A major event that showcases a turning point in the labor rights movement in the U.S. was the Triangle Shirtwaist Factory fire in 1911. This tragedy highlighted the dire working conditions and lack of safety regulations faced by workers, particularly women and immigrants. In the aftermath, public outrage led to significant reforms in labor laws, including improved safety standards and workers' rights. The fire served as a catalyst for the creation of labor unions and greater organizational efforts to push for workers' rights, ultimately influencing legislation such as the Fair Labor Standards Act of 1938.
