Today in Labor History December 1, 1912: The rustling card system was put into place by the Anaconda Mining and Smelter Company. Rustling cards verified employees’ identities and employment status. The company used spies to identify union agitators and refused them rustling cards and jobs. In 1920, the IWW called a strike at the mines around Butte. They demanded the end of the rustling cards system, and the implementation of the 8-hour day and higher wages. On 4/21/1920, guards opened fire on unarmed picketers, killing one and injuring sixteen. Dashiell Hammett depicted the strike in his first novel, “Red Harvest.”
