Labor movements played a critical role in shaping modern worker rights by advocating for better conditions, fair wages, and the right to organize. Beginning in the late 19th century, these movements challenged oppressive labor practices, leading to significant reforms through strikes, protests, and political lobbying. Key victories included the establishment of the eight-hour workday, minimum wage laws, and workplace safety regulations. As labor unions gained strength, they contributed to the formation of a more equitable and just society, transforming the role of workers in the economy.
