Which organization was involved in the Pullman Strike besides the workers?

• A. American Railway Union
• B. Knights of Labor
• C. International Ladies' Garment Workers Union
• D. American Federation of Labor

Answer: (A)

The key idea is how a national union can mobilize workers across an industry to create nationwide disruption. In the Pullman Strike, the American Railway Union, led by Eugene V. Debs, organized a broad, across-the-board boycott of trains carrying Pullman cars and urged sympathy strikes by other railway workers. This turned a local grievance at a single plant into a national action that affected interstate commerce, drawing a strong response from the federal government. The Knights of Labor were not the central organizing force for this event, and the American Federation of Labor did not lead the strike either. The garment workers union listed as an option hadn’t formed yet.
