Final answer:
The National Farm Workers Association, co-founded by Cesar Chavez and Dolores Huerta, used tactics such as labor strikes, consumer boycotts, and marches to gain rights for farm workers. Their concerted efforts culminated in the recognition of the UFW by grape growers in 1970, leading to improved labor contracts.
Step-by-step explanation:
The National Farm Workers Association (NFWA), later known as the United Farm Workers (UFW), employed several tactics to advance their demands during the farm labor movement led by Cesar Chavez. These tactics included:
- Organizing labor strikes, which were actions where workers stopped working to call attention to their plight.
- Implementing consumer boycotts, notably the nationwide boycott of California grapes to pressure growers into recognizing the UFW and improving pay and benefits.
- Marching, as demonstrated by the 300-mile walk to Sacramento in 1966 to bring widespread attention to farm workers' issues.
These actions, combined with the solidarity shown with other ethnic groups such as the Filipino farm workers, and the strategic use of media and public support, brought significant advancements for farm laborers, leading to contractual agreements with grape growers in 1970 that recognized the UFW and improved working conditions and pay for farm workers.
