c) The National Labor Union

The National Labor Union, formed in 1866, was an influential labor organization that played a crucial role in advocating for workers’ rights during the Reconstruction era. As one of the first national labor federations in the United States, it brought together diverse labor interests to address key issues facing workers. The union focused on demands for an eight-hour workday, better working conditions, and workers’ rights to organize. Although it dissolved in the 1870s, the National Labor Union laid important groundwork for future labor movements and helped bring workers’ issues to the forefront of national discourse during a critical period of American industrialization and reconstruction.
