Filing a State Labor Board Complaint in Massachusetts

Last reviewed: September 2026

Quick Answer

You can file a labor board complaint in Massachusetts by contacting the state Department of Labor's Wage and Hour Division (online at mass.gov/lwd or by phone at 617-626-6975) or the federal National Labor Relations Board (NLRB) for union-related issues. Most wage and hour complaints must be filed within three years of the violation, while NLRB complaints must be filed within 180 days of the unfair labor practice. Massachusetts law protects you from retaliation for filing a complaint under Massachusetts General Laws Chapter 149, Section 24L.

Key Facts

  • Massachusetts employees can file complaints with the state Department of Labor or federal NLRB for wage theft, unsafe conditions, or unfair labor practices.
  • File wage complaints within 3 years of the violation; file NLRB complaints within 180 days of the unfair labor practice.
  • The Massachusetts Department of Labor investigates wage, hour, and workplace safety violations without requiring an attorney.
  • Retaliation against employees for filing labor board complaints is illegal under Massachusetts law and federal law.
  • Many complaints can be filed online or by phone; investigation is typically free and confidential.

Federal Law: The Baseline

Federal law provides multiple avenues for labor board complaints. The Fair Labor Standards Act (FLSA), 29 U.S.C. § 201 et seq., allows employees to file wage and hour complaints with the U.S. Department of Labor's Wage and Hour Division for unpaid minimum wage, overtime, or misclassified independent contractors. The National Labor Relations Act (NLRA), 29 U.S.C. § 151 et seq., allows employees to file unfair labor practice charges with the National Labor Relations Board (NLRB) within 180 days of the violation for issues including improper discipline, discrimination, retaliation, or interference with union organizing rights.

Occupational Safety and Health Act (OSHA), 29 U.S.C. § 660, allows employees to report workplace safety hazards to the federal OSHA office; however, most states including Massachusetts operate an OSHA-approved state plan. Title VII of the Civil Rights Act of 1964, 42 U.S.C. § 2000e, allows discrimination complaints with the Equal Employment Opportunity Commission (EEOC) within 180 or 300 days depending on state deferral status.

Federal law covers employers with 4 or more employees (FLSA), 1 or more employees (NLRA), and any employer with 1 or more employee (Title VII and OSHA). The EEOC and Wage and Hour Division investigate complaints at no cost to the employee. Remedies include back pay, liquidated damages, civil penalties, reinstatement, and compensatory damages.

Massachusetts Law: What's Different

Massachusetts General Laws Chapter 149 establishes a comprehensive state labor enforcement regime that in many respects exceeds federal protections. The Massachusetts Department of Labor's Wage and Hour Division (citation: M.G.L. c. 149, §§ 150–180) enforces wage, hour, and minimum wage violations. Massachusetts minimum wage is currently higher than the federal minimum wage and is adjusted annually; this is enforced under M.G.L. c. 149, § 150. The state covers all employees, including agricultural workers and domestic workers, who are typically excluded from federal FLSA coverage.

Massachusetts General Laws Chapter 149, Section 24L provides paid sick leave rights (5 days per year for employers with 6+ employees) and explicitly prohibits retaliation for requesting or using paid sick leave or for filing related complaints. This protection is broader than the federal FLSA, which does not mandate paid sick leave. Section 24K similarly prohibits retaliation for complaints about wage violations, creating an independent state cause of action stronger than the implied protection under federal law.

Employers covered under Massachusetts state law include all employers with 1 or more employee, broader than many federal statutes. The statute of limitations for wage claims is three years under M.G.L. c. 149, § 150, compared to the federal two-year or three-year FLSA period. Remedies under Massachusetts law include unpaid wages with interest, liquidated damages equal to the unpaid wages (not merely equal to the violation, as under federal law), and reasonable attorney's fees and costs. M.G.L. c. 149, § 24L and § 24K create private rights of action, allowing employees to sue directly in court without exhausting administrative remedies, unlike federal NLRA claims which require NLRB adjudication.

Massachusetts recognizes a broader "wage" definition than federal law, explicitly including commissions, bonuses, and certain benefits. The state also applies stricter independent contractor classification rules than the federal ABC test, incorporating the ABC test from the state Misclassification of Employees Law, M.G.L. c. 149, § 148B.

Key Numbers & Thresholds

Massachusetts wage complaints: file within 3 years of the violation (compared to 2 years under federal FLSA or 3 years if employer's violation was willful). NLRB unfair labor practice charges: file within 180 days of the violation. Paid sick leave complaints: file within 3 years under M.G.L. c. 149, § 24K. Massachusetts minimum wage: $14.25 per hour as of 2024 (indexed annually). Tipped minimum wage: $6.15 per hour (but tips must bring total to at least minimum wage). Employers covered by state wage and hour law: 1 or more employee. Employers covered by paid sick leave law: 6 or more employees. Private right of action available: yes, for wage and retaliation claims under M.G.L. c. 149.

Exceptions & Special Cases

Massachusetts labor law contains important exceptions and limits on complainant protections. Section 24L retaliation protection applies to employees who in good faith report violations of wage and hour law; if the employee's complaint is proven false and malicious, the protection may not apply, though Massachusetts courts construe this narrowly. Independent contractors are generally excluded from wage and hour protections under M.G.L. c. 149, though Massachusetts applies a strict ABC test for classification that presumes employee status unless all three prongs are met.

Employees covered by collective bargaining agreements may have different complaint procedures under the CBA; some courts require exhaustion of union grievance procedures before filing state complaints, though this is not required as an absolute matter. Domestic workers employed in private homes were historically excluded from certain wage protections but have been incrementally included; however, live-in domestic workers may have different hour-counting rules.

Public sector employees (state and municipal workers) are subject to different procedural rules; many must file complaints through civil service procedures or the Department of Labor Relations rather than the Wage and Hour Division, though the substantive wage law applies. Some federal employees working in Massachusetts may be covered by federal civil service law rather than state law, though federal contractor protections under the Davis-Bacon Act and Service Contract Act do apply to federal contractors.

Retaliation protection under Section 24L does not protect employees who report violations outside the scope of wage and hour law; discrimination or safety complaints may require separate EEOC or OSHA filings. Complaints about alleged criminal conduct (as distinguished from civil wage violations) may require police reporting rather than labor board complaint filing. Statute of limitations defenses will apply; complaints filed outside the 3-year window are barred unless the violation was willful.

What to Do If Your Rights Are Violated

**Step 1: Document the Violation.** Keep detailed records of all hours worked (start and end times, breaks taken), wage statements (pay stubs), and any written communications about wages, classification, or complaints. Photograph or scan pay stubs and emails. Create a written log with dates, times, and what occurred (e.g., "July 15, 2024: worked 10 hours, paid only for 8 hours; shift ended 6 PM, clock-out recorded 4 PM"). Note the names of any witnesses or co-workers who can verify the violation. Save all records electronically and in multiple locations. This documentation is critical because the burden of proof falls on the employer to show wages were paid.

**Step 2: Internal Complaint Process (Optional but Recommended).** Send a written complaint to your employer's human resources department or payroll manager, ideally by email so you have a record. State the specific violation: "I was not paid for 15 hours worked during the week of July 8–14" or "I was denied paid sick leave when I requested it on July 20." Request a written response within 5 business days. Do not expect this to resolve the matter, but it creates an administrative record and demonstrates good faith. Keep copies of the email and any response. Under M.G.L. c. 149, § 24L, retaliation after this complaint is prohibited; if you are disciplined or terminated after filing an internal complaint, document this immediately.

**Step 3: File a Complaint with the Massachusetts Department of Labor or NLRB.** For wage and hour violations, file with the Massachusetts Department of Labor's Wage and Hour Division: Online at mass.gov/lwd (select "File a Complaint"), by phone at 617-626-6975, or by mail to 19 Staniford Street, Boston, MA 02114. You will need to provide: your name, address, and phone number; employer's name, address, and phone number; description of the violation with specific dates and amounts; and your documentation (pay stubs, emails, work logs). The complaint is free and can be filed confidentially (the employer may not know your name initially). For union-related unfair labor practices, file a charge with the National Labor Relations Board Boston Regional Office at 15 New England Executive Park, Burlington, MA 01803, or online at nlrb.gov. The 180-day filing deadline for NLRB charges is strictly enforced.

**Step 4: Investigation and Resolution.** The Massachusetts Department of Labor will assign an investigator who will contact you and the employer. The investigation typically takes 30–60 days but may extend longer if the case is complex. The investigator will request payroll records, time sheets, and other documentation from the employer and may conduct interviews. You have the right to participate in the investigation; provide any additional evidence promptly. If the investigation confirms a violation, the department will attempt to reach a settlement or may issue a citation and civil penalty to the employer. You will be notified of the outcome. If the employer refuses to comply, the department can refer the case for further legal action or to the Attorney General's office. For NLRB charges, an investigator will interview both parties; if merit is found, the NLRB General Counsel may issue a complaint and the case proceeds to a hearing before an administrative law judge.

**Step 5: When to Consult an Attorney.** Contact an employment attorney if: (1) the investigation does not resolve the matter within 90 days, (2) the employer retaliated against you for filing the complaint, (3) the amount owed is substantial (over $5,000), or (4) the case involves multiple violations or complex issues. Many Massachusetts employment attorneys work on contingency (no upfront fee). Under M.G.L. c. 149, § 150, an employee who prevails in wage litigation can recover attorney's fees and costs, so a contingency arrangement is often possible. An attorney can file a civil lawsuit in Superior Court if administrative resolution fails and the statute of limitations has not expired.

Frequently Asked Questions

Can I file an anonymous complaint with the Massachusetts Department of Labor?

Yes, you can file an anonymous complaint, though the Department of Labor may need to contact you for additional information during the investigation. When filing online or by phone, you can request that your identity not be disclosed to the employer during the initial stages of the investigation. However, if the case proceeds to formal enforcement or litigation, your identity may need to be revealed as part of the legal process. In practice, most investigations do become known to the employer, so expect that possibility. Filing under your name typically results in a faster investigation because the investigator can directly contact you with questions. If you are concerned about retaliation, report this concern when filing—Massachusetts law prohibits retaliation under M.G.L. c. 149, § 24L, and your complaint will be documented as a protected activity.

How long does it take for the Massachusetts Department of Labor to investigate my complaint?

A typical investigation takes 30 to 60 days from the date you file, though this can vary depending on case complexity and the agency's workload. If the employer is uncooperative or there are multiple locations or pay periods involved, the investigation may take up to 90 days or longer. You will receive updates from your assigned investigator; contact the department if you have not heard back within 60 days. The department is not required to provide a specific investigation timeline, so timely follow-up from you can help accelerate the process. If your case involves fraud or criminal conduct, the agency may coordinate with law enforcement, which can extend the timeline. Once the investigation concludes, the department will notify you in writing of the outcome and whether the employer violated the law.

What happens if my employer retaliates against me after I file a labor board complaint?

Retaliation is illegal under Massachusetts General Laws Chapter 149, Section 24L. Retaliation includes termination, suspension, demotion, pay reduction, loss of benefits, schedule changes, or any other adverse action taken because you filed a complaint or reported a wage violation. If you experience retaliation, document it immediately with dates, times, and details. File a separate retaliation complaint with the Massachusetts Department of Labor within 3 years of the retaliatory action. You can also file a civil lawsuit for retaliation under M.G.L. c. 149, § 24L, seeking damages and attorney's fees. The law prohibits retaliation even if your original wage complaint is later found to be without merit, as long as you filed it in good faith. Retaliation complaints are taken seriously and can result in significant penalties against the employer, including additional damages.

If I am an independent contractor, can I file a wage complaint with the Massachusetts Department of Labor?

Independent contractors are generally not covered by Massachusetts wage and hour law. However, Massachusetts applies a strict classification test (the ABC test) under M.G.L. c. 149, § 148B. Under this test, a worker is presumed to be an employee unless the employer proves all three criteria: (A) the worker is free from control and direction, (B) the worker performs work outside the usual course of the employer's business, and (C) the worker is customarily engaged in an independently established trade. Many employers misclassify workers as independent contractors when they should be employees. If you believe you are misclassified, file a wage complaint with the Department of Labor and explain your relationship with the employer. The investigator will evaluate whether the classification meets the ABC test. If misclassified, you are entitled to back wages for all work performed, unpaid overtime, and other benefits.

Can I file a complaint if I am undocumented or working without authorization?

Yes, all workers in Massachusetts, regardless of immigration status, have the right to file wage and hour complaints and are protected by wage laws under M.G.L. c. 149. The Massachusetts Department of Labor does not inquire about immigration status, and you cannot be denied protection because you are undocumented. Filing a wage complaint will not trigger immigration enforcement; the labor complaint goes to the state Department of Labor, not to federal immigration authorities (ICE). However, if your employer reports you to ICE in retaliation for filing a complaint, this is itself retaliation and is illegal. Document any retaliatory threats. Many employment attorneys in Massachusetts specialize in protecting undocumented workers' rights and can advise you confidentially. You have the same right to minimum wage, overtime pay, and paid sick leave as any other employee, regardless of work authorization status.
