SEIU Wisconsin

SEIU Wisconsin

In 2023, several SEIU locals merged into a single organization called SEIU Wisconsin.

That merger brought together:

  • SEIU Local 152

  • SEIU Local 1 (Wisconsin members)

  • SEIU Healthcare Wisconsin

SEIU Wisconsin is based in Madison, WI, and is part of the much larger Service Employees International Union (SEIU). The union represents about 2,000 members who are health care workers, janitors/building workers, and school support staff.

The union deducts 1.65% of a member’s biweekly or monthly wages in dues, automatically taken from their paycheck. Calculate your potential union dues.

The union is free to do what it wants with the money it collects from members without their approval.

Union members are expected to abide by SEIU Wisconsin’s bylaws and the Service Employees International Union’s constitution. You are allowed (and encouraged) to ask the union questions regarding their rules and procedures.
