A trade union is an organisation consisting of a combination of wage-earners engaged in the same industry or trade, usually to provide negotiating power with the employer and as a mutual self-help group for employees when they need financial assistance or legal assistance connected with their employment.
In the USA, these associations of workingmen, for concerted action upon questions of wages, hours of labour and for mutual relief, were begun in 1852 by the formation of the International Typograpliical Union, followed in 1859 by the Machinists' and Blacksmiths' International Union, and the Iron Moulders' Union of North America. The Brotherhood of Locomotive Engineers was organized in 1863, the Journeymen Tailors' National Trades Union in 1865, the Coopers' International Union in 1870, the Cigarmakers' International Union about the same time, the Miners' National Union in 1873.
