International Unionisation
The largest trade union federation in the world is the Brussels-based International Trade Union Confederation (ITUC), which has approximately 309 affiliated organisations in 156 countries and territories, with a combined membership of 166 million. The ITUC is a federation of national trade union centres, such as the AFL-CIO in the United States and the Trades Union Congress in the United Kingdom. Other global trade union organisations include the World Federation of Trades Union.
National and regional trades unions organizing in specific industry sectors or occupational groups also form global union federations, such as Union Network International, the International Transport Workers Federation, the International Federation of Journalists or the International Arts and Entertainment Alliance.
