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 SEIU6 Property Services NW represents more than 7,000 janitors, security officers, airport passenger service workers and allied industries workers in Washington state.
SEIU6 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. SEIU6 also represents retail workers, stadium workers, and barbers in other private sectors within our region.
SEIU6 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.
