César Chávez accomplished the impossible. He formed a union of agricultural workers, the United Farm Workers union (UFW). Organizing an international boycott of table grapes, he sustained his effort over five years with long fasts, huge marches, determined, almost fanatical organizers, and extensive alliances with urban supporters and civil rights groups. Chávez won contracts with the entire California table grape industry and seemed on the way to unionizing all of California’s farmworkers, and from there towards building a nation-wide union. Since 1973, the UFW has steadily declined. Weakened by internal union problems, thwarted by the systematic gutting of the Californa State Agricultural Labor Relations Board, and losing valuable leaders, and undermined by a continual influx of desperate, undocumented immigrant workers, Chávez saw union membership drop from over 100,000 in 1979 to around 15,000 today.
