Salary Transparency Laws in Missouri: What Employers Must Disclose

Federal law does not mandate salary transparency for private-sector employers in most circumstances. However, the National Labor Relations Act (29 U.S.C. § 157) explicitly protects employees' right to discuss wages, hours, and other terms and conditions of employment with coworkers, regardless of employer policy.

Federal contractors and subcontractors must comply with Executive Order 11246, which requires them to maintain records of wages, hours, and other employment terms. The Equal Employment Opportunity Commission (EEOC) requires covered employers with 100+ employees to submit EEO-1 reports containing aggregate pay data by race, ethnicity, and gender, though individual salary information is not public.

The Fair Labor Standards Act (29 U.S.C. § 201 et seq.) requires employers to maintain wage and hour records but does not require disclosure to employees or applicants. The Paycheck Fairness Act, proposed in Congress multiple times, would expand pay transparency requirements, but has not yet become federal law. The SEC requires publicly traded companies to disclose CEO-to-median-employee pay ratios in certain filings, but this does not extend to private companies.

Missouri has not enacted a comprehensive state salary transparency law. The state does not require private employers to disclose salary ranges to job applicants, current employees, or the public. Missouri's at-will employment doctrine (codified in common law and supported by Missouri Revised Statutes § 375.012 regarding public policy exceptions) does not include salary transparency as a protected issue.

Missouri differs significantly from states like California, Colorado, New York, and Illinois, which have implemented salary transparency laws effective between 2021 and 2024. These states generally require employers to provide salary ranges in job postings or upon request. Missouri has taken no comparable legislative action.

However, Missouri employees retain protections under the National Labor Relations Act § 7, which guarantees the right to discuss wages with coworkers. This federal protection supersedes any employer policy prohibiting wage discussion. Additionally, federal contractors operating in Missouri must comply with Executive Order 11246, which imposes record-keeping and reporting requirements.

Missouri's Department of Labor and Industrial Relations does not administer a salary transparency program. The state relies on federal agencies (EEOC, Department of Labor, Office of Federal Contract Compliance Programs) for enforcement of applicable pay-related requirements. No state agency currently investigates or enforces salary disclosure violations specific to Missouri private-sector employers.

Missouri employers are not subject to salary transparency requirements under state law, so no statutory exceptions apply. However, several important federal exceptions and defenses exist:

Federal contractors under Executive Order 11246 must maintain wage records and cannot discriminate based on protected characteristics in compensation, but are not required to publicly disclose ranges. Collective bargaining agreements may supersede individual transparency obligations, as union contracts typically specify wage scales and grievance procedures. Confidentiality agreements that restrict discussion of wages between coworkers are unenforceable under the National Labor Relations Act, even if signed by the employee.

Employers can maintain legitimate business justifications for pay decisions, such as market rate studies, experience level, and job performance, without disclosing methodology or ranges. At-will employment in Missouri means employers can set any wage within compliance with minimum wage and overtime laws, without transparency obligations.

Small employers with fewer than 50 employees are not subject to Executive Order 11246 or EEO-1 reporting. Exempt employees and independent contractors are treated differently under federal law and may not have access to the same wage discussions protections. Sales positions and commissioned employees may have different pay structures that employers argue justify non-disclosure.

Public-sector employers (state and local government) may have different transparency obligations under state open records laws and union contracts, but these do not apply to private Missouri employers.

Since Missouri has no state salary transparency law, there is no violation mechanism specific to state statute. However, if an employer violates your federal right to discuss wages or is a federal contractor in violation of Executive Order 11246, follow these steps:

Step 1: Document Everything. Write down dates, times, and details of any employer policy prohibiting wage discussion. Keep copies of any job posting that should have included a salary range if you applied to a federal contractor position. Retain paystubs, emails about compensation, and written policies. Photograph or screenshot any employee handbook policies restricting wage conversation. Record the names and dates of conversations with coworkers about pay if applicable. Save any retaliation evidence if you were disciplined after discussing wages.

Step 2: Review Employer Policy and Internal Process. Check your employee handbook or written policies for any wage confidentiality clauses or restrictions on discussing compensation. Document any statement that contradicts this protection. Contact your HR department in writing to request clarification of the policy, keeping a copy for your records. If your employer is a federal contractor, request information about Executive Order 11246 compliance. Determine whether your employer has a union or collective bargaining agreement that addresses pay transparency. Look for any internal grievance process specific to compensation disputes and follow those procedures if available.

Step 3: File a Charge or Report with the Appropriate Federal Agency. If your employer violated your right to discuss wages, file an unfair labor practice charge with the National Labor Relations Board (NLRB) within 180 days. Visit www.nlrb.gov, complete Form 501 (Charge Against Employer), and submit it to the NLRB Regional Office serving Missouri (St. Louis Regional Office: 314-539-7770). Include your name, address, employer details, dates of violation, and specific policy or action that violated your rights.

If your employer is a federal contractor in violation of Executive Order 11246, file a complaint with the Office of Federal Contract Compliance Programs (OFCCP) at www.dol.gov/ofccp. Call 1-866-4-USDOL (1-866-487-3652) or contact the regional office. Include the contractor's name, contract details, nature of the violation, and supporting documentation. The deadline for OFCCP complaints is typically within one year, though this varies by situation.

Step 4: Expect the Investigation Process. The NLRB investigation takes 4-6 weeks on average. An investigator will contact you and the employer separately, requesting written statements and documentation. The NLRB will determine whether there is reasonable cause to believe the employer violated § 7 rights. If reasonable cause is found, the NLRB attempts settlement. If settlement fails, the case may proceed to a hearing before an Administrative Law Judge, which can take 6-12 months. The OFCCP investigation process is similar, with investigators reviewing payroll records, hiring practices, and compensation systems. OFCCP investigations can take 3-6 months or longer depending on complexity.

Step 5: Consult an Employment Attorney. Contact an employment lawyer licensed in Missouri if retaliation occurs after you discuss wages or file a complaint. An employment attorney specializing in labor law can advise on whether your situation involves unfair labor practices, retaliation claims under federal law (29 U.S.C. § 215(a)(3)), or wage and hour violations. Many employment attorneys offer free initial consultations. You may be entitled to back pay, liquidated damages, reinstatement, and attorney's fees if you win. If you work for a federal contractor, an attorney can help determine if Executive Order 11246 applies and advise on remedies.
