Your Union Dues


Q:  What do dues pay for?

A:  By becoming a part of SEIU Local 509 (11,000 members in Massachusetts) and the Service Employees International Union (over 1.9 million members across the United States and Canada), you will have a large staff and a wealth of resources at your disposal. 
You will have an experienced staff person to work with you, and you will be able to tap into a wide range of expertise: for contract language, health & safety information, legal staff, the support of a larger labor movement, a research department, steward training, problem-solving strategies, and so much more. 
All these resources are paid for entirely by members' dues.  The Local's budget is set by the Joint Executive Board, an elected body of rank and file union members representing all the different parts of the Union.
