A Mexican American, Chavez became the best known Latino American civil rights activist, and was strongly promoted by the American labor movement, which was eager to enroll Hispanic members. His public-relations approach to unionism and aggressive but nonviolent tactics made the farm workers' struggle a moral cause with nationwide support.
By the late 1970s, his tactics had forced growers to recognize the UFW as the bargaining agent for 50,000 field workers in California and Florida. However, by the mid-1980s membership in the UFW had dwindled to around 15,000.
After his death he became a major historical icon for the Latino community, organized labor, and liberal movement, symbolizing support for workers and for Hispanic power based on grass roots organizing and his slogan "Sí, se puede" (Spanish for "Yes, it is possible" or, roughly, "Yes, it can be done"). His supporters say his work led to numerous improvements for union laborers. His birthday, March 31, has become Cesar Chavez Day, a state holiday in California, Colorado, and Texas. -wikipedia
