Under federal law, PTO does not count toward overtime. The 40-hour weekly threshold that triggers time-and-a-half pay is measured strictly in hours you actually worked, so vacation days, sick leave, holidays, and other paid absences show up on your paycheck without moving you closer to overtime. Your employer’s own policy or a union contract can be more generous and include PTO in the calculation, but nothing in federal law requires it.
Here is what that looks like on a real week. Say you take Monday off with eight hours of paid vacation and then work Tuesday through Friday for 35 hours. Your paycheck shows 43 paid hours, but your overtime calculation sees only 35 worked hours. No overtime is owed. Change the numbers so you work 42 hours and also use 8 hours of PTO, and you get 2 hours of overtime pay, not 10.
What Counts as an Hour Worked
The Fair Labor Standards Act requires non-exempt employees to be paid at least one and a half times their regular rate for every hour worked beyond 40 in a single workweek.1Office of the Law Revision Counsel. 29 USC 207 – Maximum Hours A workweek is any fixed, recurring block of 168 hours; it doesn’t have to match a calendar week, but once the employer sets the starting point, it stays put and cannot be shifted around to spread hours and dodge overtime.2eCFR. 29 CFR 778.105 – Determining the Workweek
“Hours worked” means time you are “suffered or permitted to work”—time you spend performing duties the employer controls, benefits from, or allows to happen.3eCFR. 29 CFR Part 785 – Hours Worked Sitting on a beach on a vacation day does not fit that definition. The regulations go further and address paid idle time directly: payments for absences due to vacation, holidays, illness, or similar causes are not compensation for hours of employment and are excluded from the overtime math entirely.4eCFR. 29 CFR 778.218 – Pay for Certain Idle Hours
When PTO Does Count Toward Overtime
Federal law sets the floor, not the ceiling. An employer is free to adopt a more generous rule that treats all paid hours—worked or not—as counting toward the 40-hour threshold. Once that policy appears in a handbook or written practice, it becomes a commitment the employer has to honor.
Union contracts often go this direction. Collective bargaining agreements commonly negotiate for holiday hours, personal days, or vacation time to count toward overtime. Under a contract like that, a worker who takes a paid holiday on Monday and works 36 hours the rest of the week hits 44 paid hours and picks up four hours of overtime pay. These provisions come from private negotiation and vary from one contract to the next; some count holiday hours but not sick days, some count PTO toward weekly overtime but not toward daily overtime in states that have it.
If you think your employer’s policy or your union agreement might include PTO, check the handbook or ask your union representative. Read the specific language, because a general reference to “paid hours” is not the same as a clause that spells out which categories are in.
Time That Counts as Worked Even Though It Doesn’t Feel Like It
PTO is clearly out, but several categories of time surprise people by counting as hours worked. If your employer excludes any of these, you may be owed overtime you did not realize was missing.
- Travel during the workday, such as driving between job sites or customer locations, is work time. So is travel to a one-day out-of-town assignment, minus your normal commute. Ordinary home-to-office commuting does not count.5U.S. Department of Labor. Fact Sheet 22 – Hours Worked Under the FLSA
- Overnight travel time counts when it falls during your normal working hours, even on days you would not normally work, like weekends.
- Mandatory training and meetings count if attendance is required, held during work hours, or directly related to your job. Training escapes the clock only if it is voluntary, outside normal hours, unrelated to your job, and you do no other work during it—all four conditions have to be true.
- On-call time at the workplace counts, even if you spend it reading between calls. On-call time from home is generally not compensable, though heavy restrictions on your freedom, like a two-minute response window, can change that answer.
These hours push you toward the 40-hour threshold the same way desk time does.
How PTO Affects the Overtime Pay Rate
There is a second question worth separating from the threshold question: even if PTO does not push you past 40 hours, does PTO pay affect the rate at which overtime is paid? It does not. Federal regulations exclude vacation pay, holiday pay, and similar idle-time payments from the “regular rate” used to calculate the overtime premium.6eCFR. 29 CFR 778.218 – Pay for Certain Idle Hours
What does fold into the regular rate might surprise you. Non-discretionary bonuses—production, attendance, and safety bonuses—and shift differentials have to be included when calculating the overtime rate, which means your overtime rate can run higher than 1.5 times your base wage. If you earn $15 an hour, work 45 hours in a week, get a $1 evening shift differential for 30 of those hours, and pick up a $100 production bonus, the regular rate for that week works out to roughly $17.89 per hour, and your overtime premium is calculated on that figure rather than on $15.7U.S. Department of Labor. Fact Sheet 56C – Bonuses Under the FLSA
State Daily Overtime Rules
A handful of states go beyond the federal 40-hour weekly threshold and require overtime on a daily basis. Workers in these states earn time-and-a-half after eight hours in a day (or after 12 hours, depending on the state), even if their weekly total stays under 40. Some also require double time for shifts running past 12 hours.
Daily overtime works the same way federal weekly overtime does for PTO purposes: only hours actually worked in a given day count toward the daily threshold. A paid holiday does not create an eight-hour “worked” block that then triggers daily overtime somewhere else in the week.
When state and federal rules overlap, the employer follows whichever is more favorable to the worker. Federal law says explicitly that no FLSA provision excuses noncompliance with a state law setting a shorter maximum workweek.8Office of the Law Revision Counsel. 29 USC 218 – Relation to Other Laws In practice, workers in daily-overtime states get both calculations, and the employer pays whichever total is larger.
If You Think Your Overtime Is Being Miscalculated
If your employer is shorting your overtime—whether by wrongly folding PTO into the worked-hours total to keep you under 40, miscounting travel or training time, or using some other method that cuts your pay—you can file a wage complaint with the Department of Labor’s Wage and Hour Division online or by phone at 1-866-487-9243. You will need your employer’s name and address, a description of your work, and details about how and when you are paid. The nearest field office will contact you within two business days to evaluate whether to investigate.9Worker.gov. Filing a Complaint With the Wage and Hour Division
An employer who violates the overtime rules owes the unpaid wages plus an equal amount in liquidated damages, effectively doubling the back pay.10GovInfo. 29 USC 216 – Penalties You generally have two years from each violation to file, or three years if the violation was willful.11Office of the Law Revision Counsel. 29 USC 255 – Statute of Limitations Each shorted paycheck starts its own clock, so older violations can drop off while you are still deciding what to do. Federal law also prohibits your employer from firing, demoting, or otherwise punishing you for filing a complaint or raising the issue internally.12U.S. Department of Labor.
