At the end of the 1930s, “folk tourism” began to be promoted in Finland and it was considered that even poorer families have the right to holiday. In 1941, a new annual leave law came into force, bringing more free time to employees. In the same year, the Finnish Holiday Association was founded, and its name was shortened in 1944 to the Holiday Association.
The holiday union was based on large trade unions such as SAK, Akava and the largest trade union, STTK. In addition, municipalities and social and health organizations were involved.
After the wars, the Holiday Association began to organize hotel and spa holidays for its members on social grounds, the costs of which were partly taken care of by the Slot Machine Association.
