FLSA On-Call Pay: When Waiting Time Must Be Paid
DOL Fact Sheet #22 and 29 CFR 785.17: on-call on premises is work; home on-call usually is not unless restrictions block personal use. Table of factors, call-back pay, and state overlays.
At a glance
Under the FLSA, on-call time on the employer's premises is hours worked. On-call at home, or leaving a message where you can be reached, is usually not hours worked, unless extra limits make the time unusable for personal purposes. Wage and Hour Fact Sheet #22 draws that line; 29 CFR §785.17 uses the same "engaged to wait" vs "waiting to be engaged" idea. Minutes spent actually responding to a call always count as work time. This page is a decision table for payroll and managers, not legal advice for a specific dispute. Meal-period rules overlap when someone stays "on duty" at lunch; see federal lunch break laws. Paycheck timing fights are separate: can an employer withhold a paycheck.
- Map whether the employee must remain on premises or so close that personal time is blocked
- List response windows, geographic limits, uniform rules, and how often calls actually come
- Decide: compensable waiting vs unpaid waiting-to-be-engaged under Fact Sheet #22
- Pay all time spent answering, traveling for a call-back, or performing work after a page
- Check state wage orders that may be stricter than the federal baseline
- Document the policy employees actually follow, not the brochure version
- Fail the review if unpaid "on call" requires sitting at the worksite with no free use of time
§1Quick answer
"FLSA on-call pay" is less about a special premium rate and more about whether the waiting block counts as hours worked. DOL's Fact Sheet #22 states: an employee required to remain on call on the employer's premises is working while on call; an employee on call at home, or allowed to leave a message where they can be reached, is not working in most cases, but additional constraints can tip the time into compensable hours [DOL Fact Sheet #22, revised July 2008, checked 2026-10-19].
The regulation behind that summary is 29 CFR §785.17: remaining on the premises, or so close that the employee cannot use the time effectively for their own purposes, means the on-call period is work; merely leaving word where you may be reached generally does not [29 CFR §785.17]. Courts and WHD opinion letters then weigh how restrictive the real schedule is.
§2Decision table: paid waiting vs unpaid waiting
Fill the middle column from your written policy and from what supervisors actually enforce. If the two disagree, payroll should price the stricter practice.
| Factor | More likely unpaid waiting | More likely paid hours worked | Primary source |
|---|---|---|---|
| Location | Home / free to leave worksite | Must stay on premises | Fact Sheet #22; §785.17 |
| Contact rule | Leave a number / carry a pager only | Must remain so close personal use is blocked | §785.17 |
| Response window | Reasonable report time; rare calls | Very short response (e.g. minutes) plus frequent pages | WHD opinion letters (fact-specific) |
| Geographic / attire limits | Broad area; normal clothes | Tight radius, must wear kit, cannot trade shifts | FLSA2008-8NA style analysis |
| Time on a call | N/A: always pay the response | All duties after the page until released | Fact Sheet #22 hours-worked principles |
| Meal overlap | Truly relieved meal away from duty | Must answer phones / monitor while "eating" | Fact Sheet #22 meal section |
WHD's May 23, 2008 non-administrator letter on an ambulance service (FLSA2008-8NA) shows how fact patterns swing: an eight-minute response rule, tight coverage area, identifying attire, and little ability to swap shifts pushed winter on-call time toward compensable hours when calls were frequent, while quieter seasons with the same formal rules could still be treated as non-compensable waiting depending on actual restrictiveness [DOL FLSA2008-8NA PDF]. Treat that letter as an illustration of the test, not a safe harbor for your industry.
§3What always gets paid
Even when the idle on-call block is unpaid, the clock starts when the employee is called in. Travel that is part of responding, phone troubleshooting, and on-site work until release all feed the workweek for minimum wage and overtime. Fact Sheet #22's broader "suffer or permit to work" rule still applies if supervisors know people are answering tickets off the clock, those minutes count.
Exempt employees are a different analysis. The on-call hours-worked rules above target nonexempt pay. Mislabeling someone as exempt to dodge overtime is outside this page; keep duties tests and salary basis rules with counsel.
Call-back travel that is part of responding rolls into the same workweek as the on-site minutes. If a nonexempt employee already worked 38 hours and then drives in for a two-hour overnight call-back, those hours stack toward the overtime threshold for that workweek under ordinary FLSA weekly aggregation. A flat on-call stipend does not wipe those hours-worked minutes; Fact Sheet #22 still expects you to count time the employer suffers or permits. Track stipend and hours in parallel so overtime math stays auditable.
§4State overlays and policy drafting
Several states publish wage orders or case law that treat restrictive on-call more aggressively than the federal baseline. When both apply, payroll should follow the rule that yields more employee protection for that jurisdiction. Put the federal test and any state add-ons in the same handbook section so managers stop inventing "pager means free."
Write the response expectation in minutes, the geographic radius in miles, whether trading shifts is allowed, and how call frequency is reviewed. Then sample a month of pages. A policy that claims "rarely called" while logs show nightly interruptions is the pattern WHD letters scrutinize.
Recordkeeping still matters: if you pay a flat on-call stipend, confirm it does not undercut overtime calculations when response time pushes a nonexempt employee over 40 hours. Stipends do not erase hours-worked duties. When a state wage order is stricter than Fact Sheet #22 on restrictive on-call, document which rule you followed and keep the stricter pay. Managers should not borrow a quiet-season unpaid pattern from another industry when your logs show nightly pages.
§5Payroll walk-through example
Suppose a hospital tech is unpaid on-call from 7 p.m. to 7 a.m., must stay within fifteen minutes of campus, wear identifiable gear, and logs show three to five pages most nights. Under Fact Sheet #22, the on-premises or highly restricted pattern leans toward treating the entire waiting block as hours worked, not only the minutes on the phone. Pay the wait, pay the responses, and fold both into the overtime week.
Contrast a software engineer who keeps a laptop nearby, faces roughly one page a month, and may take the call from anywhere in the metro area. Leaving contact information alone usually keeps the idle wait unpaid; the call itself and any follow-on work still get paid. Put both examples in the handbook so managers stop copying one industry rule onto another.
When finance asks for a single rule of thumb, give them the table above instead. Restrictiveness is factual. A stipend labeled on-call pay does not automatically legalize unpaid waiting that fails the DOL test.
§6FAQ
Is carrying a phone enough to make on-call time paid?
Usually not, when the worker can still run personal errands and sleep on a normal schedule. Tight geography, uniforms, or minute-level response windows can flip that answer under the same DOL sheet.
Must we pay someone who waits at the job site between calls?
Yes. DOL guidance treats required on-premises waiting as compensable, even between pages.
Does payroll only need to clock the answered page?
Compensable minutes start when the worker begins responding. Idle waiting is a separate yes/no call based on the factors in the decision table.
Does a short lunch on call count as a meal break?
Not while the person must keep answering phones or monitoring systems. Cross-check the meal section of the federal hours-worked sheet and the lunch break guide.
