Under the Fair Labor Standards Act, hours worked covers every moment you are on duty, at a required location, or doing anything work-related that your employer knows about and allows. That is the core of what counts as hours worked under the FLSA: if the company suffers or permits the work, the time is compensable, even when nobody explicitly told you to do it.1Office of the Law Revision Counsel. 29 USC 203 – Definitions2eCFR. 29 CFR 785.11 – General Getting this right decides whether you are owed the federal minimum wage of $7.25 and overtime at one and a half times your regular rate for anything past 40 hours in a workweek.3Office of the Law Revision Counsel. 29 USC 207 – Maximum Hours
A written policy against unauthorized overtime does not change the answer. Your employer can discipline you for breaking the rule, but they still owe wages for hours they knew you worked. That is where most wage claims start: managers see the extra work, do not stop it, and later refuse to pay because it was not approved.
Who These Rules Apply To
The hours-worked rules matter if you are a non-exempt employee. The FLSA exempts bona fide executive, administrative, and professional workers from minimum wage and overtime.4Office of the Law Revision Counsel. 29 USC 213 – Exemptions To qualify for a white-collar exemption you generally must be paid on a salary basis of at least $684 per week and perform duties that fit one of the exemption tests.5U.S. Department of Labor. Fact Sheet 17A – Exemption for Executive, Administrative, Professional, Computer and Outside Sales Employees Under the FLSA If you fit an exemption, disputes over what counts as hours worked rarely reach you, because your employer is not required to track hours or pay overtime in the first place. Everything below is written for non-exempt workers.
Waiting and On-Call Time
Whether waiting counts turns on a single question: are you engaged to wait, or waiting to be engaged?6eCFR. 29 CFR 785.14 – General Sitting at your workstation between tasks, like a receptionist between calls or a firefighter between alarms, is engaged to wait. You cannot leave or do much of anything personal, so the time is paid.
On-call time at home is different. If you can leave a phone number and go about your life, the time is generally not compensable.7eCFR. 29 CFR 785.17 – On-Call Time The gray zone is a tightly restricted on-call arrangement: a short required response window, a small geographic radius, no alcohol or impairing medication. Courts look at how often you actually get called, how fast you must respond, and how much of your personal freedom is left. When the restrictions are heavy enough that you cannot really use the time for yourself, it can become compensable.
Sleep Time on 24-Hour Shifts
If you are on duty for 24 hours or more, up to eight hours of sleep can be excluded from paid time, but only when there is an agreement to exclude it, the employer provides adequate sleeping facilities, and you can usually get an uninterrupted night’s rest.8eCFR. 29 CFR 785.22 – Duty of 24 Hours or More Interruptions to answer calls are paid. If those interruptions are frequent enough that you cannot get at least five hours of sleep during the scheduled rest period, the entire sleep period becomes compensable.
Breaks and Meal Periods
Short breaks of roughly five to twenty minutes are paid. Federal regulations treat them as hours worked because they benefit the employer by keeping you productive, and your employer cannot dock a ten-minute coffee break.9eCFR. 29 CFR 785.18 – Rest
Meal periods work differently. A break of 30 minutes or more is unpaid only if you are completely relieved from duty for the whole period.10eCFR. 29 CFR 785.19 – Meal Eating at your desk while watching a phone line or a security feed does not qualify. The break is then a sham, and the full period is compensable.
Break Time for Nursing Employees
The PUMP for Nursing Mothers Act requires employers to provide reasonable break time to express breast milk for up to one year after a child’s birth, along with a private space that is not a bathroom.11U.S. Department of Labor. Fact Sheet 73 – FLSA Protections for Employees to Pump Breast Milk at Work Pumping breaks do not have to be paid if you are completely relieved from duty, but if your employer already provides paid breaks to other employees, a nursing employee using that same break time to pump must be paid on the same terms. Employers with fewer than 50 workers can claim an undue-hardship exemption.
Training, Meetings, and Lectures
Meetings, training sessions, and lectures count as hours worked unless all four of these are true: the event is outside your regular working hours, attendance is truly voluntary, the content is not directly related to your current job, and you do no productive work during the session.12eCFR. 29 CFR 785.27 – General Miss one and the time is paid.
Voluntary has teeth. If your manager hints that skipping will hurt your standing, or if missing it leads to a worse assignment or a poor review, it is not voluntary regardless of what the sign-up sheet says. Training that teaches skills for your current role is by definition directly related to your job, so it is compensable even after hours.
Travel Time
Your normal commute is not paid, whether you go to one fixed workplace or rotate between sites as part of your daily routine.13eCFR. 29 CFR 785.35 – Home to Work Ordinary Situation Commuting in an employer-provided vehicle usually follows the same rule so long as the trip stays within the normal commuting area and there is an agreement about the vehicle.14U.S. Department of Labor. Travel Time
Once the workday has started, travel between job sites is hours worked.15eCFR. 29 CFR 785.38 – Travel That Is All in the Days Work A plumber driving from a morning repair to an afternoon installation across town is on the clock for that drive.
One-Day Assignments in Another City
When you normally work at a fixed location but get sent to another city for the day, the travel is paid, minus your usual commute.16eCFR. 29 CFR 785.37 – Home to Work on Special One-Day Assignment in Another City If you normally drive 30 minutes to the office but instead drive two hours to a client site, the extra 90 minutes each way is compensable.
Overnight Trips
When travel keeps you away from home overnight, only travel that falls during your regular working hours is compensable, and that includes weekends and other days you do not normally work. If you usually work 9 a.m. to 5 p.m. Monday through Friday, a Saturday flight from noon to 4 p.m. is four hours of paid travel because it falls within those same hours.17eCFR. 29 CFR 785.39 – Travel Away From Home Community Travel outside those hours, like a red-eye when you never work nights, is generally not paid unless you are actually doing work during the trip.
Prep and Cleanup Before or After the Shift
The Portal-to-Portal Act excluded two categories of pre-shift and post-shift activity from hours worked: getting to and from your actual workstation, and tasks that are merely preliminary or postliminary to your main job.18Legal Information Institute. Portal-to-Portal Act Activities integral to your principal duties are still paid. Federal regulations give concrete examples: a lathe operator oiling and greasing a machine at the start of the day, a garment worker distributing materials to other benches before the shift, or a chemical plant worker putting on specialized protective clothing required for the job.19eCFR. 29 CFR 785.24 – Principles Noted in Portal-to-Portal Bulletin
Ask whether you can safely and effectively do your main job without the activity. If you cannot, the prep time counts. Routine steps like badging through a security gate or waiting in line at the time clock are treated as ordinary workplace access, not productive work.
Time Clock Rounding and De Minimis Time
Many employers round clock times to the nearest five, six, or fifteen minutes. Rounding is allowed, but only if it averages out over time so that employees are fully paid for the hours they actually work.20eCFR. 29 CFR 785.48 – Use of Time Clocks A system that consistently rounds down, always shaving minutes at the start of shifts but never adding them, fails that test.
The de minimis rule lets employers disregard truly trivial slivers of time that are practically impossible to record, on the order of seconds or a couple of minutes and occurring irregularly.21eCFR. 29 CFR 785.47 – De Minimis Rule Courts weigh how regularly the extra work happens, how much time it adds up to, and how hard it would be to track. A predictable five minutes of unpaid work every shift is not de minimis. That is more than 20 hours a year.
If Your Hours Are Not Being Counted Correctly
The Department of Labor’s Wage and Hour Division investigates FLSA complaints and can pursue back wages for you, and you can also file a private lawsuit. The filing deadline is two years from the violation, extended to three years if the violation was willful, meaning the employer knew it was breaking the law or showed reckless disregard.22Office of the Law Revision Counsel. 29 USC 255 – Statute of Limitations
An employee who wins an FLSA claim typically recovers the unpaid wages plus an equal amount in liquidated damages, doubling the payout. A court can reduce liquidated damages if the employer proves it acted in good faith with reasonable grounds to believe it was complying, but that is a hard showing.23Office of the Law Revision Counsel. 29 USC 260 – Liquidated Damages Keeping your own record of hours worked matters if you ever raise a claim. When an employer cannot produce accurate time records, courts tend to credit the employee’s account of the hours, so a contemporaneous log of start times, end times, breaks, and off-the-clock tasks is worth keeping.
