Comp Time vs Overtime Pay: What Federal Law Actually Allows
Private-sector employers cannot legally swap comp time for cash overtime, even if you agree to it. Only public-sector employers can, under strict FLSA limits. Here is how to tell the difference.
Compensatory time off, or comp time, is time off granted in exchange for overtime hours worked. Under federal law, private-sector employers cannot offer comp time instead of cash overtime pay, even if the employee agrees to it.
Only state and local government employers can substitute comp time for cash overtime, and only under specific FLSA conditions. If you work for a private company and your boss has been banking your overtime as future time off, there is a good chance you are owed money.
The private-sector rule: cash only
The FLSA requires that non-exempt private-sector employees be paid 1.5x their regular rate in cash for every overtime hour. An employee cannot waive this right, and an employer cannot ask them to.
A signed agreement accepting comp time in lieu of cash overtime in the private sector is void. The employee is still owed the overtime wages, and the waiver is unenforceable. If you are a private-sector hourly or non-exempt salaried worker and your employer offers comp time instead of overtime pay, that is a wage violation, full stop.
The public-sector exception
State and local government employers may offer comp time at a rate of 1.5 hours of time off for every overtime hour worked, under FLSA Section 207(o). A public-works employee who works 44 hours in a week earns 6 hours of comp time, that is 4 overtime hours times 1.5.
Conditions apply: the arrangement must be set up by agreement before the work is performed, comp time must accrue at the correct 1.5x rate, employees must be allowed to use accrued time within a reasonable period, and once an employee hits the cap, the employer must pay cash for further overtime.
The public-sector caps
The accrual caps are 240 hours of comp time for most public employees and 480 hours for public-safety officers, emergency responders, and seasonal workers. Once an employee exceeds the cap, any further overtime must be paid in cash.
Public employers also cannot unreasonably deny a request to use accrued comp time. If you are a government worker sitting on a large balance you can never seem to use, that may itself be a problem worth raising.
Flex time is not the same as comp time
Flex time, meaning adjusting hours within the same workweek, is legal for private employers. If you work 10 hours Monday but leave 2 hours early Friday, the workweek total stays at 40 and no overtime is owed.
The catch is that flex time only works inside the same seven-day workweek. An employer cannot ask you to work off last week's overtime by working fewer hours this week, because each workweek stands completely alone for FLSA overtime purposes. Confirm any borderline week in the overtime calculator.
Informal comp-time arrangements are still illegal
The most common form of illegal comp time is informal: a manager tells an hourly employee to take it easy next week because of the overtime they put in this week. Even with no formal policy, this violates the FLSA.
If the worker is ever audited or files a complaint, the employer faces back-wage liability for every underpaid week, plus liquidated damages equal to the unpaid overtime. Document any such arrangement, including who proposed it and when, because that record becomes evidence later.
What to do if you're offered comp time
If you are a private-sector non-exempt employee and your employer offers comp time instead of overtime, first calculate the cash you are owed with the overtime calculator. Then you have options: raise it with HR, send a demand letter, file a WHD complaint at dol.gov, or consult an attorney.
The violation accrues with each underpaid pay period, so the longer it continues, the larger the back-pay claim grows. There is no benefit to waiting, and the statute of limitations is steadily working against you.
Frequently asked questions
Can I agree to comp time if I prefer time off? In the private sector, no. Your agreement does not make it legal, and you remain owed the cash overtime. In the public sector, a proper agreement made before the work can allow comp time.
What if my private employer has done this for years? Each underpaid week is its own violation. You can generally reach back two years, three if willful, plus liquidated damages. See the statute of limitations on unpaid wages.
Is a four-day, 40-hour week with a long day overtime? Not under federal law if total worked hours stay at or under 40 in the week. But in daily-overtime states like California, hours over 8 in a day can trigger overtime regardless of the weekly total.
Convert your comp time to a number
If your overtime has been disappearing into a comp-time bank, the first step is to translate those banked hours into the cash the law actually requires. That number is usually larger than the time-off you were offered.
Run your overtime hours through the overtime calculator to see the cash value, then decide how to pursue it. This is general information, not legal advice, but for private-sector workers, comp time in place of overtime is one of the clearer violations to act on.
