Compared to other workers, organization attempts on the behalf of farm-workers face a double challenge. First, labor laws that apply are not always enforced for agricultural workers. The National Labor Relations Act of 1935, for example, which protects most workers who organize and form trade unions from employer retaliation (e.g., the firing of workers for trying to join a union) and sets up a framework for unions and employers to negotiate in good faith, does not extend to farm workers Similarly, the Fair Labor Standards Act of 1938, which sets minimum wage and overtime pay requirements does not apply to farm labor. In 1966, the minimum wage requirement, but not the overtime pay, was extended to apply to farm workers who worked on farms where there was over approximately 7 full-time employees in a quarter.
