Response:
The union workers opposed the growers. They fought strongly against the treatment of farm workers. They advocated for the farmers' rights, assisting them in overcoming poverty and unfair practices by raising awareness about the need for better working conditions (including fair wages and benefits).
Clarification:
Cesar Chavez was a labor organizer and a Mexican American union leader. Much of his life was dedicated to advocating for farm workers' rights. His motivation stemmed from experiences in his youth, witnessing the exploitation of workers, including child labor on farms. Many farm workers suffered premature deaths due to inadequate nutrition and abysmal living conditions.
This realization prompted Cesar Chavez to create a union focused on countering the growers. Initially called the "National Farm Workers Association," it was later renamed to "United Farm Workers." His aim was to dismantle the oppressive farm labor system, ensuring fair treatment for farmers, similar to other individuals. This inspired hope among farm workers and compelled the growers to implement certain reforms.
