Under federal law, most hourly workers who put in more than 40 hours in a week are owed extra pay, and plenty never collect it. Non-exempt employees must be paid time-and-a-half for those overtime hours, one of the oldest worker protections on the books and also one of the most commonly shortchanged. Knowing the rule is the first step to catching when it is being broken.
The basic rule
The Fair Labor Standards Act requires employers to pay covered, non-exempt workers overtime of at least one and a half times their regular rate for hours worked over 40 in a single workweek. If someone earning $16 an hour works 45 hours, the five extra hours must be paid at $24 an hour, not $16.
The threshold is weekly, not daily, under federal law. Working ten hours in one day does not by itself trigger overtime; it is the total past 40 across the seven-day workweek that counts. Some states add daily overtime rules on top of the federal standard, but the federal floor is the 40-hour week.

Who is covered and who is not
Most hourly workers are non-exempt, meaning the overtime rule applies to them. Exemptions generally cover certain salaried employees in executive, administrative, and professional roles who earn above a set salary threshold and whose duties meet specific tests. Being paid a salary alone does not make a worker exempt; the job duties and pay level both have to qualify.
This distinction is where a lot of unpaid overtime hides. An employer cannot escape the overtime rule simply by calling a worker a manager or putting them on salary if the actual duties and pay do not meet the exemption tests. Workers who are unsure of their status can review the standards on the Department of Labor site.
The salary threshold matters too. A salaried employee whose pay falls below the exemption’s minimum dollar level is generally entitled to overtime regardless of job title, so a low-paid assistant manager working sixty-hour weeks may well be owed time-and-a-half. Job title alone never settles the question; the pay level and the day-to-day duties do.
The regular rate is more than the base wage
Overtime is calculated on the regular rate, which is not always just the hourly wage. Nondiscretionary bonuses, shift differentials, and certain other forms of pay have to be folded into the regular rate before the time-and-a-half is figured. That means a production bonus can actually raise the overtime rate owed.
Employers sometimes get this wrong by computing overtime only on the base hourly figure and ignoring the add-ons. For a worker who regularly earns bonuses or premiums, the difference over a year can be real money, and it is money the law says is owed.
Common ways workers get shortchanged
Beyond misclassification, unpaid overtime shows up in familiar patterns: being asked to work off the clock before or after a shift, having hours shaved during meal breaks that were actually worked, or being paid straight time for overtime hours. Averaging hours across two weeks to keep a single week under 40 is also not allowed under federal law; each workweek stands on its own.
None of these practices become legal because a worker agreed to them or a supervisor asked. The right to overtime cannot be waived, so an employee who worked the hours is owed the pay regardless of any informal understanding.
How to claim what you are owed
A worker who believes they were denied overtime can file a confidential complaint with the Department of Labor’s Wage and Hour Division, which investigates and can recover back wages, as the agency explains in its FLSA materials. It is free to file, and the law prohibits an employer from retaliating against a worker for asserting these rights.
Keeping a personal record of hours worked, separate from the employer’s timekeeping, is the single best protection. When a dispute arises, a worker’s own contemporaneous log of start and end times is powerful evidence, and it often makes the difference between a shrug and a recovery of unpaid wages.
What overtime is worth over a year
The stakes are larger than a single paycheck suggests. Consider a worker earning $18 an hour who regularly puts in five hours of overtime a week. Paid correctly at time-and-a-half, those hours are worth $27 each, or $135 a week, which comes to roughly $7,000 over a year. Paid incorrectly at straight time, the same hours yield $90 a week, and the worker quietly loses about $2,300 a year to a mistake that may never appear on a pay stub as an error.
Multiply that across the misclassification and off-the-clock patterns described above, and it becomes clear why overtime enforcement is one of the largest sources of recovered back wages the Labor Department reports each year. This is not a technicality; it is often thousands of dollars a household is legally owed.
That is also why the recordkeeping habit pays off so directly. A worker who can show the hours actually worked, week by week, is in a strong position to recover the difference, and the law’s anti-retaliation protection means asserting the right should not cost the job. For most hourly workers, understanding the 40-hour rule is one of the highest-return pieces of financial knowledge they can carry.
