Massachusetts Workers’ Compensation Law

Massachusetts Workers' CompensationNo matter how many employees you have in the state of Massachusetts, you need workers’ compensation coverage. The Massachusetts workers’ comp system helps protect both employees and employers.
For your employees, workers’ comp coverage provides benefits when they get a work-related injury or illness. For your business, workers’ comp limits your liability for workplace injuries or illnesses. Although, in a case of willful negligence by you, your business would not be protected from liability.1
Workers’ comp helps pay for any necessary medical care for work-related injuries or illnesses. It also helps partially compensate employees for lost wages after the first five calendar days of a disability.2
The Department of Industrial Accidents (DIA) administers Massachusetts workers’ compensation law. As an employer in Massachusetts, you have certain obligations under this law. Para más información, visite
