Founded by a group of Seattle theater janitors, SEIU Local 6 became one of the original locals of the Service Employees International Union in 1921. Today SEIU Local 6 represents more than 6,000 janitors, security officers, and allied industries workers in Washington state.
SEIU Local 6 members are janitors who clean office buildings in King, Pierce, Snohomish, and Spokane counties and security officers in downtown Seattle, Bellevue, and greater King County suburbs. SEIU Local 6 also represents retail workers, stadium workers, and barbers in other private sectors within our region.
SEIU Local 6 is part of the largest union in the country, Service Employees International Union, which represents over 2 million service workers in North America. SEIU is proud to have the most diverse membership and leadership in the Labor Movement. Immigrants make up a majority of SEIU6 membership and women of color hold many of our leadership positions.
