CIO (Congress of Industrial Organizations)

The CIO, or Congress of Industrial Organizations, was a major American labor organization formed in the 1930s. It aimed to unite workers across various industries to better advocate for their rights, improve working conditions, and secure fair wages. The CIO focused on organizing unskilled and semi-skilled workers, which differentiated it from other labor groups at the time. Its aggressive tactics and successful strikes helped strengthen the labor movement in the United States. The CIO eventually merged with the American Federation of Labor (AFL) in 1955, forming a larger federation that represents various trade unions.
