The Swedish Factory Workers' Union (Swedish: Svenska Fabriksarbetareförbundet, Fabriks) was a trade union representing manufacturing workers in Sweden.
In 1895, it began admitting workers from across the country, moving its headquarters to Stockholm, and renamed itself as the Swedish Heavy and Factory Workers' Union.
[1] The union had only 419 members on formation, but grew rapidly, to reach 47,267 by 1907.
Over the following decades, membership declined slightly, falling to 71,958 by 1992, at which time, 96% of its members worked in the chemical industry, 3% in personal services, and most of the remainder in quarrying.
The following year, it merged with the Swedish Textile, Garment and Leather Workers' Union, to form the Swedish Industrial Union.
