On-Call Pay Laws: When Waiting Time Has to Be Paid, and When It Does Not
There is no federal law requiring on-call pay as such. What federal law does instead is decide whether the on-call hours are hours worked — and if they are, every one of them must be paid at least the minimum wage and must count toward overtime. The line is drawn in 29 CFR 785.17: an employee required to remain on call on the employer's premises “or so close thereto that he cannot use the time effectively for his own purposes is working while ‘on call’,” while an employee “merely required to leave word at his home or with company officials where he may be reached is not working while on call.” Everything else — stipends, per-shift payments, callout minimums — is policy, not law.
The rule, and where it comes from
The Fair Labor Standards Act does not say “pay employees for being on call.” It says employers must pay at least the minimum wage for all hours worked, and overtime beyond forty in a week. So the entire question collapses into one: are the on-call hours hours worked?
The Department of Labor's answer starts at 29 CFR 785.14, which sets the general approach for waiting time. Whether it counts “depends upon particular circumstances,” and the determination involves “scrutiny and construction of the agreements between particular parties, appraisal of their practical construction of the working agreement by conduct, consideration of the nature of the service, and its relation to the waiting time, and all of the circumstances.” The regulation then quotes the sentence that has governed this area since 1944: “Facts may show that the employee was engaged to wait or they may show that he waited to be engaged.”
If that sounds unhelpfully abstract, the regulation adds a usable instruction: such questions “must be determined in accordance with common sense and the general concept of work or employment.”
The two ends of the line
29 CFR 785.15 (“On duty”) describes waiting that is work — the messenger doing a crossword between assignments, the firefighter playing checkers between alarms, the repair man waiting for a customer to get the premises ready. The regulation's reasoning is what matters: the periods “are unpredictable…usually of short duration…the employee is unable to use the time effectively for his own purposes. It belongs to and is controlled by the employer.”
29 CFR 785.16 (“Off duty”) describes the other end: periods where the employee is “completely relieved from duty and which are long enough to enable him to use the time effectively for his own purposes are not hours worked.” And it adds a condition employers routinely miss — the employee “is not completely relieved from duty…unless he is definitely told in advance that he may leave the job and that he will not have to commence work until a definitely specified hour has arrived.”
On-call pay under the FLSA: engaged to wait, or waiting to be engaged
FLSA on-call pay is not a separate entitlement. The Fair Labor Standards Act pays for hours worked, and the Department of Labor sorts on-call time into hours worked or not by one distinction, which its Fact Sheet #22 puts plainly: the facts may show that the employee was engaged to wait, which is work time, or that the employee was waiting to be engaged, which is not. Three sections of 29 CFR part 785 draw that line, and two more deal with the case frontline employers ask about most, sleeping on shift.
| Situation | Treatment under the FLSA | Source |
|---|---|---|
| Required to remain on call on the employer's premises, or so close to them that the time cannot be used effectively for the employee's own purposes | Hours worked (engaged to wait) | 29 CFR 785.17 |
| Waiting on the job for periods that are unpredictable and usually short, which the employee cannot use effectively for their own purposes | Hours worked (engaged to wait) | 29 CFR 785.15 |
| Merely required to leave word at home or with company officials where they can be reached | Not hours worked (waiting to be engaged) | 29 CFR 785.17 |
| Completely relieved from duty, told in advance they may leave and when they must be back, for a period long enough to use effectively | Not hours worked | 29 CFR 785.16 |
| On duty for less than 24 hours, even if allowed to sleep or do personal things when not busy | Hours worked, including the sleep | 29 CFR 785.21 |
| On duty for 24 hours or more | Employer and employee may agree to exclude a bona fide, regularly scheduled sleeping period of up to 8 hours, if adequate sleeping facilities are furnished and the employee can usually get an uninterrupted night's sleep. Calls during it count; if the employee cannot get at least 5 hours' sleep, the whole period counts. | 29 CFR 785.22 |
Most real rotas sit somewhere between those rows, which is why the factors further down this page matter. Two consequences hold either way. Time actually spent on a callout is hours worked whichever row the waiting falls into. And where the waiting itself is engaged-to-wait time, it counts toward the forty-hour overtime threshold, so a rota that looks like a stipend question is usually an overtime question.
Is your rota compensable?

On-call compensability check
The factors that actually decide it
Courts applying 785.17 have converged on a small set of practical questions, all of which are versions of the same one: how much of the employee's own time is left?
Geographic restriction
The single heaviest factor. Requiring presence on the premises settles it. Requiring the employee to stay within a radius or a travel time is the contested middle, and the tighter the radius the closer it comes to the on-premises case.
Required response time
A geographic restriction by another name. A fifteen-minute callout window in a spread-out service area is functionally a requirement to sit near the depot, whatever the policy says about being free to go home.
Frequency of calls
A rota where most shifts pass quietly leaves the time usable. A rota where the phone goes four times a night does not, and the fact that each call is short does not help — 785.15 makes the point that unpredictable, short interruptions are precisely what makes time unusable.
Ability to trade the shift
Being able to swap with a colleague reduces the restriction, because the employee retains some control over their own time. A fixed rota with no trading increases it.
What the employee can actually do
The practical test behind all of the above. If an on-call employee can sleep normally, mind children, leave the house, and have a drink, the time is theirs. If they cannot, it is not, whatever the handbook calls it.
The mistake that costs the most
The expensive error is not paying too little for on-call time. It is paying a flat stipend, assuming that settles it, and then discovering the hours were compensable all along. If the waiting time counts as hours worked, a $50 shift stipend does not discharge the obligation — those hours must be paid at least the minimum wage and, crucially, must be counted toward the forty-hour overtime threshold. An employee who works 38 scheduled hours and is on call for 60 compensable hours has worked 98 hours that week. That is where the liability lives, and it accrues quietly across every employee on the rota for as long as the arrangement runs.
What the stipend is, and is not
Most employers pay something for on-call duty — a per-shift amount, a flat weekly figure, sometimes a minimum number of paid hours per callout. None of that is federally required. It exists because on-call rotas are unpopular and because paying for them is easier than losing people over them.
Two cautions apply even where the waiting time is not compensable. First, time actually spent responding to a call is work and must be paid, including, in most cases, travel time between calls once the employee has begun working. Second, an on-call payment that is not a discretionary bonus generally has to be included in the regular rate when overtime is calculated — which means paying a stipend can raise the cost of every overtime hour that week. Neither point is exotic, and both are routinely missed.
Where state law changes the answer
The federal position above is a floor. Several states are stricter about when on-call time is compensable, and a separate group of states and cities have reporting-time or predictive-scheduling rules that create obligations the FLSA does not.
Reporting-time pay generally requires an employer to pay something when an employee reports for a scheduled shift and is sent home early or not put to work — and in some jurisdictions the rules extend to on-call shifts that are canceled. Predictive scheduling laws, which apply to specified industries in a growing number of cities and at least one state, typically require advance notice of schedules and premium pay for late changes, which can include calling someone in at short notice.
Because these rules are local, differ substantially, and change, the practical instruction is unglamorous: check your own jurisdictions before writing the policy, and check them again when you open a location in a new one. This page cannot do it for you and should not pretend to.
If the rota is the reason people leave, the durable fix is more people on it. Our guides to employer branding on a budget and to white-label recruitment marketing cover two routes to that.
Reporting time (show-up) pay by state
Reporting time pay, also called show-up pay, is a minimum payment owed when someone reports for a shift and is sent home early or given no work. Federal law does not require it. It only says how to treat it if you pay it: under 29 CFR 778.220 the part of a show-up payment that exceeds pay for the hours actually worked is “not made for hours worked”, so it may be left out of the regular rate and cannot be credited toward overtime owed. The obligation itself comes from the states. These four were read at source on 24 September 2026:
| State | What is owed | Main exceptions | Source |
|---|---|---|---|
| California | Half the usual or scheduled day’s work, at least 2 and at most 4 hours at the regular rate, when the employee is not put to work or gets less than half the scheduled day. A second report in the same day with under 2 hours of work earns 2 hours. | Threats to people or property, failure of public utilities, acts of God or other causes outside the employer’s control; paid standby; shifts regularly scheduled under 2 hours | DLSE; IWC orders, section 5 |
| New Hampshire | At least 2 hours’ pay at the regular rate on any day the employee reports at the employer’s request | County and municipal employees; certain ski instructors; employers who made a good-faith effort to stop the employee reporting | RSA 275:43-a |
| New Jersey | At least 1 hour at the applicable wage rate when the employee reports for duty at the employer’s request | Not owed if the employer made available the minimum hours agreed before work began that day | N.J.A.C. 12:56-5.5 |
| Rhode Island | At least 3 times the regular hourly rate when an employee reports at the start of a shift and is given less than 3 hours of work | Shorter shifts by voluntary agreement; full-time students employed by their college or university are paid for the agreed shift instead | R.I. Gen. Laws 28-12-3.2 |
Other states have call-in or reporting-pay rules in their wage regulations that could not be read at source for this page, and the city and state fair workweek laws add premiums for shifts cut or canceled at short notice; those are on fair workweek laws and predictive scheduling laws by state. This table is not a complete list, so check your state labor agency before relying on the absence of a rule.
What this page cannot do
It cannot tell you whether your specific arrangement is compensable, because 785.14 makes clear the answer depends on all the circumstances, including how the arrangement works in practice rather than how it is written. Two employers with identical policies can land on opposite sides of the line if one calls people constantly and the other almost never does.
It also cannot cover your state. The federal rules quoted here are the minimum; several states impose stricter tests, and reporting-time and predictive-scheduling rules sit on top of them.
What it can do is tell you which questions decide the outcome, so that you can either write the rota to sit clearly on one side of the line, or price the arrangement honestly rather than discovering the cost in a back-pay claim.
Frequently asked questions
Is there a federal law requiring on-call pay?
No. The Fair Labor Standards Act does not require a separate on-call premium. What it requires is that all hours worked be paid at least the minimum wage and counted toward overtime, so the question is whether the on-call hours themselves count as hours worked. If they do, they must be paid; if they do not, only time actually spent responding to calls must be paid, and any on-call stipend is a matter of employer policy.
When does on-call time have to be paid?
Under 29 CFR 785.17, an employee who is required to remain on call on the employer's premises, or so close to them that they cannot use the time effectively for their own purposes, is working while on call. An employee who is not required to remain on the premises but is merely required to leave word at home or with company officials where they may be reached is not working while on call. The practical test is how much of the employee's own time is left after the restrictions.
What factors decide whether on-call time counts as hours worked?
The main ones are any geographic restriction, the required response time, how often the employee is actually called, whether they can trade or decline the shift, and whether they can carry on ordinary personal activities such as sleeping, minding children or leaving the area. 29 CFR 785.14 frames the inquiry as an appraisal of all the circumstances, to be determined in accordance with common sense and the general concept of work or employment, and asks whether the employee was engaged to wait or waited to be engaged.
Does paying an on-call stipend satisfy the law?
Not by itself. If the waiting time counts as hours worked, those hours must be paid at least the minimum wage and must count toward the forty-hour overtime threshold, and a flat per-shift stipend will usually fall short of that. Separately, an on-call payment that is not a discretionary bonus generally has to be included in the regular rate when overtime is calculated, which raises the cost of overtime hours in weeks when it is paid.
Does an employee have to be told in advance that they are off duty?
Yes, for the time to count as off duty under 29 CFR 785.16. The regulation states that an employee is not completely relieved from duty and cannot use the time effectively for their own purposes unless they are definitely told in advance that they may leave the job and that they will not have to commence work until a definitely specified hour has arrived. Vague or open-ended release from duty does not meet that standard.
Is time spent responding to an on-call phone call paid?
Yes. Time actually spent working is hours worked regardless of whether the surrounding waiting time is compensable, and that generally includes travel between jobs once the employee has begun working. Employers who treat the waiting time as unpaid still need a reliable way for employees to record the time they spend responding, because the obligation to pay it does not depend on the employee remembering to ask.
Do state laws add on-call requirements?
Often. Some states apply a stricter test than the federal one for when on-call time is compensable. Separately, reporting-time pay rules in several jurisdictions require payment when an employee reports for a shift and is sent home or not put to work, and in some places extend to canceled on-call shifts, while predictive-scheduling laws in a growing number of cities require advance notice of schedules and premium pay for late changes. Check the rules in every jurisdiction where you have staff before writing an on-call policy.
Does Fair Labor Standards Act on-call pay cover time spent sleeping?
It depends on the length of the duty period. Under 29 CFR 785.21, an employee required to be on duty for less than 24 hours is working even though they are permitted to sleep when not busy, so the sleep is paid. For duty of 24 hours or more, 29 CFR 785.22 lets the employer and employee agree to exclude a bona fide, regularly scheduled sleeping period of not more than 8 hours, provided adequate sleeping facilities are furnished and the employee can usually enjoy an uninterrupted night's sleep. Without such an agreement the sleeping time counts. Any call to duty during the sleep period is hours worked, and if the employee cannot get at least 5 hours' sleep, the entire period counts.
What is reporting time pay?
It is a minimum payment owed when an employee reports for a scheduled shift and is sent home early or given no work. There is no federal requirement, but some states have one. In California it is half the scheduled day, at least 2 and at most 4 hours at the regular rate (DLSE). New Hampshire requires 2 hours, New Jersey 1 hour, and Rhode Island 3 times the regular hourly rate when less than 3 hours of work is given.
