Public Sector

SEIU 509 represents over 9,000 Massachusetts state workers who are dedicated to supporting individuals and families across the Commonwealth navigate the complexity of public services. They connect them to critical resources, provide case management, and advocate for their clients. Public sector workers uphold the social infrastructure and safety net for the most vulnerable communities in our state.
