The largest TCO affiliate is Unionen with 551,000 active members in 2018. TCO is independent and  not affiliated to any political party in Sweden. TCO is an affiliate of the European Trade Union Confederation and Eurocadres. History. TCO is the product of two confederations that merged in 1944. The older organisation was the Confederation of Employees ( or DACO) founded in 1931 by seven private sector white collar unions representing 20,000 workers. The second organisation was the Swedish Confederation of Professional Employees ( TCO) which was founded in January 1937 by eight public sector unions representing 38,000 workers. The two confederations merged in 1944, adopting the name TCO, bringing together 40 trade unions representing 180,000. After World War  II membership in the affiliated unions grew rapidly to more than half a million by 1965. Affiliates and membership.
