A clip from the 1959 documentary "Factory Farms" describing unfair labor practices for braceros in the US. Runtime: 6:15
The bracero program was an agreement between the governments of the United States and Mexico designed to fill agriculture and railroad maintenance labor shortage in the US created by the Great Depression and World War II. The program, which saw approximately 4.6 million Mexican laborers, or braceros, admitted to the US on a temporary basis, ran from 1942-1964.
According to the Bracero History Project (https://braceroarchive.org/), "the Bracero Program was controversial in its time. Mexican nationals, desperate for work, were willing to take arduous jobs at wages scorned by most Americans. Farm workers already living in the United States worried that braceros would compete for jobs and lower wages. In theory, the Bracero Program had safeguards to protect both Mexican and domestic workers for example, guaranteed payment of at least the prevailing area wage received by native workers; employment for three-fourths of the contract period; adequate, sanitary, and free housing; decent meals at reasonable prices; occupational insurance at employer's expense; and free transportation back to Mexico at the end of the contract. Employers were supposed to hire braceros only in areas of certified domestic labor shortage, and were not to use them as strikebreakers. In practice, they ignored many of these rules and Mexican and native workers suffered while growers benefited from plentiful, cheap, labor. Between the 1940s and mid 1950s, farm wages dropped sharply as a percentage of manufacturing wages, a result in part of the use of braceros and undocumented laborers who lacked full rights in American society."
The bracero program had long-ranging effects on US immigration policy, race relations, and wage growth, and the conditions endured by braceros gave rise to many labor organization efforts. As the program ended, many labor unions emerged including the National Farm Workers Association (NFWA) led by César Chávez and Dolores Huerta and the Agricultural Workers Organizing Committee (AWOC), which merged in 1966 to become the United Farm Workers (UFW).
