At a convention in Trinidad in September 1913, United Mine Workers delegates from across the state endorsed a statewide strike, which became the greatest labor upheaval in Colorado history. Coal miners statewide accused operators of favoring profits over the safety of workers, and their demands included coal operators’ recognition of the union, an increase in wages of 10 percent, an eight-hour workday for all classes of labor in or around the coal mines, payment for deadwork, the right to have union-paid weigh bosses, the right of the miners to trade wherever they pleased (instead of company stores), the right to choose their own boarding place and their own doctor, the enforcement of the Colorado mining laws and “total abolition of the notorious and criminal guard system.”
