Federal Child Labor Baseline Rules
Before you schedule a single shift for a high school student, you need to understand the federal floor that applies to every minor hire in the United States. The Fair Labor Standards Act (FLSA) sets three core limits: how many hours a minor can work, when those hours can fall, and which jobs are categorically forbidden. These rules apply nationwide, regardless of where your business operates, though most states add stricter protections on top.
For workers under age 16. The FLSA caps school-day shifts at 3 hours per day and limits the school week to 18 hours total. On non-school days—weekends, holidays, and summer break—those minors can work up to 8 hours per day and 40 hours per week. Night work is restricted too: minors under 16 may not work past 7 p.m. during the school year or past 9 p.m. between June 1 and Labor Day. Workers age 16 or 17 face no federal hour limits but are still barred from hazardous occupations.
All student hires must earn at least the federal minimum wage of $7.25 per hour (as of 2026), though many states set higher floors. The FLSA also prohibits anyone under 18 from working in specific hazardous industries: mining, roofing, logging, operating power-driven machinery, manufacturing explosives, and meat processing, among others. Violating these restrictions triggers steep fines and can disqualify you from hiring minors in the future.
Most states layer additional hour caps, earlier night-work cutoffs, or expanded hazardous-job lists onto the federal baseline. Understanding where your state's rules diverge from the FLSA is the next compliance step.
State Hour Limits & Hazardous-Job Bans
Federal child labor rules set the floor, but your state's labor department often builds a tighter ceiling on top. When state law imposes stricter hour limits, night-work cutoffs, or hazardous-job restrictions, those rules control—and most HR compliance mistakes happen when teams assume federal standards are enough. Before you schedule the first shift for a teen hire, identify your state's labor board website and cross-reference its current rules.
California applies strict school-night protections: 14- and 15-year-olds may work only until 7 p.m. during the school year, tightening the federal 7 p.m. standard, and caps total hours at 18 per school week. New York bars minors under 18 from working past 10 p.m. before a school day, narrows the workday window to eight hours, and requires a written employment certificate before the first shift. Texas carves out agricultural exemptions but adds a four-consecutive-hour cap on school days for 14- and 15-year-old workers. Each of these states extends federal hazardous-job lists: California adds bakery work and power-driven machinery; New York includes door-to-door sales.
A common violation: scheduling a 15-year-old six days per week during the school year in a state that caps school-week work at four days. In one documented case, a restaurant chain paid five-figure penalties after rostering minors past state night-work curfews for three consecutive months. The employer had consulted only the federal poster and missed the state addendum posted beside it.
Pre-Hire Compliance Checklist
Identify your state labor department's child-labor page. Download the current hour chart and hazardous-occupation list. Confirm whether your state requires work permits or employment certificates. Cross-check shift times and weekly hour totals against both federal and state caps. Document these rules in your onboarding file before the minor's first day. When state law sets a tighter standard, that standard governs—and ignorance of the state rule does not reduce the fine.
Student Worker Minimum Wage & Payroll Setup
Federal minimum wage establishes a baseline compensation requirement, but your obligation is to pay whichever rate is higher — federal or state. Many states set minimums above the federal floor, and some cities layer on an additional tier. Federal law permits a reduced training wage for workers under 20 during their initial employment period, but only when state law allows it; several states prohibit this subminimum entirely, so check your state labor department guidance before applying it.
Tipped positions — such as restaurant counter service or delivery — follow separate rules. Federal law allows employers to pay a reduced cash wage if employee tips bring total compensation to the full minimum wage threshold; if tips fall short, you cover the gap. Many states require a higher cash wage or prohibit tip credits altogether. Misclassifying a student server as fully tipped when your state forbids the credit creates instant back-pay liability.
Classification mistakes are common with student workers. Most students are non-exempt hourly employees under the Fair Labor Standards Act, meaning they must receive overtime pay at 1.5 times their regular rate for hours worked beyond 40 in a workweek. Unless the role meets strict salary and duties tests for exemption — which part-time clerical or service jobs rarely do — treating a student as exempt will trigger wage violations and penalties.
Payroll record-keeping for minors requires meticulous hour logs. Use time-tracking software that flags when a minor approaches daily or weekly caps, and keep student payroll separate from adult runs so pre-hire work permits and age certificates stay linked to the correct records. Run a pre-summer audit to confirm every student is classified correctly, has an active work permit on file where required, and is enrolled in the right pay schedule. This audit catches misclassifications before the first check goes out and keeps your payroll defensible during a state labor inspection.
Pre-Hire & Schedule Compliance Checklist
Pre-Hire Documentation
Before a student's first shift, your documentation stack should answer three questions: Can they legally work? Do state rules require additional permits? Have we secured parental sign-off where required? Start with proof of age. A copy of a birth certificate, driver's license, or state-issued ID establishes the employee's date of birth and determines which hour caps and hazardous-job bans apply.
Next, verify whether your state requires a work permit (sometimes called an employment certificate). States including California, New York, and Massachusetts mandate permits for minors, issued by the school district or labor department, before any work begins. The permit typically requires a school official's signature, proof of age, and a job-offer letter listing hours and duties. If your state requires parental consent in writing, collect that before onboarding—often bundled into the work-permit application itself.
Keep copies in the employee's personnel file. During a wage-and-hour audit, inspectors ask for these documents first. Missing or incomplete permits trigger fines even when the scheduling itself complies with hour limits.
Schedule Audit & Build
Once documents clear, map the schedule against state and federal hour caps before you post the job. Build a four-week pre-hire timeline: Week 1: Confirm your state's school-week and non-school-week hour limits. Week 2: Collect work permits and parental consent forms. Week 3: Draft the student's proposed schedule, counting total hours per day and per week. Week 4: Run the compliance audit—flag any day over the daily cap, any week over the weekly cap, and any shift ending past the night-work cutoff.
Here's a sample summer schedule for a 15-year-old in a state with an eight-hour daily cap and 40-hour weekly cap: Monday through Friday, 9 a.m. to 5 p.m. (eight hours each day, 40 total). That passes. Now layer in a Saturday shift, 10 a.m. to 2 p.m. (four hours). Total weekly hours: 44. Red flag. The week violates the 40-hour cap. Restructure by shortening one weekday shift to six hours, bringing the week back to 38.
Run the same audit before fall hiring, when school-week caps drop. A 15-year-old may work only 18 hours per week during the school year in many states—three hours per school day, eight on weekends. A schedule showing four-hour weekday shifts immediately violates the daily cap. Catch these violations on paper, before the employee clocks in and the liability starts.
Pre-Hire Documentation
Before a student's first day, your HR file must contain proof of age—a driver's license, birth certificate, or passport—kept on record for every hire under 18. Many states require a formal work permit, issued by the student's school or state labor board, which must be approved and filed before the start date. Check your state labor department website to confirm permit requirements in your jurisdiction.
If your state mandates parental consent for minors under 16 or 18, collect a signed consent form at the same time you request age verification. Request all documents at least two to three weeks before the scheduled start date, giving families time to visit the school office or labor board if a permit application is required.
PayDayPuffin. Payroll stores compliance documents in employee records, so copies of permits, consent forms, and age verification stay attached to the hire file and ready for audit. Missing even one document can trigger fines during a labor inspection, so treat the pre-hire checklist as a non-negotiable step in every student onboarding cycle.
Schedule Audit & Build
Picture a 15-year-old hired for your summer rush. Federal law allows eight hours per day and 40 per week during non-school periods. You schedule Monday through Friday, eight hours each: that's 40 hours, compliant. Now add a four-hour Saturday shift. You've hit 44 hours and triggered a violation before the first check runs.
Here's the fix: cap the week at 40 by shortening one weekday shift to six hours, leaving room for that Saturday. During fall semester, the same student faces school-day caps—three hours Monday through Friday when classes run, eight on Saturday and Sunday. A compliant week might be three hours Tuesday and Thursday (six total), plus two eight-hour weekend shifts (16 more), for 22 weekly hours.
Build a one-column audit spreadsheet: student name, date, shift start and end, daily total, weekly running count. Before you post the schedule, scan the weekly-total column. Any cell over your state cap turns red, triggering a restructure before onboarding begins.
Hazardous Jobs & Role Restrictions
The Fair Labor Standards Act identifies 17 hazardous occupations that workers under 18 cannot perform under any circumstances. The list includes mining, roofing, operating power-driven hoisting apparatus, and working with most power-driven machinery. For summer hires in construction, landscaping, or warehouse roles, these bans eliminate tasks like driving a forklift, climbing scaffolding to install gutters, or operating a commercial dough mixer. Parents cannot waive these restrictions, and students cannot volunteer for banned work—federal law treats hazardous-occupation rules as non-negotiable compliance lines.
Many states expand the federal list with additional prohibitions. California bans minors from operating power-driven lawn mowers and trimmers, narrowing what a landscaping crew can legally assign to a 17-year-old summer hire. New York prohibits minors from using slicing machines in food prep, affecting delis and cafés that might otherwise schedule a student to slice cold cuts. Before you post a summer job description, cross-check each task against both the federal hazardous-occupation list and your state labor department's additional bans. If the role includes equipment operation, material handling above six feet, or exposure to chemicals, flag it for review.
In 2021, the Department of Labor assessed more than ten thousand dollars in penalties against a small roofing contractor who assigned a 16-year-old to tear off shingles and carry materials on a residential roof. The employer argued the teen had parental permission and prior construction experience. The DOL rejected both defenses—roofing is a per-se violation for anyone under 18. The fine covered back wages, penalties, and the cost of reinvestigating the contractor's entire workforce. For more on the compliance stakes, see our payroll-compliance-mistakes guide.
When you build a job description for student hires, write down every task the role requires, then audit that list against hazard restrictions before you interview candidates. If a task appears on the banned list, remove it from the role or reassign it to an adult employee. This pre-hire review keeps you out of violation territory and protects the students you bring on board.
Next Steps: Compliance & Retention
You have your state rules, you know the hazardous-job bans, and you understand the federal baseline. Now map those rules to a calendar before you post a single shift. Week 1: Confirm your state's hour caps, night-work cutoffs, and work-permit requirements. Print or bookmark the labor department page and save it to your compliance folder. Week 2: Finalize job descriptions and duties—if a task touches a hazardous occupation, remove it or reserve that role for adults. Week 3: Request proof of age, work permits, and parental consent forms. Give applicants a two-week window to submit documents before the first day. Week 4: Build your draft schedule, count weekly hours against federal and state caps, and adjust shifts to close any violations before you post schedules.
Once students start working, compliance does not pause. Track hours in real time, and revise schedules if the school calendar shifts—a holiday moves, exams begin early, or a term ends. Retention improves when young workers understand their schedule and receive correct wages on the first payday. Predictability matters, and so does getting paid right. Compliance is not a legal burden; it is how you keep good hires.
Keep a one-page summary of your state rules and the federal baseline in every new-hire folder or employee handbook. If a question arises that your state labor department cannot answer, consult employment counsel before making the scheduling decision. For audit readiness, store work permits, age certificates, and signed parental consent forms in each employee's file, alongside your weekly hour logs.
