Unemployment Insurance (UI) for Employers

As an employer, you may be subject to unemployment insurance. Learn about your responsibilities.

Employers like you play an important role in providing unemployment insurance (UI) benefits to Massachusetts workers. UI benefits offer workers temporary income protection and professional support during periods of unemployment and uncertainty.
Employers fund the UI program, and serve as a resource for unemployed workers seeking UI benefits. The Department of Unemployment Assistance (DUA) manages the UI program, and is committed to helping you understand the Massachusetts unemployment insurance law.
