A covered, nonexempt employee who works 50 hours in one workweek generally earns 10 hours of overtime, even if the next week contains only 30 hours. Federal law treats each workweek separately and does not let an employer average the two weeks into 40 hours apiece. Payroll schedules can group weeks on one check, but they cannot erase overtime already earned.
The legal unit is a fixed 168-hour workweek
The Fair Labor Standards Act defines the workweek as a fixed, regularly recurring period of 168 hours: seven consecutive 24-hour periods. It can begin on any day and at any hour chosen by the employer, and different groups of employees may have different workweeks. Once established, however, the boundary cannot be shifted back and forth to avoid overtime.
The Labor Department’s overtime fact sheet says covered, nonexempt workers must receive at least one and one-half times their regular rate for hours over 40 in a workweek. It states directly that averaging hours over two or more weeks is not permitted.

A two-week paycheck can hide the calculation
Biweekly payroll is common, but the pay period does not replace the workweek. Suppose an employee works 50 hours in week one and 30 in week two. The check may display 80 total hours, yet federal overtime is calculated as 40 straight-time hours plus 10 overtime hours in the first week and 30 straight-time hours in the second.
The same rule applies when a busy week is followed by approved leave, a holiday or a scheduling cut. An employer can reduce future hours prospectively, but the reduction does not retroactively convert overtime hours into straight time. Pay records should show how each workweek was treated, even when one paycheck covers several weeks.
The regular rate can include more than hourly wages
Time-and-a-half is based on the regular rate, which can include certain nondiscretionary bonuses, commissions, shift differentials and other compensation. It is not always identical to the base hourly rate printed on a schedule. Payments excluded by law, such as some expense reimbursements or truly discretionary bonuses, are treated differently.
DOL’s regular-rate guidance describes which payments generally enter the calculation. A worker who receives production bonuses or incentives should check whether payroll allocated them across the weeks in which they were earned and recalculated overtime accordingly.
Not every employee is covered in the same way
The federal rule applies to covered, nonexempt employees. Properly exempt executive, administrative, professional and outside sales workers follow different standards, as do some employees under specific industry exemptions. Public agencies may use compensatory time in circumstances that do not apply to ordinary private employers.
State law may require overtime sooner, such as after a certain number of hours in a day, or may cover workers excluded by federal law. The Labor Department’s overtime overview notes that when both state and federal rules apply, the employee receives the higher protection. The 40-hour federal standard is a floor, not a ceiling on state rights.
Off-the-clock work belongs in the weekly total
Required work performed before clock-in, after clock-out or during an interrupted unpaid meal period can affect whether the total crosses 40. Answering job emails, preparing equipment or closing a register may count when the employer knows or has reason to know the work is being done. A policy forbidding unauthorized overtime does not permit the employer to accept the work without paying for it.
Employees should preserve schedules, time punches, messages and their own contemporaneous notes. A personal log is especially useful when a timekeeping system automatically deducts meal breaks or rounds punches. Questions can be directed to the Wage and Hour Division, and retaliation for asserting FLSA rights is separately prohibited.
Week-by-week math protects the overtime premium
Averaging would let a quiet week cancel the premium intended for a long one. Congress structured overtime around the individual workweek so employers face a higher cost when covered employees work beyond 40 hours and workers receive extra compensation for that burden.
The controlling DOL fact sheet leaves no ambiguity about the 50-hour example: overtime earned in that first workweek remains due, regardless of a shorter second week. The right questions are whether the worker is covered and nonexempt, what hours count as work and what compensation enters the regular rate—not whether the two-week total happens to average 40.
A pay stub that shows 80 straight-time hours across those two weeks should therefore be reviewed against the daily time record. The combined total can look correct while the legally required premium for the first week’s 10 overtime hours is missing.
