In most U.S. jobs, your employer can require you to be on call, and refusing an assigned on-call shift can be grounds for discipline or termination. The harder question is whether that time has to be paid, and the answer turns on how much the employer restricts what you can do while you wait. If you’re mostly free to live your life and just need to answer the phone, the hours usually aren’t paid. If the restrictions are tight enough that the time isn’t really yours, they usually are.
Why Your Employer Can Require It
At-will employment covers the vast majority of U.S. jobs. It lets your employer set and change the terms of your position, including adding on-call responsibilities. If on-call availability was part of the job when you were hired, accepting the role meant accepting the duty. If it gets added later, your practical options are to comply or leave. No federal law prohibits employers from requiring on-call shifts, and few states restrict the practice itself.
The exceptions are narrow. A union contract may limit how often you can be placed on call. An individual employment agreement may carve out specific protections. Safety-sensitive industries like trucking and aviation have separate rules governing rest periods between shifts. Outside those situations, the scheduling power sits with the employer.
When On-Call Time Has to Be Paid
Federal regulations draw the line based on how restricted you are. Under 29 CFR 785.17, an employee who must remain on the employer’s premises, or stay so close that the time can’t be used for personal purposes, is working while on call. An employee who simply has to leave a number where they can be reached is not.
That handles the easy cases. A nurse sleeping in a hospital break room is working. A plumber who carries a phone at home and gets called once a week is not. The hard cases fall in between, and courts look at the real-world restrictions on your life to decide which side of the line you’re on.
What Courts Look At
When you’re allowed to wait off-site, the question is how much freedom you actually have. Several factors matter:
- Response time. A 20-minute callback window confines you to a small area and sharply limits what you can do. A six-hour window barely restricts you. In one case, a 20-minute callback requirement was restrictive enough to make firefighters’ on-call time compensable.
- Call frequency. Being called in five times during an eight-hour on-call window is very different from being called once a month. Frequent interruptions make it harder to use the time for anything else.
- Geographic limits. Some employers require you to stay within a certain radius of the worksite. The tighter the radius, the more the time looks like work.
- Whether you can actually live your life. Can you go to a movie, have dinner with your family, run errands? Or are you sitting by the phone? Courts examine the actual arrangement rather than applying a rigid formula.
No single factor decides it. The more your personal life is curtailed, the stronger your case that the time is compensable.
Meals and Long Shifts
A meal break only counts as unpaid time if you are completely relieved from duty. If you have to monitor a radio or stay available for calls while eating, the meal period is paid work time. For on-call assignments of 24 hours or more, common in healthcare, fire protection, and residential care, employers and employees can agree to exclude up to 8 hours of sleep from paid hours, but only if the employer provides adequate sleeping facilities and you usually get an uninterrupted night’s sleep. Any call to duty during that sleep period is paid time.
Pay Rules Once the Time Counts
When on-call time qualifies as compensable work, the Fair Labor Standards Act governs how it must be paid. The rules apply to non-exempt (typically hourly) employees.
Minimum Wage and Overtime
All compensable on-call hours count toward your total hours worked. Your employer must pay at least the federal minimum wage of $7.25 per hour for those hours. Many states set higher minimums, and the higher rate applies.
These hours also count for overtime. Non-exempt employees earn one and a half times their regular rate for every hour beyond 40 in a workweek. If your regular duties total 38 hours and you log 6 compensable on-call hours, you’ve worked 44 hours, and the last 4 are overtime.
Stipends Get Folded In
Many employers pay a flat stipend for on-call shifts regardless of whether calls come in. Under the FLSA, the regular rate of pay includes all remuneration for employment, and the Department of Labor treats on-call stipends as compensation that must be folded into the regular rate when calculating overtime. The stipend doesn’t just sit on top of your pay; it raises the hourly rate used to compute your overtime premium.
If You’re Exempt
Workers classified as exempt under the FLSA’s executive, administrative, or professional exemptions aren’t entitled to overtime or separate on-call compensation. Their salary is meant to cover all hours worked. To qualify as exempt, an employee must meet both a duties test and a salary test. The enforceable minimum salary is $684 per week ($35,568 annually) under the 2019 rule. If your salary falls below that floor or your duties don’t fit the exemption, you’re non-exempt regardless of your job title, and the on-call pay rules apply.
Travel Time and Equipment Costs
Normal commuting from home to your regular worksite is generally not paid, even when you’re called in unexpectedly. Once you arrive and start working, everything from that point until you’re released is compensable. If you’re called out after finishing your regular workday and must travel a substantial distance to handle an emergency at a different location, all travel time is working time. The DOL has declined to take a position on travel back to your regular workplace for an emergency callback, so those disputes often hinge on state law or company policy.
If your employer requires you to carry a pager, phone, or other device while on call, the FLSA treats it like a required uniform: the employer cannot make you pay for it if doing so would push your effective hourly earnings below minimum wage for any workweek. That applies to both direct paycheck deductions and reimbursement arrangements where you buy the equipment and the employer subtracts the cost later.
State Laws and Private Agreements Can Add Rights
Even when on-call time isn’t compensable under federal law, your state may still require some payment. A number of states have reporting-time or show-up pay laws that guarantee a minimum number of paid hours, often 2 to 4, whenever you’re required to report to work or make yourself available for a shift. Some jurisdictions have extended these laws to on-call employees who must check in to find out whether they’re needed. The rules vary. Check with your state’s labor department. State law can only add to the federal floor; it can never cut below it.
Private agreements can also go further than the law requires. A union contract might guarantee a flat-rate stipend for every on-call shift, a minimum number of paid hours per callback, or a cap on how many on-call weekends you can be assigned per month. An individual employment contract can do the same. Even without a formal contract, an employee handbook that promises a stipend or a minimum response time can create binding obligations. Read your contract, collective bargaining agreement, and handbook carefully.
What to Do If You Think You’re Owed Pay
Start keeping your own records now. Federal law requires employers to track hours worked, but many don’t accurately record on-call time. Keep a log noting when each on-call shift started, when it ended, every time you were called or restricted, and what you had to do. Save texts, emails, and call logs.
You can file a complaint with the Department of Labor’s Wage and Hour Division at 1-866-487-9243. Complaints are confidential, and federal law prohibits your employer from retaliating against you for filing one. Retaliation includes firing, demoting, cutting hours, or any other form of discrimination based on your complaint.
The federal statute of limitations for recovering unpaid wages under the FLSA is two years from the date of the violation, or three years if the violation was willful. State deadlines may differ. The clock is already running on pay you’ve missed, so don’t wait to look into it.
