The United Farm Workers (UFW) union works to support the rights of farm workers. The UFW (originally the National Farm Workers Association) was co-founded by civil rights activist Cesar Chavez and women's rights activist Dolores Huerta in 1962. In the 1970s, the UFW became the recognized bargaining agent for approximately 50,000 farm workers and gained national support. The Aztec eagle on the button is the symbol of the UFW, and the three figures represent the farm workers.
