Filing a Department of Labor Complaint in Missouri

The Fair Labor Standards Act (FLSA), codified at 29 U.S.C. sections 201–219, establishes the federal baseline for wage and hour protections. The FLSA applies to employers with gross annual sales of at least $500,000 and covers all employees in those organizations, plus certain employees in smaller businesses engaged in interstate commerce. The statute requires employers to pay at least the federal minimum wage (currently $7.25 per hour) and overtime at one and one-half times the regular rate for hours worked over 40 per week. The U.S. Department of Labor Wage and Hour Division (WHD) enforces the FLSA and investigates complaints of wage theft, overtime violations, and misclassification.

Employees can file a wage complaint with the WHD at no cost, and the agency will investigate whether the employer violated the FLSA. If a violation is found, the WHD can recover unpaid wages and liquidated damages (an additional amount equal to the unpaid wages) for affected employees. The statute of limitations for filing a complaint is three years for willful violations and two years for unintentional violations. Additionally, the Occupational Safety and Health Act (OSHA), codified at 29 U.S.C. section 654, allows workers to file confidential complaints about unsafe working conditions with federal OSHA, which has a 30-day filing deadline. Both federal agencies enforce these protections without requiring the employee to hire an attorney first.

Missouri does not maintain a separate state wage and hour enforcement agency with independent statutory protections beyond the federal Fair Labor Standards Act. Instead, Missouri Revised Statutes section 290.500 essentially mirrors federal FLSA requirements, requiring employers to comply with federal minimum wage and overtime standards. This means that Missouri employees are covered by federal law, and state law does not provide additional or enhanced protections for wage and hour claims.

However, Missouri employees can file complaints with the Missouri Department of Labor and Industrial Relations for guidance and referral to the appropriate federal agency. The state department does not independently investigate wage claims but can direct workers to the U.S. Department of Labor Wage and Hour Division. For workplace safety matters, Missouri participates in the federal OSHA program under an agreement with the federal government, meaning OSHA enforces safety standards in Missouri rather than a state agency. This federal enforcement model means that workers in Missouri should file safety complaints directly with federal OSHA, not with a state labor agency.

Missouri law provides no additional wage theft statutes, overtime premium rules, or remedies beyond what federal law offers. The state does not provide for enhanced penalties, attorney fees awards, or extended statutes of limitations for wage claims. Consequently, Missouri is considered a weaker jurisdiction for wage law enforcement because state law does not supplement or strengthen federal FLSA protections. Employees must rely entirely on federal remedies: recovery of unpaid wages, liquidated damages equal to the wage shortfall, and possible attorney fees if they hire counsel and prevail in federal court or before the WHD.

Several important exceptions limit when DOL complaints can be pursued in Missouri. The FLSA contains an administrative exemption that excludes certain executive, administrative, and professional employees from overtime and minimum wage protections if they earn at least $35,568 annually (or the applicable salary threshold under federal regulations) and perform specific job duties. Independent contractors are not covered by the FLSA; only true employees are protected, and Missouri courts apply the common law control test to determine employee status.

Small employers below the $500,000 annual gross sales threshold are not covered by the FLSA unless they are engaged in interstate commerce or in specific industries covered by separate federal statutes. Certain industries are exempt or have modified rules: agricultural workers, domestic workers in private households, and certain transportation workers have limited FLSA coverage. Family business exemptions may apply when the employer is a family corporation or sole proprietorship with only family members employed.

OSHA complaint procedures contain their own exceptions: workers employed by the federal government, certain public sector employees in Missouri, and workers in states with their own OSHA programs not covered by federal OSHA must use different procedures. Additionally, workers cannot recover damages through both a federal FLSA lawsuit and a state common law breach of contract claim for the same wage violation (exclusivity rule). The FLSA statute of limitations begins from the date the employer failed to pay or from the last payment if wages are paid periodically, not from the date the employee discovered the violation.

Step 1: Document the Violation. Keep detailed records of all hours worked, including dates, times, and tasks performed. Save pay stubs, timesheets, emails, and text messages showing wage discussions. Take screenshots of your employer's payroll records if you have access. Write down dates when you raised concerns about unpaid wages or unsafe conditions with management. Record the names and dates of any witnesses to the violation. This documentation is critical because the DOL will review it during the investigation.

Step 2: Attempt Internal Resolution (Optional but Recommended). Send a written email or letter to your employer's human resources or management requesting back pay or correction of the wage violation, with specific details about the underpayment. Keep a copy of this communication. Wait one to two weeks for a response. If the employer refuses or does not respond, you have established that internal remedies have been exhausted and can proceed to file with the DOL. Even if internal resolution succeeds, document the settlement in writing.

Step 3: File the Complaint with the Appropriate Federal Agency. For wage and hour violations (unpaid minimum wage, overtime, wage theft), file with the U.S. Department of Labor Wage and Hour Division. You can file in person, by mail, or online. The Kansas City office is located at 1801 East 18th Street, Kansas City, MO 64108, phone (816) 502-0900. The St. Louis office is at 815 Olive Street, Suite 242, St. Louis, MO 63101, phone (314) 539-6666. For workplace safety violations, file with federal OSHA at 1801 East 18th Street, Kansas City, MO 64108, phone (816) 502-0900, or visit osha.gov. Your complaint must include your name, address, phone number, employer's name and address, description of the violation with specific dates and amounts owed, and the number of employees affected. The deadline is three years from the date of the violation for willful violations, two years for unintentional violations under the FLSA. OSHA complaints must be filed within 30 days of becoming aware of the hazard.

Step 4: Participate in the Investigation. After you file, the WHD will assign an investigator who will contact you to gather details about the alleged violation. The investigator will request access to your employer's payroll records, timesheets, and business records. You may be interviewed by phone or in person. The employer will be notified of the complaint and given an opportunity to respond. The investigation typically takes 60 to 120 days, though complex cases may take longer. The WHD will calculate back wages owed and may recover liquidated damages (double the unpaid wages). You will be notified of the investigation results. If the WHD finds a violation, it will attempt to resolve it through negotiation with your employer; if the employer refuses, the case may be referred to the U.S. Department of Justice for federal court litigation.

Step 5: Consult an Attorney if Necessary. If the WHD investigation does not resolve the matter or if you wish to pursue a private lawsuit, contact an employment law attorney licensed in Missouri who specializes in wage and hour disputes. Many attorneys work on a contingency fee basis (they take payment only if you recover wages). An attorney can file a collective action (class action) on behalf of similarly situated employees, which may increase damages. If you win in federal court, the employer may be ordered to pay your attorney fees and court costs. Do not delay in contacting an attorney; the statute of limitations expires after three years from the violation date.
