Norwegian Union of Iron and Metalworkers

The Norwegian Union of Iron and Metalworkers (, NJMF) was a trade union representing workers in the metal industry, workshops, and shipbuilding in Norway.
The union was founded in 1891, and in 1905 it joined the Norwegian Confederation of Trade Unions. In 1907, it came to the country's first collective agreement, with the National Association of Mechanical Workshops. In 1960, the union absorbed the Norwegian Union of Foundry Workers, followed in 1985 by the Norwegian Union of Gold Workers. By 1987, it had 97,998 members.
In 1988, the union merged with the Garment Workers' Union, the Norwegian Union of Building Industry Workers, the Norwegian Union of Paper Industry Workers and the Norwegian Union of Forestry and Land Workers to form the United Federation of Trade Unions.
