Sleep Time on a 24-Hour Shift: When You Get Paid for the Bunk Room and When You Don't

There's a question people with normal jobs ask 24-hour shift workers, and it sounds like small talk until you try to answer it: "So you were there for 24 hours — do you get paid for 24 hours?"

The honest answer is that it depends on things nobody mentions when you're hired. It depends on how long your tour is, down to the minute. It depends on whether there's a written agreement you may never have seen. And for firefighters and police officers it depends on which of two overtime systems your agency chose, which is a decision made in an office somewhere, possibly before you were hired.

Two people can sleep in the same bunk room on the same night and have that time counted differently. This is how that happens.

The starting point: being required to stay is being at work

Under the Fair Labor Standards Act, the default is that time you're required to spend on the employer's premises, on duty, counts as hours worked — even if you're allowed to sleep through part of it. Being permitted to sleep is not the same as being off.

For any tour of duty under 24 hours, that default is the whole story. The entire tour is hours worked, sleeping or not. There's no carve-out available. A 16-hour shift with a cot in the back room is 16 hours of work.

The rules only start to bend once a tour reaches 24 hours.

29 CFR 785.22: the general rule for 24 hours or more

For employees required to be on duty 24 hours or more, the employer and employee may agree to exclude from hours worked:

• bona fide meal periods, and
• a bona fide, regularly scheduled sleeping period of not more than 8 hours.

That exclusion isn't automatic, and it isn't the employer's to take unilaterally. Three conditions ride along with it:

1. There has to be an agreement — express or implied. The regulation is explicit that where no agreement to the contrary exists, the 8 hours of sleeping time and the meal periods are hours worked.
2. Adequate sleeping facilities have to be furnished by the employer.
3. You have to be able to usually enjoy an uninterrupted night's sleep.

And there's a ceiling: if the scheduled sleeping period is longer than 8 hours, only 8 can be credited as excluded. A 10-hour scheduled sleep block doesn't buy the employer 10 hours back.

That's the general rule. It's the one that applies to private ambulance services, private-sector residential and camp staff, and a lot of other round-the-clock arrangements.

Now the part that surprises people.

29 CFR 553.222: for fire and police, the boundary sits at exactly 24

Public agencies employing firefighters and police officers have a choice about how to compute overtime. They can use the ordinary weekly rule under section 7(a)(1), or they can elect the 7(k) work period — the public-safety provision that counts overtime over a 7-to-28-day period instead of a flat 40-hour week. (We wrote about that one separately in FLSA 7(k) explained.)

That choice — a choice about overtime accounting — turns out to also decide whether your sleep can be deducted.

If the agency has elected 7(k), sleep time cannot be excluded from compensable hours when:

• the tour of duty is less than 24 hours, or
• the tour of duty is exactly 24 hours.

The regulation itself flags the second one as "a departure from the general rules." Under the general rule in part 785, 24 hours is precisely where exclusion becomes possible. Under 7(k), 24 hours is the last point where it isn't.

Sleep time can be excluded for these employees only when the tour of duty is more than 24 hours — and even then, only if there's an express or implied agreement to do it. Absent an agreement, the sleep time is compensable. The cap is 8 hours in any 24-hour period.

If the agency instead pays overtime under 7(a)(1), the ordinary 785.22 conditions apply, and sleep time on a 24-hour tour can be excluded when those conditions are met.

Read those two paragraphs next to each other and you get the strange result at the center of this:

Two firefighters, two departments, the same 24-hour tour, the same bunk room, the same night — and one of them can have 8 hours taken out while the other can't. The variable isn't the shift. It's a box the employer checked about overtime accounting.

And on the same chart, notice what happens when a tour gets longer. A straight 24 at a 7(k) agency is 24 payable hours. Extend that to a 48 and the agency can now deduct up to 8 hours per 24-hour period, with an agreement in place. The longer tour can produce fewer payable hours per hour spent at the station than the shorter one.

There's a practical consequence of that boundary that's worth knowing about, because it shows up on real rosters. Since the exclusion only becomes available above 24 hours, departments that want to use it schedule tours that run slightly past the mark — a shift of 24 hours and 15 minutes, say, rather than a flat 24. Those extra minutes aren't an accident of shift change. They're the thing that puts the tour on the excludable side of the line.

So if your tour is posted as something like 07:00 to 07:20 the following day rather than 07:00 to 07:00, that's worth asking about. The odd ending time is usually the tell.

The interruption rules are where a busy night gets decided

If your sleep period is quiet, the arithmetic above is the whole picture. Most 24-hour shifts aren't quiet, and this is the part worth knowing precisely.

Every interruption counts. If the sleeping period is interrupted by a call to duty, the interruption is hours worked. Not rounded away, not absorbed into the excluded block — counted.

And past a certain point, the whole period flips. If the sleep period is interrupted to such an extent that you can't get a reasonable night's sleep, the entire period must be counted as hours of work. For enforcement purposes, the Department of Labor treats "a reasonable night's sleep" as at least 5 hours.

That threshold does a lot of quiet work. It means a night with two short runs and a night with six aren't just different in how tired you are — they can be categorically different in what the night is worth. Under 5 hours of sleep and the excluded block stops being excluded, all of it, not just the calls.

It also means the question "how many hours did I actually get?" is a payroll question and not only a personal one, which is not how most people are taught to think about it.

What this actually turns on, in order

If you're trying to work out where you stand, these are the questions in the order they matter:

1. How long is your tour, exactly? Under 24, at 24, or over 24 — these are three different legal categories, not points on a continuum.
2. Which overtime scheme does your employer use? For fire and police, 7(k) versus 7(a)(1) changes the answer at exactly 24 hours. This is usually findable — it's in the CBA, the personnel manual, or an ordinance.
3. Is there an agreement to exclude sleep time? Without one, sleep time is compensable even where exclusion would otherwise be allowed. It can be express or implied, so "I never signed anything" isn't the end of the inquiry, but it's a real question.
4. Are the sleeping facilities adequate, and can you usually get an uninterrupted night? These aren't decorative conditions. They're part of what makes the exclusion valid in the first place.
5. What actually happened last night? Interruptions are counted individually, and under 5 hours of sleep pulls the whole period back in.

A note on what this doesn't cover

This is the US federal floor. States can and do require more, and a collective bargaining agreement can be more generous than the regulation — it just can't go below it. If your contract says the whole 24 is paid, that governs, regardless of what the exclusion would have permitted.

There's also a separate rule for employees who reside on the employer's premises for extended periods, which works on a different logic than the tour-based rules here.

And this is a plain-language explanation of how the rules are structured, not legal advice about your situation. If the numbers on your check don't match what you'd expect from the above, the people who can actually answer it are your union rep, your payroll department, or your state labor agency.

The short version

Being asleep at work isn't automatically unpaid, and being awake isn't automatically paid — what governs is your tour length, your employer's overtime election, and whether an agreement exists. For 7(k) fire and police agencies, a tour of exactly 24 hours can't have sleep deducted at all. And on any tour where sleep can be deducted, a hard night takes the deduction back: every call counts, and less than 5 hours of sleep makes the whole period payable.

The number on the schedule says how long you'll be there. It doesn't say how many of those hours count. Those are two different numbers, and only one of them is posted.
