United Mine Workers of America. District 22

The United Mine Workers of America (UMWA), a labor union representing coal miners and other workers, was founded in Columbus, Ohio, in 1890. The UWMA began recruiting members in Wyoming in the early 1910s when District 22 of the organization was formed out of 54 local unions in Wyoming and Utah. The district headquarters were located in Cheyenne, Wyoming, until 1941 when they were relocated to Rock Springs, Wyoming. The UMWA was closely affiliated with other labor groups in Rock Springs, Sweetwater County, Wyoming. The Rock Springs Central Labor Union (RSCLU) served as an umbrella organization for these organizations, which included unions representing miners, electricians, barbers, painters, culinary and laundry workers and auto mechanics. The RSCLU was preceded by the Sweetwater County Federated Trades and Labor Council (SCFTLC) which was formed around 1915. The SCFTLC helped to establish the Rock Springs Cooperative Society (RSCS) to conduct a cooperatively owned and managed general mercantile business in Rock Springs. The business apparently lasted from 1917 until around 1918.
