The United Steel, Paper and Forestry, Rubber, Manufacturing, Energy, Allied Industrial and Service Workers International Union, commonly known as the United Steelworkers (USW), is a general trade union with members across North America. Headquartered in Pittsburgh, the United Steelworkers represents workers in Canada, the Caribbean, and the United States. The United Steelworkers represent workers in a diverse range of industries, including its original home in metals, as well as paper, chemicals, glass, rubber, heavy-duty conveyor belting, tires, transportation, utilities, container industries, pharmaceuticals, call centers, museums, health care, and higher education.
The United Steelworkers is currently affiliated with the AFL–CIO in the United States and the Canadian Labour Congress (CLC) in Canada as well as several international union federations. On July 2, 2008, the United Steelworkers signed an agreement to merge with the United Kingdom and Ireland–based union Unite to form a new global union entity called Workers Uniting.
As of 2023, the International President of the United Steelworkers is David McCall, who was installed as president after the death of Tom Conway.
The founder and first president of the USW, Philip Murray, led the union through its first organizing drives and its first decade, when the workers of USW went on strike several times to win the right to bargain collectively with steel companies.
Significant job actions of the USW include:
- 1946 US Steel Strike
- 1952 steel strike
- Steel strike of 1959
- 1974 Elliot Lake miners strike
- Steel strike of 1986
