Dying for Work in Massachusetts: Loss of Life & Limb in Massachusetts Workplaces

Dying for Work 2026 is MassCOSH and the Massachusetts AFL-CIO’s annual Workers’ Memorial Day report documenting 59 work-related injury deaths in Massachusetts in 2025—a 22.9% increase from 2024—and connecting those losses to weakened federal enforcement, climate-driven hazards, immigration retaliation, and specific policy fixes. The 76-page booklet is both a memorial record and an advocacy roadmap spanning construction accountability, transportation safety, maritime labor abuse, heat standards, and 2026 State House priorities.

As a result of Robert Higgins and Kelvin Mattocks, employees of Atlantic Drain Service Co., killed on Oct. 21, 2016, when the trench in which they were working collapsed and filled with water, we were able to secure an executive order in Boston preventing contractors from obtaining permits if they have outstanding OSHA violations.

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