Filing a Department of Labor Complaint in Massachusetts

Last reviewed: September 2026

Quick Answer

In Massachusetts, you file DOL complaints with three different agencies depending on the violation: the Massachusetts Department of Labor for wage theft (deadline 3 years), the Occupational Safety and Health Administration (OSHA) for workplace safety violations, and the Massachusetts Commission Against Discrimination (MCAD) for discrimination or harassment based on protected class status (300-day deadline). All complaints can be filed online, by phone, or in person, and retaliation for filing is illegal under state and federal law.

Key Facts

  • Massachusetts workers can file DOL complaints for wage violations, safety hazards, and discrimination through state and federal agencies.
  • Wage complaints must be filed within 3 years under Massachusetts law; OSHA complaints have no strict deadline.
  • File wage complaints with Massachusetts Department of Labor; safety complaints with OSHA; discrimination with MCAD.
  • The state processes most complaints within 30-60 days; investigations typically take 2-6 months.
  • Retaliation for filing a DOL complaint is illegal under Massachusetts law.

Federal Law: The Baseline

Federal wage and hour law under the Fair Labor Standards Act (FLSA), 29 U.S.C. § 201 et seq., covers most Massachusetts employers and requires payment of minimum wage and overtime compensation. The U.S. Department of Labor's Wage and Hour Division investigates FLSA violations, including unpaid wages, misclassification, and overtime disputes. The federal statute of limitations for FLSA claims is 2 years (3 years for willful violations). The FLSA prohibits retaliation under 29 U.S.C. § 215(a)(3), and workers can also file private lawsuits for unpaid wages plus an equal amount in liquidated damages.

For workplace safety, the federal Occupational Safety and Health Act (OSH Act), 29 U.S.C. § 651 et seq., applies nationwide through OSHA. Federal OSHA requires employers with 11+ employees to comply with safety standards and prohibits retaliation under 29 CFR § 1977.8 for reporting hazards. Workers can file OSHA complaints by phone, online, or in person at any OSHA office with no filing deadline or fee.

For discrimination, Title VII of the Civil Rights Act of 1964, 42 U.S.C. § 2000e et seq., prohibits discrimination based on race, color, religion, sex, or national origin in employers with 15+ employees. The Equal Employment Opportunity Commission (EEOC) investigates Title VII charges filed within 180 days of the violation (or 300 days in deferral states). The EEOC can award back pay, front pay, compensatory damages, and attorney's fees.

Massachusetts Law: What's Different

Massachusetts provides stronger protections than federal law in several key areas. Under Massachusetts General Laws chapter 149, section 150, employers must pay all wages due on a regular schedule, and employees can recover unpaid wages plus penalties and attorney's fees. The Massachusetts statute of limitations for wage claims is 3 years—longer than the federal 2-year FLSA period. Massachusetts also covers more employers than the FLSA: Massachusetts wage law applies to employers with as few as one employee, whereas the FLSA only covers employers with annual gross revenues of $500,000 or more.

Massachusetts General Laws chapter 149, section 24L explicitly prohibits retaliation against any employee who files a wage complaint, requests a wage statement, or participates in an investigation. This protection applies to all employers regardless of size. A worker who suffers retaliation can sue the employer directly for damages, and the employee does not need to exhaust administrative remedies first.

For discrimination and harassment, Massachusetts General Laws chapter 151B is significantly broader than Title VII. The Massachusetts Commission Against Discrimination (MCAD) enforces state law protections against discrimination based on race, color, religion, national origin, sex, gender identity, sexual orientation, disability, age (40+), military service, genetics, and status as a victim of domestic violence, sexual assault, or stalking. MCAD covers employers with one or more employees—far broader than Title VII's 15-employee threshold. Massachusetts also recognizes a cause of action for "transgender discrimination" explicitly, provides stronger sexual harassment protections, and has a longer filing deadline of 300 days (versus the federal EEOC 180-day deadline in non-deferral states). MCAD can award damages including back pay, front pay, emotional distress, and attorney's fees up to $50,000 for administrative relief (with additional remedies available in court).

For workplace safety, Massachusetts maintains its own state OSHA program (Massachusetts Department of Labor, Division of Occupational Safety and Health—DOSH) approved by federal OSHA. DOSH has authority equal to or greater than federal OSHA and can enforce state regulations that exceed federal standards. Massachusetts workers file safety complaints with DOSH rather than federal OSHA, and retaliation protection is the same as federal law.

Key Numbers & Thresholds

Wage complaints: 3-year statute of limitations under Massachusetts law (versus 2 years federally). MCAD discrimination complaints: 300 days to file (versus 180 days for federal EEOC in most states). OSHA/DOSH safety complaints: no filing deadline. Employer coverage for wage law: 1+ employees in Massachusetts (versus $500,000+ annual revenue federally under FLSA). MCAD coverage: 1+ employees (versus 15+ under Title VII). Massachusetts minimum wage: $15.00 per hour as of January 2024.

Exceptions & Special Cases

Massachusetts wage law does not apply to independent contractors, even if misclassified; however, the employee bears the burden of proving independent contractor status, not the employer. Salaried employees in bona fide executive, administrative, or professional roles are exempt from minimum wage and overtime requirements under Massachusetts regulations similar to federal law, but the burden of proof is on the employer to establish the exemption clearly.

Wage complaints may be barred if the employee signed a valid non-waiver agreement or settlement, but employees cannot be required to waive the right to file a complaint as a condition of employment. Employees who are already receiving unemployment benefits cannot simultaneously recover backpay for the same period without potential overpayment issues, though they can file a wage complaint.

MCAD discrimination complaints cannot proceed if the conduct was already resolved in a prior MCAD proceeding between the same parties, or if a union grievance arbitration award conclusively addresses the same facts (though the arbitration must provide adequate review and remedies comparable to MCAD). Complaints alleging only breach of contract (not discrimination) fall outside MCAD's jurisdiction and must be pursued in civil court.

Retaliation protections do not extend to employees who file false complaints knowing they are false, or to complaints that are purely frivolous and filed in bad faith. However, a complaint that turns out to be incorrect in fact does not lose protection if the employee had reasonable grounds to believe it was true when filed.

OSHA/DOSH complaints can proceed only if the alleged hazard violates a specific OSHA or Massachusetts DOSH safety standard; general workplace inconvenience or employee preference for different working conditions does not qualify. Workers cannot file retaliation complaints under OSHA more than 30 days after the retaliatory act unless they are part of an ongoing pattern of retaliation.

What to Do If Your Rights Are Violated

Step 1: Document Everything. Keep a written record of the violation as soon as it occurs. For wage violations, save all pay stubs, timesheets, email communications about hours worked, text messages from your manager about work, and any written wage agreements or offer letters. For safety violations, take photographs or video of the hazard if safe to do so, note the date and time of the violation, and identify any coworkers who witnessed it. For discrimination or harassment, write down the date, time, location, what was said or done, who was involved, and any witnesses. Save all documents in a secure location (personal email, cloud storage, or physical copies at home) that the employer cannot delete.

Step 2: File an Internal Complaint (if safe to do so). Before filing with a government agency, send a written complaint to your manager, HR department, or company compliance hotline describing the violation, the date it occurred, and what remedy you are seeking. Use email so you have a timestamped record. Keep a copy for yourself. Internal complaints are not required by law, but they can demonstrate that the employer had notice of the problem and may strengthen your case. If you reasonably fear retaliation from reporting internally, you can skip this step and go directly to the agency complaint.

Step 3: File with the Appropriate Agency. For wage violations (unpaid overtime, incorrect minimum wage, off-the-clock work, misclassification), file a wage complaint with the Massachusetts Department of Labor, Office of the Attorney General, or the U.S. Department of Labor Wage and Hour Division. You can file online at mass.gov/dol or by calling (617) 626-5400 to request a complaint form. Provide your name, address, phone number, employer name and address, description of the violation, dates it occurred, and your preferred remedy (unpaid wages, penalties, or attorney's fees reimbursement). The deadline is 3 years from the violation.

For workplace safety violations (unsafe equipment, lack of protective gear, chemical hazards, unsanitary conditions), file a complaint with the Massachusetts Department of Labor, Division of Occupational Safety and Health (DOSH). File online at mass.gov/dol or call (617) 969-7177 toll-free at 1-800-SOS-OSHA (1-800-767-6742). You can file anonymously. Provide a clear description of the hazard, the location, when you first became aware of it, and the number of affected workers. There is no filing deadline. DOSH will investigate within 48 hours for imminent danger situations.

For discrimination, retaliation, harassment, or violation of civil rights (based on race, color, religion, sex, gender identity, sexual orientation, disability, age, military status, domestic violence victim status, or genetic information), file a complaint with the Massachusetts Commission Against Discrimination (MCAD). File online at mcad.mass.gov, by mail at 436 Dwight Street, Springfield, MA 01103 or One Ashburton Place, Room 601, Boston, MA 02108, or by phone at (617) 994-6000 (Boston) or (413) 739-2145 (Springfield). Provide your name, contact information, employer name and address, names of decision-makers involved, description of the discriminatory or retaliatory conduct, dates it occurred, any witnesses, and what remedy you seek (back pay, front pay, emotional distress damages, reinstatement, policy changes). The deadline is 300 days from the most recent act of discrimination or retaliation.

Step 4: Agency Investigation and Timeline. After you file, the agency will send you a confirmation and assign an investigator. For wage complaints, the Massachusetts Attorney General's Office typically begins investigation within 2-4 weeks and contacts your employer to request wage records, timesheets, and payroll documentation. The investigation takes 30-90 days on average. If the agency finds a violation, it will issue a demand for back wages plus penalties (often 50% of unpaid wages). The employer typically has 10 days to comply or face further enforcement.

For DOSH safety complaints, an inspector will visit the workplace within 48 hours for imminent danger, or within 5-7 business days for non-emergency violations. DOSH will interview you and other workers, inspect the hazard, and examine the employer's safety procedures and records. You have the right to speak privately with the inspector and to walk the worksite with the inspector. The inspection report is typically completed within 2-3 weeks. If violations are found, DOSH issues citations with specific corrective deadlines, usually 15-30 days.

For MCAD discrimination complaints, you will be contacted by an investigator within 30 days. MCAD will interview you, gather evidence from both you and the employer, and may conduct a conciliation conference to try to resolve the complaint without a hearing. The investigation typically takes 60-120 days. If the investigator finds probable cause of discrimination, MCAD will schedule a hearing before an administrative law judge within 60-90 days after probable cause.

Step 5: Escalation and Legal Representation. If the agency investigation does not resolve your complaint to your satisfaction, or if the employer does not comply with agency demands within the deadline, consult an employment law attorney. For wage violations, contact an attorney who specializes in wage and hour law; many offer free initial consultations and work on contingency (meaning they take payment only if you win). An attorney can file a private lawsuit in Massachusetts Superior Court under state wage law (Massachusetts General Laws chapter 149) or under the federal FLSA. If you win a wage lawsuit, you can recover unpaid wages, penalties, court costs, and the employer may have to pay your attorney's fees.

For discrimination or harassment cases, consult an employment discrimination attorney. If MCAD issues a "right to sue" letter or if administrative proceedings reach a deadlock, an attorney can file a civil lawsuit in Superior Court or pursue federal claims through the EEOC (which can issue a federal right to sue letter allowing a lawsuit under Title VII). For safety violations, if DOSH citations are not complied with, consult an attorney about filing a complaint with OSHA's regional office or pursuing a private right of action for unsafe conditions.

Frequently Asked Questions

Can I file a DOL complaint anonymously in Massachusetts?

Yes, but the protections differ by complaint type. For OSHA/DOSH safety violations, you can file completely anonymously by phone or online without providing your name, and DOSH will still investigate. However, anonymous complaints may be lower priority than identified complaints because the agency cannot contact you for follow-up information. For wage complaints with the Massachusetts Department of Labor or Attorney General, you can file confidentially, but you must provide identifying information so the agency can contact you during the investigation and you can receive any settlement or back pay awarded. For MCAD discrimination complaints, you must provide your name, contact information, and identifying details about the alleged discrimination, because MCAD needs to identify you as the charging party in formal proceedings. Anonymity in MCAD complaints is not possible because the respondent employer has a right to know who is accusing them and must be given an opportunity to respond.

What happens if my employer retaliates against me after I file a DOL complaint in Massachusetts?

Retaliation is illegal under Massachusetts state law and federal law. Under Massachusetts General Laws chapter 149, section 24L, an employer cannot discharge, discipline, threaten, harass, or discriminate against an employee for filing a wage complaint, requesting wage information, or participating in a DOL investigation. Retaliation includes reduced hours, suspension, negative performance reviews written after the complaint, being assigned worse shifts or tasks, or any adverse employment action motivated by the complaint. If you experience retaliation, you can file a separate retaliation complaint with the same agency or file a private lawsuit in Superior Court. You must file a retaliation complaint within 3 years. Under federal law, 29 U.S.C. section 215(a)(3) (FLSA) and 29 CFR section 1977.8 (OSHA) also prohibit retaliation, giving you multiple avenues for relief. An employer cannot legally terminate you while a DOL investigation is pending, and doing so is strong evidence of retaliation. Many retaliation cases result in reinstatement, back pay, damages for emotional distress, and attorney's fees.

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

Investigation timelines vary significantly based on complaint type and complexity. For wage complaints, the initial investigation typically takes 30-90 days from the date you file. The agency first sends a written notice to your employer requesting wage records, timesheets, and payroll documentation. Most employers respond within 15-30 days. If the records are clear and show a violation, the agency may resolve the case within 60-90 days total. However, if the employer disputes the facts, refuses to cooperate, or the case involves multiple employees or years of unpaid wages, investigation can stretch to 6 months or longer. For DOSH safety complaints, an initial inspection occurs within 48 hours for imminent danger situations, or 5-7 business days for standard complaints. The inspection report is usually completed within 2-3 weeks after the inspector's visit. For MCAD discrimination complaints, the investigation phase takes 60-120 days on average, though complex cases with multiple witnesses or lengthy employment histories may take longer. MCAD is required by law to issue a determination of probable cause or no probable cause within 120 days of filing (with possible extensions).

If I file a wage complaint in Massachusetts, how much back pay can I recover?

Under Massachusetts General Laws chapter 149, section 150, you can recover all unpaid wages due, calculated at your regular rate of pay for all hours worked. The amount is the difference between what you were paid and what you should have been paid under Massachusetts minimum wage law ($15.00 per hour as of 2024) and overtime rules (1.5x regular rate for hours over 40 per week, or as required by your employment contract). In addition to back wages, you are entitled to recovery of penalties equal to triple the unpaid wages (or the maximum penalty of $10,000, whichever is greater) under Massachusetts General Laws chapter 149, section 150. You can also recover attorney's fees and court costs if you pursue a civil lawsuit, and prejudgment interest on the unpaid wages (currently 12% per year in Massachusetts). For example, if you worked 50 hours per week for 52 weeks at $15 per hour minimum wage but were paid only $12 per hour, your unpaid wages would be $156 per week × 52 weeks = $8,112 in back wages, plus triple damages of $24,336 in penalties, plus attorney's fees and interest. However, the employer can reduce the amount owed if you were paid partially but not fully (the penalty applies only to the unpaid portion). The 3-year statute of limitations means you can recover back pay going back 3 years from the date you file, not just recent violations.

Do I need a lawyer to file a DOL complaint in Massachusetts, and what does it cost?

No, you do not need a lawyer to file a complaint with the Massachusetts Department of Labor, DOSH, or MCAD. All three agencies accept complaints directly from workers at no cost, and you can file by phone, online, or in person using simple complaint forms. The agencies will investigate your complaint without requiring you to have legal representation. However, hiring an employment lawyer is highly advisable if: (1) the employer is large or sophisticated and likely to hire a lawyer to defend the case; (2) your case involves complex wage calculations or multiple years of violations; (3) you are fired or suffer serious retaliation after filing; or (4) the agency investigation stalls or the employer refuses to comply with the agency's orders. Most employment lawyers in Massachusetts work on contingency for wage and discrimination cases, meaning they take no upfront fee and are paid only if you win or settle your case (typically 25-33% of the recovery, plus expenses). Initial consultations are free. For cases that go to litigation, you may be responsible for court filing fees and expert witness costs, but the employer can be ordered to pay your attorney's fees if you win.
