Congress of Industrial Organizations

The Congress of Industrial Organizations (CIO) was a significant labor union group formed in the 1930s to organize workers in various industries, particularly those with unskilled labor, such as steel and automotive manufacturing. It aimed to improve workers' rights, wages, and working conditions through collective bargaining. The CIO played a crucial role in expanding union membership and advocating for labor laws in the United States. It eventually merged with another major labor group, the American Federation of Labor (AFL), in 1955, creating a more unified labor movement. The CIO remains influential in labor history and worker advocacy.
