Overtime Pay Rules in Missouri: Who Qualifies & What You Earn

The Fair Labor Standards Act (FLSA), 29 U.S.C. § 207, establishes the federal minimum overtime requirement in the United States. Under the FLSA, covered employees must receive overtime compensation of at least 1.5 times their regular hourly rate for all hours worked over 40 in a seven-day workweek. The FLSA applies to private employers with annual gross sales of $500,000 or more, as well as hospitals, schools, nursing homes, and government agencies without a sales threshold.

The FLSA covers both hourly and salaried employees, though salaried employees must meet specific duty tests to qualify as exempt from overtime. The law does not require daily overtime or premium pay for weekend or holiday work unless hours exceed 40 for the week. The U.S. Department of Labor Wage and Hour Division (WHD) enforces the FLSA. Remedies for overtime violations include unpaid overtime wages, an equal amount in liquidated damages, attorney fees, and costs under 29 U.S.C. § 216.

Employees have three years to file a lawsuit for overtime violations under 29 U.S.C. § 255. The FLSA also permits collective actions where multiple employees alleging the same violation can sue together. Employers cannot waive FLSA rights, and any agreement to work without overtime pay is void.

Missouri does not have a state-specific overtime law that differs from or enhances the federal Fair Labor Standards Act. Mo. Rev. Stat. § 290.502 establishes Missouri's minimum wage but does not create separate overtime requirements. This means overtime protections in Missouri are entirely dependent on federal law under the FLSA.

Unlike some states (such as California) that require daily overtime or provide overtime protections to a broader class of employees, Missouri defers to the FLSA's 40-hour-per-week overtime standard. Employers in Missouri must comply only with federal FLSA requirements; there is no state overtime law that creates additional obligations. This means employees in Missouri do not benefit from accelerated overtime thresholds, daily overtime rules, or state-level enforcement mechanisms separate from federal oversight.

Missouri is an at-will employment state, meaning employment relationships are presumed to be at-will absent a written contract. However, at-will status does not eliminate overtime obligations; employers must still pay overtime wages required by the FLSA. Missouri has not enacted any state-level wage-and-hour statute that exceeds FLSA coverage or creates categories of protected workers with special overtime rights.

Federal enforcement through the U.S. Department of Labor Wage and Hour Division remains the primary mechanism for overtime enforcement in Missouri. Employees may also pursue overtime claims through private lawsuits in federal court or, in some cases, state court. Missouri does not provide state-administered overtime complaint procedures or state-level remedies beyond those available under the FLSA.

Certain categories of employees are exempt from FLSA overtime requirements entirely, and Missouri recognizes these federal exemptions without modification. The primary exemptions are the executive, administrative, and professional (EAP) exemptions. An employee qualifies as exempt from overtime only if they earn at least the federal salary threshold (currently $35,568 per year as of 2024) and perform duties that are primarily executive, administrative, or professional in nature.

For executive employees, the exemption requires that the employee have responsibility for supervising two or more full-time employees and have authority to hire, fire, or make recommendations on hiring and firing decisions. Administrative employees must perform office or non-manual work directly related to business operations or management and have discretionary authority to make decisions. Professional employees must perform work requiring advanced knowledge in a field of science or learning, or artistic creativity, acquired through specialized education.

Sales employees who work in a retail establishment can be exempt from overtime if they are paid on a commission basis and their regular rate of pay is at least 1.5 times the federal minimum wage. Highly compensated employees earning $107,432 or more per year (as of 2024) may qualify for exemption if they perform one primary duty that would otherwise qualify them for exemption.

Other FLSA exemptions include outside sales employees, certain agricultural workers, and employees of certain small newspapers. Employees must meet all criteria for an exemption; partial qualification does not result in exemption status. Employers have the burden of proving by clear and convincing evidence that an employee qualifies for exemption. Misclassifying an employee as exempt when they do not meet all criteria constitutes an overtime violation and exposes the employer to liability for back wages, liquidated damages, attorney fees, and costs.

Step 1: Document Everything. Keep detailed records of all hours worked each day, including start times, end times, breaks, and total daily hours. Save all timesheets, email communications, text messages, calendar entries, or any other evidence showing hours worked. If your employer does not provide timesheets, create your own handwritten record with dates, times, and witness signatures if possible. Photograph or screenshot digital timekeeping records. Save copies of pay stubs to track which weeks appear to include overtime hours but lack overtime pay.

Step 2: Attempt Internal Resolution (Optional but Recommended). Request a written meeting with your manager or HR department to explain the overtime issue. Submit a written complaint via email stating the specific dates and hours you believe were unpaid overtime, and request a written response with an explanation. Keep copies of all internal communications. Request that HR calculate whether you were properly compensated for overtime hours and ask for written confirmation of their analysis. While not legally required, this creates a paper trail and may prompt corrective action without litigation.

Step 3: File a Complaint with the U.S. Department of Labor Wage and Hour Division. Visit the WHD website at www.dol.gov/agencies/whd or call 1-866-4-USWAGE (1-866-487-9243) to locate your regional office. You can file a complaint by phone, mail, or in person at no cost. Provide your name, address, phone number, and email; your employer's name, address, and phone number; a detailed description of the overtime work performed; the dates and hours worked; and your regular hourly rate. The WHD will investigate at no cost to you and may pursue the employer directly for unpaid wages. There is no filing deadline to file a complaint with the WHD, but the statute of limitations for back wages is three years.

Step 4: Understand the Investigation Process. After you file a complaint, the WHD will contact your employer and may request payroll records, timesheets, and business records. You may be interviewed by a WHD investigator. The WHD will determine whether your employer violated the FLSA and calculate the amount of unpaid overtime owed. This process typically takes 30–90 days but can take longer depending on case complexity and WHD workload. The WHD will notify you and your employer of the findings. If the employer owes wages, the WHD will attempt to collect voluntarily; if unsuccessful, the Department of Labor may pursue court action on your behalf or you may pursue a private lawsuit.

Step 5: Consider Filing a Private Lawsuit or Collective Action. If the WHD investigation does not result in resolution, consult an employment attorney in Missouri who specializes in wage-and-hour law. Many attorneys work on a contingency basis for overtime cases, meaning you pay no upfront fees. Your attorney can file a lawsuit in federal district court or, in some cases, state court in Missouri. Under the FLSA, you may file a collective action allowing multiple employees with similar claims to sue together, which increases leverage and reduces individual costs. You are entitled to recover unpaid overtime wages, an equal amount in liquidated damages (essentially doubling the recovery), attorney fees, and court costs. Speak with an attorney within one year of the violation to preserve your claim, and certainly before the three-year statute of limitations expires.
