The AA engaged in a bitter strike at the Homestead works on January 1, 1882, in an effort to prevent management from including a non-union clause in the workers' contracts, known as a " yellow-dog contract". The AA organized the independently owned Pittsburgh Bessemer Steel Works in Homestead in 1881. It also acted as a hiring hall, helping employers find scarce puddlers and rollers. The union negotiated national uniform wage scales on an annual basis helped regulate working hours, workload levels and work speeds and helped improve working conditions.

As the mills expanded, the labor force grew rapidly, especially with unskilled workers. All of this greatly sped up the process of steelmaking, and allowed the production of vastly larger quantities of the product. Carnegie installed vastly improved systems of material-handling, like overhead cranes, hoists, charging machines, and buggies. In addition, the plant moved increasingly toward the continuous system of production. It now became possible to make steel suitable for structural beams and for armor plate for the United States Navy, which paid far higher prices for the premium product. labor history.Ĭarnegie Steel made major technological innovations in the 1880s, especially the installation of the open-hearth system at Homestead in 1886.

The final result was a major defeat for the union strikers and a setback for their efforts to unionize steelworkers. The dispute occurred at the Homestead Steel Works in the Pittsburgh-area town of Homestead, Pennsylvania, between the Amalgamated Association of Iron and Steel Workers (the AA) and the Carnegie Steel Company. The governor responded by sending in the National Guard to protect strikebreakers.
