The Congress meets every fourth year. The Executive Committee, which is elected by the Congress, is responsible for TCO’s ongoing operations.
The decisions of the Executive Committee are carried out by TCO’s Central Office. The Executive Committee consists of representatives from all of TCO:s affiliates.
There are TCO Councils throughout Sweden in which the unions co-operate on regional and local issues, above all in the labour market and educational fields. A TCO Council may, for example, cover a municipality or a county. Students in higher education are also entitled to join a trade union. The unions affiliated to TCO together have over 90 000 student members.
