In Los Angeles, a joint labor action led by Local 99 of Service Employees International Union and United Teachers Los Angeles is planned to occur in the coming weeks. The three-day strike is expected to cause many schools in the city to shut down as the unions present a unified front to put pressure on the district. This joint strike is signficiant because attention usually focuses on teachers, but the Local 99 workers also serve essential functions for both the students and the district working as bus drivers, cafeteria workers, and janitors. Conflicts regarding contract negotiations and claims of unfair practices by the district like threats and interrogations have prompted this labor action, and the unions are seeking pay increases to match increasing costs of living and the essential nature of their job functions.
