Under federal law, PTO hours do not count toward overtime. The Fair Labor Standards Act only requires time-and-a-half once you physically work more than 40 hours in a workweek, and paid time off for vacation, holidays, sick leave, or jury duty is not “hours worked” no matter how it shows up on your pay stub.1eCFR. 29 CFR 778.218 – Pay for Certain Idle Hours Your employer can choose to be more generous, and some do — through a handbook policy or a union contract — but the FLSA itself sets the floor at hours actually worked.
The 40-Hour Rule and What Counts as Hours Worked
The FLSA requires employers to pay non-exempt employees at least one and one-half times their regular hourly rate for every hour worked beyond 40 in a single workweek.2Office of the Law Revision Counsel. 29 USC 207 – Maximum Hours A workweek is a fixed, recurring block of 168 hours — seven consecutive 24-hour periods — and the employer picks when it starts.3eCFR. 29 CFR 778.105 – Determining the Workweek There is no federal daily overtime requirement. Only the weekly total counts.
Federal regulations draw a hard line between time on the job and time simply being paid. Under 29 CFR 778.218, payments for periods when you aren’t working — vacation, holidays, sick leave, jury duty, and similar absences — are not compensation for hours of employment.1eCFR. 29 CFR 778.218 – Pay for Certain Idle Hours Those payments are excluded from the regular rate calculation entirely, and no part of them can be credited toward overtime you’re owed.
The result is the same regardless of the circumstances. Whether you requested the day, your boss sent you home, or the office closed for a holiday, those hours don’t push you past 40. One nuance worth flagging: the rule covers occasional or infrequent absences. A regularly scheduled day off is not a holiday just because the office is closed, and the regulation specifically excludes routine rest days from this category.
What This Looks Like on a Paycheck
Say you earn $20 per hour. You work Monday through Thursday for 35 hours, then take Friday off using 10 hours of PTO. Your pay stub shows 45 hours of pay, but only 35 of those are hours worked under the FLSA. Since 35 is below 40, your employer owes straight time for every hour: 45 × $20 = $900.
Change the scenario. You work 45 actual hours and use no PTO. The first 40 pay $20; the last 5 pay $30. Gross jumps to $950. The $50 difference is the overtime premium PTO does not create.
Here’s where the math gets useful. Suppose you work 38 hours, use 8 hours of PTO, then come in Saturday for 6 more hours. Total paid hours: 52. Hours worked: 44. Four of those hours qualify for overtime, because the PTO is irrelevant to the overtime trigger.4eCFR. Part 778 – Overtime Compensation Only the 44 physically worked hours matter.
When Your Employer or Union Counts PTO Anyway
Federal law sets a floor, not a ceiling. Employers can adopt policies more generous than the FLSA requires, and many do. A company handbook might state that all paid hours, including PTO, count toward the 40-hour overtime trigger. Union contracts often negotiate this treatment, particularly in industries with irregular schedules where members mix leave days with long shifts.
Once an employer puts this in writing, it becomes enforceable. If the handbook says PTO counts and payroll ignores that promise, the employee has a breach-of-contract claim. That’s a private contractual dispute, not an FLSA violation, but it’s still money owed. Read your handbook. If a union represents you, check the collective bargaining agreement. The answer for your specific job may already be spelled out.
Unauthorized Overtime Still Has to Be Paid
Common situation: you take a PTO day Monday, then work long hours Tuesday through Saturday to cover a deadline, and your boss says the extra hours “don’t count” because you weren’t authorized to work them. That’s wrong. The FLSA does not care whether overtime was pre-approved. If you physically performed the work and exceeded 40 hours worked, the employer must pay the overtime rate.5U.S. Department of Labor Wage and Hour Division. Fact Sheet #23 – Overtime Pay Requirements of the FLSA
An employer can discipline you for working unauthorized hours. They cannot withhold the pay. An announcement that “overtime won’t be paid unless authorized in advance” doesn’t eliminate the legal obligation.5U.S. Department of Labor Wage and Hour Division. Fact Sheet #23 – Overtime Pay Requirements of the FLSA This is one of the areas where employers trip up most often during Wage and Hour Division investigations.
State Daily Overtime Rules
The FLSA measures overtime weekly, but a handful of states also require overtime for long individual days. A few states mandate time and a half after 8 hours in a single day, and at least one requires double time after 12 hours. Where daily overtime applies, it counts hours actually worked that day. PTO earlier in the week is irrelevant. You could trigger premium pay on a 10-hour Tuesday even if you took Monday off and only worked 34 hours all week. Check your state labor department, since these rules vary significantly.
Checking the Math and Fixing an Underpayment
Employers must track hours worked per day and per week for every non-exempt employee, and retain payroll records for at least three years.6eCFR. Part 516 – Records to Be Kept by Employers Time records that determine earnings must be kept at least two years. Those records are what separate hours physically worked from PTO hours on your pay stub.
If you suspect your employer is miscounting PTO as hours worked — or, more commonly, failing to pay overtime on hours you actually worked — request copies of your time records. Keep your own log too. A notebook or spreadsheet with dates and times is enough.
An employer who miscalculates and underpays overtime owes the unpaid wages plus an equal amount in liquidated damages, effectively doubling what’s owed, along with reasonable attorney’s fees.7Office of the Law Revision Counsel. 29 USC 216 – Penalties You have two years from each underpayment to file a claim, or three years if the violation was willful, meaning the employer knew the law and disregarded it.8Office of the Law Revision Counsel. 29 USC 255 – Statute of Limitations Claims can go to the Department of Labor’s Wage and Hour Division or directly to federal or state court. Once the DOL files on your behalf, your individual right to sue on the same claim ends. The clock runs separately for each paycheck, so older weeks may be gone while recent ones are still recoverable.
