During the major economic depression of the early 1890s, the Pullman Palace Car Company cut wages in its factories. Discontented workers joined the American Railway Union , led by Eugene V. Debs, which supported their strike by launching a boycott of all Pullman cars on all railroads. ARU members across the nation refused to switch Pullman cars onto trains. When these switchmen were disciplined, the entire ARU struck the railroads on June 26, 1894. Within four days, 125,000 workers on twenty-nine railroads had people quit work rather than handle Pullman cars.  Strikers and their supporters also engaged in riots and sabotage. The railroads were able to get Edwin Walker, general counsel for the Chicago, Milwaukee, and St. Paul Railway, appointed as a special federal attorney with responsibility for dealing with the strike. Walker went to federal court and obtained an injunction barring union leaders from supporting the boycott in any way. The court injunction was based on the Sherman Anti-Trust Act which prohibited "Every contract, combination in the form of trust or otherwise, or conspiracy, in restraint of trade or commerce among the several States". Debs and other leaders of the ARU ignored the injunction, and federal troops were called into action. The strike was broken up by United States Marshals and some 2,000 United States Army troops, commanded by Nelson Miles, sent in by President Grover Cleveland on the premise that the strike interfered with the delivery of U.S. Mail. During the course of the strike, 13 strikers were killed and 57 were wounded. An estimated $340,000 worth of property damage occurred during the strike. Debs went to prison for six months for violating the federal court order, and the ARU disintegrated.. Why were Pullman Palace Car Company workers discontented?
