César Chávez was a Mexican-American labor leader who used non-violent methods to fght for the rights of migrant farm workers in the southwestern USA. Migrant farm workers are people who do farm labor, moving from farm to farm and from town to town as their work is needed - it is diffcult work that pays very little and can be dangerous due to the use of pesticides (pesticides are chemicals that kill bugs and can make people sick). Chávez founded a group that advocates for the rights of farm workers, demanding to increase wages and improve the working conditions and safety of farm workers. He also organized strikes (when workers refuse to work until improved working conditions and salary demands are met)and nationwide boycotts of agricultural products in order to help workers (a boycott is a protest in which the public is asked not to buy certain products).
