The Swedish Forest Workers' Union (Swedish: Svenska Skogsarbetareförbundet, SSAF) was a trade union representing timber and forestry workers in Sweden.
Originally based in Sollefteå, it moved its headquarters to Gävle in 1920.
The following year, it affiliated to the Swedish Trade Union Confederation.
The early 1930s proved a particularly successful period, with the majority of members gaining coverage by collective agreements.
[1] In 1957, the union absorbed the small Swedish Timber Surveyors' Association, and in 1962 it adopted its final name, but membership was in long-term decline and by 1997 was down to only 12,160.
