Suing Over a Work Injury in Massachusetts

When Massachusetts law lets an injured worker sue the employer, suing a third party such as a driver or equipment maker, and what to do if the employer has no workers' comp.

Short answer: A worker who does not give the employer written notice at the time of hire (or within 30 days after the employer becomes insured) that he or she claims the right to sue is held to have waived the right to sue the employer at common law for a compensable injury; G.L. c. 152, §§24, 66

Suing your employerA worker who does not give the employer written notice at the time of hire (or within 30 days after the employer becomes insured) that he or she claims the right to sue is held to have waived the right to sue the employer at common law for a compensable injury; the worker's family is likewise held to have waived claims against the employer. A worker who did reserve the right may later waive it in writing. If the employer is uninsured, the worker may sue the employer and the employer loses the usual defenses.

Suing someone other than your employerIf someone other than the insured employer is legally liable, the worker gets workers' compensation without having to choose, and either the worker or the insurer may sue the third party; the insurer may not sue until compensation has been paid and 7 months have passed since the injury. The recovery goes first to the insurer up to what it paid, and the worker keeps any excess; attorney's fees and interest are shared in proportion to amounts received. Settlements with the third party (other than during trial) need approval of the board, the reviewing board or the court after a hearing.
If your employer has no workers' compThe Workers' Compensation Trust Fund pays approved claims against employers who are uninsured in violation of the law, if the worker is not entitled to benefits in another state, and may then recover from the uninsured employer. A worker may also sue the employer for damages within 20 years after learning the injury was work-related, and in that suit the employer cannot defend by blaming the worker's or a co-worker's negligence, assumption of risk, or lack of employer fault.
