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 primary and fabricated metals, paper, chemicals, glass, rubber, heavy-duty conveyor belting, tires, transportation, utilities, container industries, pharmaceuticals, call centers and health care. 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. The current International President of the United Steelworkers is Tom Conway, who was installed as President after the retirement of Leo Gerard. Rank-and-file members, as well as representatives, of the United Steelworkers refer to themselves, and are most often referred to, as Steelworkers. The use of the capitalized single word Steelworker or Steelworkers, as opposed to the lowercase two-worded steel worker or steel workers, is also an identifier of those who are part of, or affiliated with, the United Steelworkers International Union rather than being general non-union workers within the steel industry. This distinction is important in North America wherein a vast majority of the steel industry is unionized. For example, some of the most recognizable and largest companies in the business such as United States Steel (USS) and Cleveland-Cliffs, with their combined hourly workforces at facilities in North America being Steelworkers and represented by the USW, including the largest facilities on the continent, like US Steel's Gary Works in Gary, Indiana, Cleveland-Cliffs's Burns Harbor in Burns Harbor, Indiana, Indiana Harbor East and West in Northwest Indiana, and Cleveland Plant in Cleveland, Ohio, all of which are situated on the Great Lakes freshwater system. On the other hand, some steel companies, usually at facilities known as "mini-mills", like Nucor Steel and its facility in Crawfordsville, Indiana, are non-union shops not represented by the United Steelworkers. Origins and history The USW was established May 22, 1942, in Cleveland, Ohio, through the Congress of Industrial Organizations (CIO) by a convention of representatives from the Amalgamated Association of Iron, Steel, and Tin
