Whether you get paid for being on standby comes down to one question: how much does your employer’s on-call arrangement actually restrict what you can do? If the restrictions are tight enough that the time really belongs to your employer, it counts as hours worked and must be paid. If you’re free to live your life and simply need to be reachable, federal law generally doesn’t require payment. Most disputes live in the middle.
Engaged to Wait vs. Waiting to Be Engaged
The Fair Labor Standards Act splits standby into two categories. An employee “engaged to wait” is working and must be paid. An employee “waiting to be engaged” is not working and doesn’t need to be paid. The difference turns on who benefits from the waiting.
A worker required to stay on the employer’s premises while on call is working, even if allowed to sleep, read, or watch TV between tasks. The Department of Labor’s guidance uses the example of a firefighter playing checkers while waiting for an alarm — that’s paid time because the employer is dictating where the employee must be.1U.S. Department of Labor. Fact Sheet #22: Hours Worked Under the Fair Labor Standards Act (FLSA)
At the other end, an employee who simply carries a phone and can be reached if needed, but is otherwise free to run errands, see friends, or stay home, is generally not considered to be working while on call.1U.S. Department of Labor. Fact Sheet #22: Hours Worked Under the Fair Labor Standards Act (FLSA) The catch is that additional constraints on your freedom can pull the time back into the paid category.
What Pushes Standby Into Paid Time
No single factor decides it. Courts look at the arrangement as a whole to see whether it genuinely lets you use the time or effectively ties you to the job.
- Response time. A 15- or 20-minute window shrinks where you can go. If you can’t reasonably get to a restaurant, a gym, or a friend’s house and still respond in time, that points toward paid time.
- Geographic limits. A tight radius around the worksite has the same effect as a short response window.
- Call frequency. Even a generous response time loses meaning if calls come every 30 minutes. Constant interruptions make personal activity impossible.
- Shift trading. If you can hand off on-call duty to a willing coworker, that flexibility cuts against paid time.
- Consequences for missing a call. Discipline or termination for a missed call signals that the employer treats the time as a job obligation.
Weigh these together. A 30-minute window with rare calls and free shift-swapping looks like personal time with a phone nearby. A 15-minute window with calls coming all night looks like working from home under a different label.
How Compensable Standby Gets Paid
When standby time qualifies as hours worked, it must be paid at no less than the federal minimum wage of $7.25 per hour, or your state’s minimum wage if it’s higher. Those hours add to your regular hours for the week. If the total exceeds 40, you’re owed overtime at one and a half times your regular rate for every hour past 40. Someone who works 35 regular hours and logs 10 hours of compensable standby has worked 45 hours and is owed five hours of overtime.1U.S. Department of Labor. Fact Sheet #22: Hours Worked Under the Fair Labor Standards Act (FLSA)
Employers can set a lower hourly rate for standby than for active work, as long as the standby rate meets minimum wage. A hospital might pay a nurse $35 an hour for active shifts and $12 an hour for on-call time. When overtime kicks in, the regular rate used for the overtime calculation has to reflect both rates. The FLSA uses a weighted average: total earnings from all rates divided by total hours worked.2eCFR. 29 CFR 778.115 – Employees Working at Two or More Rates If your pay stub shows overtime calculated only against your active rate, or only against your standby rate, that’s a common error to check.
The Sleep-Time Rule for 24-Hour Shifts
If you’re on duty for 24 hours or more — common in healthcare, fire departments, and residential care — your employer can exclude up to eight hours of sleep time from paid hours, but only if all of these conditions are met:
- You and the employer have an agreement, written or implied, to exclude the sleep period.
- The employer provides adequate sleeping facilities.
- You can usually get at least five consecutive hours of sleep, meaning interruptions happen less than half the time over a sustained period.
Even when every condition is met, only eight hours can be excluded, no matter how long you actually sleep. Every interruption during the sleep period counts as hours worked.3U.S. Department of Labor. FLSA Hours Worked Advisor – Sleep Time If there’s no agreement about excluding sleep, the employer can’t deduct any of it. Some employers quietly deduct sleep hours without ever establishing the required agreement.
Salaried Exempt Employees
The pay rules above apply to non-exempt employees — workers eligible for overtime. Salaried employees properly classified as exempt under the FLSA are in a different position. The engaged-to-wait test doesn’t generate extra pay for them because the FLSA’s overtime and minimum wage rules don’t apply the same way.
An exempt employee receives a predetermined salary that can’t be reduced based on hours worked in a given week.4U.S. Department of Labor. Fact Sheet #17G: Salary Basis Requirement and the Part 541 Exemptions Under the Fair Labor Standards Act (FLSA) Perform any work in the week, including answering an on-call request, and you’re owed your full salary. But no extra pay is required for on-call hours, however restrictive the arrangement.
The salary threshold for the most common FLSA exemptions is $684 per week.5U.S. Department of Labor. Earnings Thresholds for the Executive, Administrative, and Professional Exemptions If your salary is below that, you may be misclassified, and the non-exempt on-call rules would apply to you.
State Rules and Reporting Time Pay
The FLSA is a floor. States can require payment for on-call time in circumstances federal law doesn’t cover, define compensable standby more broadly, or apply tighter response-time thresholds. When federal and state rules point in different directions, the rule more favorable to the employee applies. An arrangement that passes the federal test can still violate your state’s wage and hour laws.
Separately, roughly a dozen states and territories require reporting time pay: a minimum amount you get when you actually show up (or are called in) and the work isn’t there or ends early. The minimums range from one hour to four hours, with some jurisdictions tying the guarantee to half the scheduled shift. These laws apply even if the on-call waiting itself wasn’t paid — the trigger is reporting to work. If you’re regularly called in for short bursts, check whether your state has one of these rules; short callbacks add up.
Travel Time When You’re Called In
Time spent actually working after a call is always paid. Travel time is the trickier piece. The general FLSA rule treats an ordinary commute as unpaid. Emergency call-backs are treated differently because the trip results from something that couldn’t be scheduled in advance. When an on-call employee is summoned to the worksite outside normal hours for an urgent need, the travel time to get there is generally compensable. If the employer gives you discretion about when to leave, the urgency argument weakens, and the travel may not qualify.
If You Should Have Been Paid and Weren’t
You can file a complaint with the Department of Labor’s Wage and Hour Division online or by calling 1-866-487-9243. The agency routes the complaint to the nearest field office, contacts you within two business days, and investigates if warranted.6Worker.gov. Filing a Complaint With the U.S. Department of Labor’s Wage and Hour Division (WHD)
Before you file, pull your records together: on-call schedules, the specific restrictions the employer imposed (response window, geographic limits, call frequency), and pay stubs showing the time went uncompensated. Specific documentation strengthens the claim.
An employer who fails to pay required wages owes the unpaid amount plus an equal amount in liquidated damages, effectively doubling the recovery.7Office of the Law Revision Counsel. 29 U.S. Code 216 – Penalties The employer can escape liquidated damages only by proving to a court that it acted in good faith and had reasonable grounds to believe its practices were lawful.8Office of the Law Revision Counsel. 29 U.S. Code 260 – Liquidated Damages Prevailing employees are also awarded attorney’s fees.
The filing deadline is two years for unpaid wages, extended to three years if the violation was willful, meaning the employer knew or showed reckless disregard for whether its practices violated the law.9Office of the Law Revision Counsel. 29 U.S. Code 255 – Statute of Limitations The clock runs from each pay period where you should have been paid but weren’t, not from the date you first started on-call duty. Every pay period that ages past the limitation window is money you can no longer recover.
