The International Federation of Trade Unions of Transport Workers (, FIOST) was an International Trade Federation affiliated to the World Confederation of Labour (WCL).
History
The federation was established in 1921 at a conference in Lucerne, as the International Federation of Christian Trade Unions of Railway, Tramway and Other Transport Workers. In 1955, it renamed itself as the International Federation of Christian Trade Unions of Transport Workers, and then in 1970 it dropped "Christian", to assume its final name.
In 2006, the WCL merged into the new International Trade Union Confederation, and FIOST dissolved, its former affiliates mostly joining the International Transport Workers' Federation.
The federation had four sections, covering aviation, railways, waterways, and road transport.
