Final answer:
During the 1960s, Cesar Chavez's actions improved conditions for Mexican American agricultural laborers through the United Farm Workers organization.
Step-by-step explanation:
During the 1960s, the actions of Cesar Chavez led to improved conditions for Mexican American agricultural laborers.
Cesar Chavez, along with Dolores Huerta, founded the United Farm Workers (UFW) in 1962 to fight for the rights of migrant workers. They used tactics such as strikes, boycotts, and marches to demand better pay, benefits, and working conditions for farm workers. Chavez's efforts resulted in the signing of contracts by California grape producers in 1970, which provided workers with improved pay and benefits. Ultimately, Chavez's work with the UFW benefited thousands of Mexican American agricultural laborers across the country.
