Federal rules (FLSA)
Federal law sets the floor: 14 is the minimum age for most non-farm jobs. 14- and 15-year-olds face strict limits — no work during school hours, capped daily and weekly totals, and no late evenings. 16- and 17-year-olds have no federal hour limits but can't perform jobs deemed hazardous. At 18, restrictions end.
Minors in Missouri
Missouri has its own child-labor rules, and where the state and federal rules differ, the stricter one applies. Many states require a work permit (employment certificate) for minors and set their own school-week hour caps. Confirm Missouri's permit requirement and hour limits with the state labor office.
Staying compliant
Keep proof of age and any required work permits on file, and schedule minors within their hour limits — especially the school-week caps. A time clock that flags a minor's hours helps prevent accidental violations.
