The California School Employees Association, AFL–CIO (CSEA) is the largest classified school employees labor union in the United States. CSEA represents a quarter million classified public school employees in California. CSEA was formed in 1927 by a determined group of Oakland custodians who saw the need to gain protections for themselves and other classified employees. Through this initial determination, CSEA proved to be an organization that has stood the test of time. CSEA is an affiliated member of the AFL–CIO. From Wikipedia
