FAQ

Frequently Asked Questions About Workplace Safety in Massachusetts

I think there are safety hazards or risks at my workplace. How do I report an unsafe workplace in Massachusetts?

If you believe your workplace is unsafe, you have the right to speak up.

Private Sector Workers

If you work for a private company, you can file a confidential complaint with OSHA.

🔗

OSHA Complaint Form: https://www.osha.gov/workers/file-complaint

Can I report a workplace hazard anonymously?

Yes, in many cases.

Both OSHA and DLS typically ask for contact information so they can follow up, but your identity can often be kept confidential from your employer.

If you are worried about retaliation or fear speaking up, MassCOSH can help you explore your safest options.

  • Making illegal paycheck deductions
  • Misclassifying you as a contractor
  • Discriminating based on race, gender, pregnancy, religion, disability, or national origin
