What organization did Cesar Chavez help to form in his efforts to improve labor conditions?

Cesar Chavez was instrumental in advocating for the rights and working conditions of farmworkers, and he co-founded the United Farm Workers Union (UFW) in 1962. The UFW aimed to improve labor conditions, secure better wages, and provide workers with essential rights and benefits. Chavez's leadership and activism were crucial in organizing agricultural laborers, particularly in California, where he led successful strikes and boycotts to draw attention to their plight.

The United Farm Workers Union became a significant force in the labor movement, bringing together farmworkers to collectively negotiate for improved working conditions. Through efforts such as the historic Delano grape strike, Chavez and the UFW highlighted the exploitation faced by migrant workers and advocated for justice, gaining national recognition and support for their cause. Thus, the United Farm Workers Union effectively symbolizes Chavez's commitment to labor rights and social justice, making it the clear answer to the question about his contributions to improving labor conditions.
