Under federal law, a 16-year-old can work an unlimited number of hours in any non-hazardous job. Most states, though, set their own caps that limit daily and weekly hours during the school year and loosen them during breaks, so how many hours a 16-year-old can work in practice depends almost entirely on the state and whether school is in session.
What Federal Law Says
The Fair Labor Standards Act treats 16 as the age when hour restrictions drop away. Workers who are 14 and 15 face strict federal limits: three hours on a school day, 18 hours in a school week, eight hours on a non-school day, and 40 hours in a non-school week. At 16, all of those federal caps disappear.1U.S. Department of Labor. Child Labor Provisions of the Fair Labor Standards Act for Nonagricultural Occupations A 16-year-old can legally work a 40-hour week, back-to-back shifts, or seven days straight as far as the federal government is concerned.
What federal law still restricts at 16 is the type of work, not the amount. The Department of Labor bans anyone under 18 from 17 categories of hazardous occupations, including most driving jobs, roofing, excavation, operating power-driven meat or bakery equipment, and running forklifts or other hoisting gear.2eCFR. 29 CFR Part 570 – Child Labor Regulations, Orders and Statements Those bans apply no matter how few hours you work. But once the job itself is legal, federal law is silent on how long the shift can be.
State Law Is What Actually Governs Your Schedule
Because the federal cap is effectively unlimited, any state rule that sets a lower ceiling wins. When federal and state child labor standards differ, employers must follow whichever is more protective of the worker.3U.S. Department of Labor. YouthRules For a 16-year-old, that almost always means the state rule.
A small number of states track the federal approach and impose no hour restrictions on 16-year-olds. The majority set daily and weekly limits that tighten during the school year and relax when school is out. Because the numbers vary from state to state, the Department of Labor’s comparison chart of state child labor standards is the fastest way to see exactly what applies where you live.4U.S. Department of Labor.

Hours Allowed During the School Year
During the school year, state restrictions tighten to keep work from crowding out class. A common pattern is a three- or four-hour daily limit on school days, with weekly caps generally falling somewhere between 18 and 28 hours.4U.S. Department of Labor. Selected State Child Labor Standards Affecting Minors Under 18 in Non-farm Employment Some states go lower, capping the week at 15 hours; others allow 30 or more when a student has parental permission and passing grades.
Remote school counts. The Department of Labor has clarified that school is considered “in session” during any week students are required to participate in distance learning, so a virtual-school week carries the same hour restrictions as an in-person one. Required summer sessions count too.
Homeschooled students sit in a gray zone. Some states exempt homeschooled minors from school-day hour caps, and others treat homeschool days like any other school day. If you’re homeschooled and looking at a job, the exact wording of your state’s rule is worth checking before you accept a schedule.
Hours Allowed During Summer and School Breaks
When school is out, the caps widen. The typical pattern across states is an eight-hour daily maximum and a 40-hour weekly cap during summer, spring, and winter breaks, essentially matching an adult full-time schedule. Some states go higher, allowing 48 or even 50 hours in a break week, and several permit 10-hour days.4U.S. Department of Labor. Selected State Child Labor Standards Affecting Minors Under 18 in Non-farm Employment
A “non-school week” generally has to be a full calendar week clear of classes, not just a stretch of days when you happen to be off. A week with even one scheduled school day usually still counts as a school week for purposes of the tighter limits.
Nighttime Curfews
Total hours are only half the picture. Most states also restrict when a 16-year-old can be on the clock. On nights before a school day, the shift usually has to end by 10:00 PM or 11:00 PM. On weekends and nights before a non-school day, the cutoff often stretches to midnight.4U.S. Department of Labor. Selected State Child Labor Standards Affecting Minors Under 18 in Non-farm Employment
Morning starts are limited too. Many states prohibit shifts from beginning before 6:00 AM or 7:00 AM. If you’re considering an early stocking shift or a late restaurant close, the time-of-day rules can bind before the total-hours rules do.
Overtime Once Your Hours Climb
Overtime works the same for a 16-year-old as for an adult under federal law. If you’re a covered, non-exempt employee working more than 40 hours in a week, your employer owes you time-and-a-half for every hour past 40.5U.S. Department of Labor. Wages and the Fair Labor Standards Act Because most states cap a 16-year-old below 40 hours during the school year, overtime usually becomes relevant only during summer and other school breaks in states that permit longer workweeks.
Farm Work Follows Different Rules
Agricultural jobs sit under a separate federal framework. There are no federal hour limits for farm work at 16, and the hazardous-occupation restrictions in agriculture are aimed mainly at workers under 16 rather than under 18.6U.S. Department of Labor. Agricultural Employment Under the Fair Labor Standards Act Minors of any age working on a farm owned or operated by their parents are largely exempt from federal child labor rules entirely. States can still impose their own agricultural hour limits and machinery restrictions, so a summer farm job isn’t automatically unregulated where you live.
How to Check Your State and What to Do if Your Employer Ignores the Limits
The reliable place to look up your state’s exact numbers is the state labor department’s website, or the Department of Labor’s state-by-state comparison chart for minors.4U.S. Department of Labor. Selected State Child Labor Standards Affecting Minors Under 18 in Non-farm Employment Look specifically for daily maximum, weekly maximum, school-in-session rules, and night-work cutoffs.
Enforcement falls on the employer, not on you. A 16-year-old won’t be fined for working too many hours; the employer bears the liability, and federal civil penalties can reach $16,035 per affected worker per violation, with higher penalties when a violation causes serious injury or death.7eCFR. 29 CFR Part 579 – Child Labor Violations—Civil Money Penalties If your schedule is running past the legal cap, you can file a complaint with your state labor department or the federal Wage and Hour Division. Both accept complaints without disclosing your name to the employer. Keep your own log of shifts, even a running note on your phone, so you have concrete hours to point to if the issue ever needs to be sorted out.
