Answer:
The reason for this dispute was proposed cuts to wages for workers at the Homestead plant.
Henry Clay Frick, the acting manager of the Homestead plant, proposed a 22 percent cut to wages for workers. This was due to tough economic times for the company. This cut to wages angered workers, as they would not make enough money to support their families. This resutled in a heated dispute between the factory workers and management. After violence broke out between the union workers and the Pinkertons, the state government sent in troops to keep the peace between the two conflicting parties.
