Child Labor Laws in Missouri: Youth Employment Rules

The Fair Labor Standards Act (FLSA), 29 U.S.C. § 203 et seq., establishes a federal framework for child labor in the United States. The FLSA prohibits employment of children under 14 in most non-agricultural occupations and restricts hours of work for minors aged 14–15 to 3 hours on school days, 8 hours on non-school days, and 40 hours per week during the school year. The federal law identifies hazardous occupations in which no minor under 16 may work, including those involving mining, logging, exposure to radioactive materials, and operation of heavy machinery.

Federal youth minimum wage matches the minimum wage applicable to adults—currently $7.25 per hour—though states may establish higher youth minimum wages. The U.S. Department of Labor (DOL) administers and enforces federal child labor standards. Employers covered by the FLSA (those affecting interstate commerce with annual gross sales of at least $500,000, or smaller employers engaged in specific industries) must comply with both federal and state child labor restrictions. The federal law permits limited exemptions for family businesses and agricultural work, though state laws may impose stricter requirements.

Missouri's child labor laws, codified in Missouri Revised Statutes § 294.010 et seq., are generally aligned with federal FLSA standards but include state-specific provisions. Under Missouri law, no minor under 14 years of age may be employed except in agricultural work, domestic service, or work in a business wholly owned by their parents or guardians. This is more restrictive than some other states that permit limited exceptions at younger ages.

Missouri's work hour restrictions for minors aged 14–15 mirror federal limits: minors may not work more than 3 hours on school days, 8 hours on non-school days, and 40 hours per week during the school year. There is no specific Saturday restriction, and minors may work longer hours during school vacation periods, subject to the daily and weekly caps. Missouri prohibits minors from working between 10 p.m. and 5 a.m., except in certain occupations such as newspapers and agricultural work, which have different hour rules.

Missouri's minimum wage applies equally to youth: as of January 1, 2024, the state minimum wage is $11.15 per hour. This means Missouri youth workers earn $11.15 per hour—higher than the federal youth minimum wage of $7.25. Missouri law prohibits child labor in hazardous occupations, with prohibited jobs including mining, logging, roofing, operation of power-driven machinery, meat packing, and exposure to radioactive materials.

Missouri requires employers to maintain proof of age documentation for all minors, typically a birth certificate, passport, or school record. Employers must also maintain a record of each minor's hours worked. Violations can result in civil penalties; the Missouri Department of Labor may assess penalties up to $5,000 per violation. Missouri's law covers private-sector employers but does not apply to federal, state, or local government agencies in the same manner.

Missouri's child labor law contains several important exceptions. Agricultural work is exempt from age and hour restrictions for minors, though federal FLSA rules still apply to agricultural employers covered by the FLSA. Minors may work in family businesses wholly owned by their parents or guardians without the standard hour restrictions, though the hazardous occupation prohibitions still apply. Self-employed minors, such as those working in freelance or gig roles, may not fall under traditional employment restrictions, though this remains an unsettled area of law.

Certain occupations have modified hour rules. Minors working in newspaper delivery or distribution may work earlier in the morning. Minors working in agricultural occupations may have different evening work hours. Minors aged 16 and older are subject to fewer restrictions and may work unlimited hours in non-hazardous occupations, though hazardous job prohibitions remain in effect.

Employers are not liable for violations if they relied in good faith on proof of age documentation provided by the minor. If a minor misrepresented their age through falsified documents, the employer may claim a defense against liability. However, employers must exercise reasonable diligence in verifying age. The hazardous occupation restrictions apply regardless of parental consent or the minor's request; employers cannot permit minors to work in prohibited jobs even if parents agree.

Minors aged 16 and 17 may work in most occupations except those designated as hazardous under Missouri law. This provides a substantial expansion of employment opportunities compared to younger teens. No exceptions exist for hazardous occupations; federal and state law prohibit minors under 16 from working in mining, logging, roofing, power-driven machinery operation, and other specifically defined hazardous jobs.

Step 1 — Document Everything: If you are a minor or parent concerned about child labor violations, document all evidence of illegal work practices. Keep written records of: (1) dates and times the minor worked, (2) tasks performed, including whether they are hazardous, (3) wages paid and how they were calculated, (4) any violation of hour limits (e.g., work on school days exceeding 3 hours or total weekly hours exceeding 40), (5) any work performed between 10 p.m. and 5 a.m. without exception, (6) communications with the employer about work schedules or tasks, and (7) photographs or video evidence of hazardous conditions or work. Save text messages, emails, and pay stubs. If the minor is injured, obtain medical records and incident reports.

Step 2 — Internal Complaint Process: Before filing an external complaint, attempt to resolve the issue with the employer if safe to do so. Provide written notice to the employer or supervisor documenting the specific violation (e.g., "My child worked 5 hours on a school day on [date], exceeding the 3-hour limit"). Request corrective action in writing and set a reasonable deadline (typically 10–14 days). Keep a copy of this communication. If the employer fails to correct the violation or retaliates, proceed to Step 3. Internal complaints are not legally required before filing with the state, but they create a clear record and sometimes prompt quick correction.

Step 3 — File with the Appropriate Agency: Missouri child labor violations are investigated by the Missouri Department of Labor and Industrial Relations, Wage and Hour Division. Visit the official website at labor.mo.gov or call (573) 751-3976 to file a complaint. You may also file online through their complaint portal or by mail to: Missouri Department of Labor and Industrial Relations, Wage and Hour Division, 421 East Dunklin Street, Jefferson City, MO 65101. Include in your complaint: (1) the minor's name and date of birth, (2) the employer's business name, address, and contact information, (3) specific violations with dates and times, (4) detailed description of the work performed, (5) copies of documentation (time records, pay stubs, medical records if injured), and (6) your contact information. You may also file a complaint with the U.S. Department of Labor (federal FLSA violations) at the nearest DOL Wage and Hour Division office. There is no filing fee. The deadline to file is generally 2 years from the violation (or 3 years if the violation was willful). Complaints can be filed anonymously, though providing contact information helps investigators follow up.

Step 4 — Investigation Process: After you file, the Missouri Department of Labor will assign an investigator. The investigator will contact you and the employer to gather information. This typically takes 2–4 weeks for initial contact. The investigator will request the employer's employment records, time records, wage records, and documentation of any proof of age provided. The employer will be given an opportunity to respond to allegations. Investigators may conduct workplace inspections to observe work conditions and interview the minor, parents, and coworkers. You should expect to provide detailed testimony about the minor's work history, hours, and tasks. The investigation timeline ranges from 4–12 weeks, depending on complexity and the employer's cooperation. Once the investigation is complete, the Department of Labor will issue findings. If violations are confirmed, the employer may be assessed penalties up to $5,000 per violation. The employer may appeal the findings within 30 days.

Step 5 — When to Consult an Attorney: Consult an employment law attorney if: (1) the violation is serious (e.g., the minor was injured or worked in extremely hazardous conditions), (2) the employer retaliates against the minor or parent (firing, harassment, wage cuts) after the complaint, (3) the Department of Labor's investigation is slow or appears incomplete after 12 weeks, (4) the employer challenges the Department of Labor's findings and you want representation in the appeal, or (5) you believe the minor is entitled to back wages, damages, or other compensation beyond what the Department of Labor may award. An attorney specializing in wage and hour law or employment law can file a private lawsuit under Missouri law or the FLSA for unpaid wages, damages, and attorney's fees. Missouri does not have a specific statute of limitations for child labor civil actions, but the general contract statute of limitations (4 years) may apply.
