On-Call Pay: Definition, When On-Call Time Is Work, and Stipends
On-call pay is compensation for time an employee must be available to work; under the FLSA, on-call time is paid work only when the employee is restricted enough that the time is spent mainly for the employer, while unrestricted on-call time is not, and any stipend for it is a matter of policy.
On-call pay is what an employee receives for the hours they must be available to work but are not actively working. Whether those hours must be paid at all depends on a single question the Fair Labor Standards Act (FLSA) has asked since the 1940s: is the employee "engaged to wait," which is work, or "waiting to be engaged," which is not? On-call time spent on the employer's premises is work. On-call time at home with a phone and freedom to live normally is generally not. Everything in between turns on how much the on-call rules restrict the employee, and everything the employer pays beyond the legal minimum is a policy choice worth writing down.
What Is On-Call Pay?
There are two layers to the term, and payroll disputes usually come from mixing them up.
The first layer is legal. If on-call time counts as hours worked, it must be paid at least the minimum wage and it counts toward the 40-hour overtime threshold like any other hour. DOL Fact Sheet #22 states the rule in two sentences: "An employee who is required to remain on call on the employer's premises is working while 'on call,'" while "an employee who is required to remain on call at home, or who is allowed to leave a message where he/she can be reached, is not working (in most cases) while on call." The fact sheet adds the qualifier that decides most cases: "Additional constraints on the employee's freedom could require this time to be compensated."
The second layer is policy. Many employers pay a stipend for unrestricted on-call time even though the law does not require it, because nobody wants to carry a pager for free. That stipend is compensation and, for non-exempt employees, it enters the regular rate of pay when overtime is calculated. And when the employee is actually called in, the hours spent working are always paid, at the overtime rate if the week's total goes past 40.
Engaged to Wait vs Waiting to Be Engaged
The fact sheet's examples are old but clear. A secretary who reads a book while waiting for dictation, or a firefighter who plays checkers while waiting for an alarm, is engaged to wait: the waiting is part of the job and is paid. An employee who is off duty, free to go where they like, and merely reachable is waiting to be engaged, and that time is not paid.
Courts have translated this into a set of factors for on-call arrangements away from the premises. None is decisive alone, but together they answer whether the time is spent predominantly for the employer's benefit:
- Response time. A requirement to be on site within 15 minutes confines the employee to a small radius; a two-hour window does not.
- Frequency of calls. An on-call shift that produces five call-outs a night is not free time between calls.
- Geographic limits. Being required to stay within the city, or at home, is a restriction.
- Ability to trade shifts. If the employee can swap on-call duty easily, the burden is lighter.
- Prohibition on alcohol or other activities. Restrictions on what the employee may do while waiting cut toward compensable time.
- Whether the employee can pursue personal activities. The ultimate test is whether the employee can use the time effectively for their own purposes.
An IT support engineer who must answer a page within 10 minutes and log in to a system every hour or two overnight is, in practice, working the whole shift. A nurse who must be reachable but is called once a month and can be anywhere within an hour's drive is not.
Three Kinds of On-Call Arrangements
| Arrangement | Is the waiting time paid? | What is paid |
|---|---|---|
| On premises (required to stay at the site) | Yes, all of it | Regular rate for every hour, overtime past 40 |
| Restricted off premises (short response time, frequent calls, location limits) | Usually yes, depending on the factors | Regular rate for the on-call period, plus time worked |
| Unrestricted off premises (reachable, free to live normally) | No, as a matter of law | Only time actually worked when called, plus any stipend the employer chooses |
The time actually spent working on a call is paid in every case, including the phone call itself, remote work from a laptop, and, for a call-out, travel to the site once the employee has been called (ordinary home-to-work commuting at the start of a regular shift is not paid, but a special call-out after hours generally is, and state rules vary).
A worked example
A managed-services company pays a remote network technician $30.00 an hour for a 40-hour week and puts her on unrestricted on-call duty for a seven-day week, paying a $150 stipend for it. During the week she takes three after-hours calls totaling 4.5 hours of work.
- Straight-time pay for the regular week: 40 × $30.00 = $1,200.00
- Call-out hours are overtime because the week's total is 44.5 hours: 4.5 overtime hours
- Regular rate including the stipend: ($1,200.00 + $150.00 + 4.5 × $30.00) ÷ 44.5 = $1,485.00 ÷ 44.5 = $33.37
- Overtime premium owed: 4.5 × $33.37 × 0.5 = $75.08
- Straight time for the call-out hours: 4.5 × $30.00 = $135.00
- Total: $1,200.00 + $150.00 + $135.00 + $75.08 = $1,560.08
Two things the example shows. The stipend raised the overtime rate from $45.00 to $50.06 per hour, because a flat on-call payment is included in the regular rate. And if the response window had been 10 minutes with calls every hour, the whole on-call period would have been hours worked and the arithmetic would have been very different.
State rules can be stricter
Several states have reporting-time or call-in pay rules that require a minimum payment when an employee is called in and sent home early, and some treat restricted on-call time more generously than the federal test. Confirm the rules with your state labor agency or the U.S. Department of Labor before setting an on-call policy.
Common Stipend Structures
Employers that pay for unrestricted on-call time use a few patterns. None is required by federal law, and the amounts here are illustrative rather than benchmarks: a flat daily or weekly stipend ($25 to $50 a day is a range often seen in IT and healthcare job postings, though it varies widely by industry and region); a small hourly rate for every on-call hour, such as one or two dollars, which is easy to administer but adds up over a 128-hour off-duty week; a guaranteed minimum for each call-out, such as two hours of pay even if the fix takes 20 minutes; and a higher rate for the hours actually worked during a call-out. Whatever the structure, it should be written into the on-call policy with the response-time expectation, because the response time is what determines whether the waiting hours become compensable.
On-Call Pay in Contact Centers and Remote Teams
A 24-hour technical support desk staffs the overnight with two agents and puts a third on unrestricted on-call from home for overflow. The on-call agent is paid a $40 shift stipend and her normal rate for any hours she logs in. If the desk starts paging her nightly and expects her at her workstation within 10 minutes, the arrangement has crossed into restricted on-call and the waiting hours should be paid, which usually makes it cheaper to simply schedule a third agent. Remote teams face the same trap with informal expectations: an engineer who is "not on call" but is expected to answer chat messages within minutes all evening is, in the law's terms, engaged to wait.
How to Track On-Call Time
Two records settle on-call disputes: when the employee was on call, and when they actually worked. HiveDesk scheduling lets a manager put on-call shifts on the roster so the on-call period and its owner are documented in advance, and the desktop, mobile, and browser apps timestamp every work session, so a 20-minute call-out at 2 a.m. is recorded as 20 minutes of work at 2 a.m. rather than reconstructed the next morning. Timesheets total call-out hours inside the workweek so payroll can see whether they crossed the 40-hour line and apply the overtime rate with the stipend included. All of this is included in the single $5/user/month plan with a 14-day free trial.
Timestamp Every Call-Out, Not Just the Shift
HiveDesk schedules on-call periods and records the exact minutes worked during them, so stipends, call-out pay, and overtime rest on real records. $5/user/month, 14-day free trial.

Frequently Asked Questions
Do employers have to pay for on-call time? Only when the on-call time counts as hours worked: when the employee must stay on the premises, or when the restrictions off premises are tight enough that the time is spent mainly for the employer. Unrestricted on-call time where the employee simply must be reachable is not paid under federal law, though the time actually spent working on a call always is.
Is on-call pay required by law? A stipend for unrestricted on-call time is not required by the FLSA. Pay for restricted or on-premises on-call time, and for all hours actually worked, is required.
What is a typical on-call rate? There is no legal rate. Employers commonly use a flat daily or weekly stipend, a small hourly amount for on-call hours, or a guaranteed minimum per call-out. Amounts vary widely by industry, so treat any figure as illustrative.
Does on-call time count toward overtime? If it is compensable on-call time, yes, every hour counts toward the 40-hour threshold. If it is unrestricted and unpaid, only the hours actually worked count, but a flat stipend is included in the regular rate used to compute overtime.
Can a salaried exempt employee be required to be on call without extra pay? Yes. Exempt employees are not covered by the FLSA's hours-worked or overtime rules, so an employer may require on-call availability without additional pay, subject to any contract or state rule.
What is the difference between on-call pay and call-in pay? On-call pay covers availability. Call-in or reporting-time pay is a minimum payment some states require when an employee reports to work and is sent home early, whether or not they were on call.
