In this clip from Red Metal: The Copper Country Strike of 1913, learn about the early days of the strike at the Calumet & Hecla copper mines in Calumet, Michigan, including Union tactics to keep the mines shut down and the mining company’s response. The strike, which began in late July 1913, lasted more than nine months, was the first in the copper belt of Michigan’s Upper Peninsula. This clip discusses the importance of the presence of a Union for an effective strike, women’s participation in strike activities, as well as the harsh response of Calumet & Hecla’s management: “The union must be killed at all cost.”
