Final answer:
The Homestead Strike resulted in a setback for labor as workers faced wage cuts and a defeated union at Carnegie's Steel Mill.
Step-by-step explanation:
The Homestead Strike of 1892 was a significant event in labor history precipitated by wage cuts at Andrew Carnegie's Homestead Steel Mill. Management, under Henry C. Frick, looked to crush the Amalgamated Association of Iron and Steel Workers union and hired Pinkerton guards to face the striking workers.
The ensuing violence left many dead and eventually led to the union's defeat. Workers eventually returned to their jobs under reduced pay and longer shifts, demonstrating a setback for labor movements at the time.
