The organization faced 15 Washington building trades unions representing some 29,000 workers that, as of 1966, had only seven non-white apprentices, according to the Washington State Board of Discrimination. The CCA put aside litigation strategies and used direct action to effect change. According to Trevor Griffey, the organization
"brought every major, federally funded construction site in the city of Seattle to a halt in late August and September of 1969. They did this -- as other activists were doing in Pittsburgh, Philadelphia, and Chicago at roughly the same time -- by disabling equipment, blocking workers from their jobs, and demanding that federal civil rights law be used to force unions to hire more black workers" (Griffey).
