Missouri break laws: no state requirement for adults, none outside entertainment, and the federal rules that apply

The short answer

Missouri has no state law requiring meal or rest breaks for adult employees in the private sector. What applies is the federal Fair Labor Standards Act, which does not require breaks either but decides how the ones you give are paid:

• Short breaks of 5 to 20 minutes are paid working time and count toward the 40 hours that trigger overtime (29 CFR 785.18).
• Meal periods of 30 minutes or more can be unpaid, but only if the employee is completely relieved of duty. Eating at the register is working (29 CFR 785.19).
• Nursing mothers get reasonable break time and a private, non-bathroom space to express milk for one year after the child's birth, under the federal PUMP Act.

Minors are the exception. Missouri has no break requirement for minors in ordinary jobs either. The one exception is the entertainment industry, where a youth may not work more than 5.5 hours without a meal break and gets a paid 15-minute rest after every 2 hours of continuous work. Under-16s in other jobs have hours limits: 3 hours on a school day, 8 on a non-school day, 40 in a non-school week, not after 7pm on a school night.

So a Missouri employer can schedule an adult for an 8-hour shift with no break and be within the law. Almost nobody does, because the shift falls apart around hour six, and because once a break policy exists, payroll has to apply it exactly.

What "no law" changes in practice

Your policy is the rule. If the handbook says "30-minute unpaid meal on shifts over 6 hours", that is what payroll must apply, every time. The most common break claim in a state with no break law is a deducted meal period that was never taken.

The deduction test is federal and strict. An unpaid meal period is unpaid only if the person was relieved of all duties. A cashier who covers the floor while eating, a cook who answers the ticket printer, a receptionist who stays at the desk: those 30 minutes are paid, whatever the schedule says. If people routinely work through lunch, pay it or change the schedule.

Short breaks stay on the clock. A 10-minute break is paid and cannot be deducted. Asking staff to clock out for a smoke break is a federal violation, not a Missouri one.

Minors need the break written into the shift. None outside entertainment: put it on the schedule with a start time, and make sure the person actually takes it.

Wages, overtime and the other Missouri rules that do bite

Minimum wage and overtime. $15.00 an hour since January 1, 2026 under Proposition A, indexed from 2027. Overtime at time and a half after 40 hours in the workweek. There is no daily overtime in Missouri; a 12-hour shift in a 36-hour week is straight time.

Work certificates. Under-16s need one issued by the school district; keep it with the schedule records.

Retail on Sundays. No state restriction; the schedule is a policy matter. St. Louis and Kansas City have no local break ordinances either.

Building it into the schedule

1. Write a 30-minute unpaid meal period into every shift over 6 hours, with a start time. It is what most employers in Missouri do, and it keeps the deduction defensible.
2. Give a paid 10-minute break per 4 hours, on the clock. A sixth of an hour, and fewer errors in the afternoon.
3. Make people clock out and in for the unpaid meal. It is the only proof the 30 minutes were taken and that payroll was right to deduct them.
4. Flag minors on the roster so their break rule and hours limits are applied without anyone having to remember.
5. Publish the schedule two weeks ahead. No law requires it in Missouri; turnover does.

Squadra writes the break inside each shift, records unpaid meal periods as a clock-out and clock-in, marks minors so their rules apply, and shows the week's hours per person so the 40-hour line is visible before it is crossed. Free up to 10 employees: see the pricing.

Around Missouri: Kentucky requires a lunch window and paid rest breaks; Tennessee 30 minutes at 6 hours; Illinois 20 minutes at 7.5 hours; Kansas, Iowa, Arkansas, Oklahoma and Nebraska have no adult rule (Nebraska requires 30 minutes in assembly plants and workshops).
