay it is policy. Getting the legal part right keeps you compliant; getting the policy part right keeps you competitive and fair.
The FLSA Rule
The federal rule for whether on-call time must be paid comes down to one test, set out in Department of Labor (DOL) guidance and regulations, and everything else follows from it.
This framework is not new. According to the Supreme Court in Skidmore v. Swift (1944), no principle of law precludes waiting time from also being working time, and the answer turns on the agreement between the parties, how they actually behave, and the nature of the service. The Department of Labor codified that reasoning into the two-category rule employers use today.
The crucial word is fact-specific. There is no bright-line rule that says on-call is always paid or never paid. The DOL Hours Worked Advisor says the same thing plainly: whether on-call hours are hours worked is a question of fact decided case by case, and not all on-call time is hours worked. That is exactly why the next section, the engaged-to-wait distinction, is the heart of the whole topic.
Engaged to Wait vs Waiting to Be Engaged
This distinction decides nearly every on-call pay question: engaged to wait is on-call time that counts as work and must be paid, while waiting to be engaged is time the employee can use as their own, which generally does not have to be paid. Once it clicks, the rest of the topic falls into place.
The names are old-fashioned but the idea is intuitive. Engaged to wait means the waiting is itself part of the job, because the restrictions are tight enough that the time is not really the employee's own.
The Department of Labor's own examples show it: a secretary who reads a book while waiting for dictation and a fireman who plays checkers while waiting for an alarm are both working, even during quiet stretches.
Waiting to be engaged means the employee is genuinely off, just carrying a phone, free to do whatever they like until and unless a call comes.
The reason this matters so much financially is that the same on-call shift can fall on either side depending on the details you set as the employer. Require someone to stay within five minutes of the site and answer constant calls, and you have likely created compensable time. Just ask them to keep their phone on, and you probably have not. Your policy design is what determines which side of the line the time lands on.
What Makes On-Call Time Paid
Since it is a fact-specific test, it helps to know the specific facts that push on-call time toward compensable. Courts and the Department of Labor look at a cluster of factors.
The mistake owners make is treating any one of these as a switch. It is not. A short response window on its own does not automatically create paid time if calls are rare and the employee can otherwise roam freely. Frequent calls might not be decisive if the response window is generous.
The determination is holistic: the question is always whether, taken together, the restrictions have curtailed the employee's freedom enough that the time no longer genuinely belongs to them. When you design an on-call arrangement, you are effectively dialing these factors up or down, and that is what sets your pay obligation.
Because the test is applied to one particular arrangement rather than to on-call duty in general, the answer is worth writing down for each rotation you run, at the time you set it. The sheet below walks the five factors, records where each one leans, and captures the determination and the reasoning behind it. Fill it in again whenever you tighten a response window or a radius, because that is the moment the answer can change.
Exempt vs Non-Exempt: Who This Applies To
One threshold point that determines whether any of this even applies: the FLSA on-call rules are about non-exempt employees. Exempt employees are a different story.
Non-exempt employees, generally hourly workers, are covered by the FLSA's minimum wage and overtime protections, and the entire engaged-to-wait analysis exists to determine their pay. If you have hourly staff carrying a pager or phone, this is the group the rules are built for.
Exempt employees, generally salaried workers who meet the FLSA's salary and duties tests, are exempt from those same minimum wage and overtime rules. They receive their salary regardless of hours, so the federal on-call compensability analysis does not require extra pay for their on-call time. Many employers still pay exempt staff an on-call stipend as a matter of policy and fairness, but that is a choice, not a federal obligation.
How to Calculate On-Call Pay
On-call pay is calculated in layers. Once you know the employee is non-exempt and whether the standby time is compensable, the calculation is a matter of adding the pieces in the right order.
The layering is what trips people up. A flat standby rate, the regular rate for actual work, and the overtime check are three separate calculations that all apply to the same on-call shift.
None of the three can be done from memory at the end of the month, because each one needs standby hours and call time kept apart from each other as they happen. An ordinary timesheet does not make that distinction. The log below does: one row per on-call period, the calls that came in, the time actually worked on them, and a weekly tab that adds the three categories together and shows where the 40-hour line falls.
| A | B | C | D | E | F | G | H | I | |
|---|---|---|---|---|---|---|---|---|---|
| 1 | Date | Day | On-call start | On-call end | Standby hours | Calls received | Time actually worked (hrs) | Where the work happened | What the call was |
| 2 | Mon | 17:00 | 07:00 | 14 | 1 | 0.5 | Remote | Handled by phone from home | |
| 3 | Tue | 17:00 | 07:00 | 14 | 0 | 0 | No calls | ||

Setting the On-Call Rate Itself
No federal law sets an on-call pay rate for standby time, so once the compensability question is answered you are choosing a number. Three structures cover almost every small business: a flat amount for each on-call shift, a reduced hourly standby rate, or a stipend that covers a whole week or rotation.
Each one distributes the burden differently. A flat per-shift amount is the simplest to run, but it pays the same for a quiet Tuesday and a holiday weekend. An hourly standby rate tracks the length of the rotation honestly and costs more when rotations run long. A stipend is easiest on payroll and the least visible to the person carrying the phone.
Two constraints sit under whichever structure you pick. The first is a floor: if your determination says the standby time is compensable, the rate for those hours cannot fall below the applicable minimum wage. The second is the regular rate, the hourly rate that overtime is figured from.
Standby money is not neutral for overtime. Under the Department of Labor's regular-rate regulation, 29 CFR 778.223, on-call pay must be included in the regular rate even when the standby hours themselves are not hours worked. So the premium you choose also lifts the rate that each overtime hour is priced at.
Payments that state and local scheduling laws require for unused on-call shifts get the same treatment. Department of Labor Fact Sheet 56B puts them in the regular rate too, unlike some predictive-scheduling penalty payments that may be left out.
Price it against how often people are actually called, which is the number the log above produces. After a couple of months it will tell you whether the rotation deserves more money or fewer interruptions.
The Overtime Interaction Everyone Forgets
Here is the single most commonly missed piece of on-call pay, and it catches even employers who otherwise handle it correctly: compensable on-call time counts toward overtime.
The logic is simple but easy to overlook. If on-call hours count as hours worked, they are added to the employee's weekly total just like regular hours, and each must meet at least the federal minimum wage of $7.25 unless a higher state rate applies.
Take an employee who works 38 regular hours and then has 4 compensable on-call hours. That is 42 hours that week, and 2 of them are overtime, paid at 1.5 times the regular rate. Employers who correctly pay for the on-call time sometimes still forget that those same hours pushed the employee over 40.
When States Go Further Than Federal Law
Everything so far is the federal FLSA baseline. Several states go beyond it, and if you are in one of them, the federal rules are your floor, not your ceiling.
The main way states go further is reporting-time pay, sometimes called show-up pay: a rule that an employee who is required to report for a shift, or in some cases to call in for an on-call shift, must be paid a minimum amount even if they are ultimately sent home or not needed. There is no federal equivalent.
According to SHRM (2013), seven states and the District of Columbia impose reporting-time pay on adult employees: California, Connecticut, Massachusetts, New Hampshire, New Jersey, New York, and Rhode Island. Oregon has a rule as well, but it reaches minors only. SHRM found no reporting-time pay law in any other state.
Oregon's predictive-scheduling law, which requires advance notice of work schedules, adds an on-call rule for adults at large employers: retail, hospitality, and food-service employers with 500 or more employees worldwide owe half the regular rate for each scheduled on-call hour the employee is not asked to work.
| Layer | What it requires | Who sets it |
|---|---|---|
| Federal FLSA baseline | Pay for on-call time only when the employee is engaged to wait | Department of Labor (applies everywhere) |
| Reporting-time pay | A minimum payment when an employee reports or calls in but is sent home | Certain states, on top of the FLSA |
| Reporting-time jurisdictions | CA, CT, MA, NH, NJ, NY, and RI reach adult employees, plus DC. Oregon covers minors only | State law |
| Everywhere else | The FLSA analysis alone generally governs | Default federal rule |
The practical takeaway for a small business is that the federal analysis is necessary but not always sufficient. If you operate in a reporting-time-pay state, or fall under Oregon's predictive-scheduling rule, you have a second layer of rules on top of the FLSA, and they can require payment the federal test would not.
Layered obligations like this run through much of small-business employment law, which is why a one-size answer to whether you have to pay for on-call time does not exist.
Setting an On-Call Policy
The best protection against all of this complexity is a clear, written on-call policy decided in advance. It turns a fuzzy, dispute-prone situation into a set of known rules.
A written policy does double duty: it keeps you compliant by forcing you to think through the compensability and overtime questions in advance, and it keeps your team happy by making on-call duty predictable and fair rather than arbitrary.
Keeping those hours accurate and the whole arrangement documented is part of staying on the right side of payroll compliance, since the difference between a compliant on-call setup and an expensive one usually comes down to whether the records back up what you paid.
A practical way to start: complete the compensability worksheet for each rotation you run, keep the week log for a few weeks, and write your policy around what those two records show.
Frequently Asked Questions
What is on-call pay?
On-call pay is money paid to an employee for being available to work outside their regular hours, ready to respond when called. It has two sources. The first is the law: when on-call time counts as work under the Fair Labor Standards Act, the employer owes at least the minimum wage for it, and those hours count when overtime is figured. The second is the employer’s own policy. Plenty of businesses pay a flat rate, an hourly standby amount, or a stipend for carrying the phone, even where no statute requires it. Because both get the same name, owners often mix up what they must pay with what they choose to pay.
How does on-call pay work?
Everything hinges on whether the employee can use the on-call time effectively for personal purposes. When the restrictions are tight enough that they cannot, the employee is engaged to wait: those hours count as work, carry at least minimum wage, and count toward overtime. When the person is free to live their life and only has to stay reachable, they are waiting to be engaged, and under federal law the standby itself generally does not have to be paid, although any time spent actually handling a call is always paid. Separately, an employer may add a flat standby rate as a matter of policy. The question is decided case by case, on the specific facts of the arrangement.
What is the on-call pay rate?
There is no single legally mandated on-call rate for standby time under federal law. When on-call time counts as hours worked, it must be paid at least the applicable minimum wage, time actually spent working is normally paid at the employee’s regular rate, and hours over 40 in a week earn 1.5 times that rate. Beyond the minimum wage and overtime floors, employers set their own on-call or standby rates by policy: a flat amount per on-call shift, a reduced hourly standby rate, or a weekly stipend are all common. The right rate depends on your industry, how burdensome the on-call duty is, and what it takes to be fair to the employee and competitive as an employer.
Do you get paid for being on call?
Sometimes, and it depends on how restricted you are. Under the Fair Labor Standards Act, if your on-call restrictions are tight enough that you cannot use the time for your own purposes, for example you must stay on-site or respond within minutes and calls are frequent, that time is compensable work. If you are simply required to keep a phone on and stay reachable while otherwise free to go about your life, federal law generally does not require pay for the standby time itself, though you must be paid for any time you actually spend responding to a call. Some states go further than federal law, and many employers choose to pay a standby rate regardless.
How is on-call pay calculated?
Calculate it in layers. First, determine whether the on-call standby time is compensable under the engaged-to-wait test; if it is, it must be paid at least minimum wage. Second, pay any flat on-call or standby rate your policy provides for the standby period. Third, pay time actually spent working during a call at the regular rate. Fourth, check overtime: compensable on-call hours count toward the 40-hour weekly threshold, so hours over 40 are paid at 1.5 times the regular rate. One wrinkle catches people at that last step. The federal regular-rate regulation, 29 CFR 778.223, counts on-call pay in the regular rate whether or not the standby itself is hours worked, so standby money quietly raises what each overtime hour costs you.
Is on-call time considered hours worked?
It depends on the restrictions. Per the Department of Labor, on-call time is hours worked when the employee is required to remain on the employer’s premises, or is restricted so heavily that they cannot make effective personal use of the time. On-call time is generally not hours worked when the employee only has to tell the employer how to be reached and is otherwise free. The regulation frames this as engaged to wait, which is work time, versus waiting to be engaged, which is not. When the on-call time does count as hours worked, it must be paid and it counts toward the weekly overtime threshold.
How does on-call pay work for hourly employees?
For hourly, non-exempt employees, on-call pay follows the FLSA directly. Any on-call time that counts as hours worked is paid at least at minimum wage, time spent actually working during a call is normally paid at the regular hourly rate, and any hours over 40 in the week, including compensable on-call hours, are paid at 1.5 times the regular rate. Many employers also pay hourly workers a flat on-call rate or stipend for carrying the on-call duty, on top of these legal minimums. Hourly employees are exactly the group the FLSA on-call rules are designed to protect, so getting the classification and the hours-worked determination right matters most for them.
Does on-call pay count toward overtime?
Yes, when the on-call time is compensable. Compensable on-call hours are added to the employee’s other hours for the week, and anything above 40 is paid at 1.5 times the regular rate. Picture an employee with a 38-hour regular week who also logs 4 compensable on-call hours: that is 42 hours, so 2 of them are overtime. Employers sometimes get the pay right for compensable standby and still miss that the same hours can tip the week past 40, which makes this one of the most commonly overlooked points in on-call pay. Standby time that is not compensable stays out of the 40-hour count.
Do salaried exempt employees get on-call pay?
Generally not under the FLSA. Exempt employees are, by definition, exempt from the FLSA’s minimum wage and overtime rules, so the federal on-call compensability analysis does not apply to them in the same way. An exempt employee receives their salary regardless of hours, and the employer is not federally required to pay extra for on-call time. That said, many employers do provide an on-call stipend or premium to exempt staff as a matter of policy, because on-call duty is burdensome and paying for it aids retention and fairness. So for exempt employees, on-call pay is typically an employer choice rather than a legal obligation.
Do employers have to pay a minimum for on-call shifts?
Under federal law, nothing requires a minimum payment just for being scheduled on call when the time is not compensable and no call comes in. Some states differ. Reporting-time or show-up pay laws require an employer to pay a set minimum when a worker reports, or in some places only phones in, and is then sent home. A 2013 SHRM review counts seven states with this rule for adult employees, which are California, Connecticut, Massachusetts, New Hampshire, New Jersey, New York, and Rhode Island, along with the District of Columbia. Oregon’s version covers minors only. Separately, Oregon’s predictive-scheduling law adds an on-call payment of half the regular rate for each scheduled on-call hour that an employee is never asked to work, but only for retail, hospitality, and food-service businesses that have 500 or more employees worldwide. So whether you owe anything for an unused on-call shift depends on where the person works.
