International Metalworkers' Federation
The International Metalworkers' Federation (IMF) was a global union federation of metalworkers' trade unions, founded in Zürich, Switzerland in August 1893.  the IMF had more than 200 member organisations in 100 countries, representing a combined membership of 25 million workers. History 
The federation was founded as the International Metallurgists' Bureau of Information. In 1904, the International Secretariat of Foundry Workers merged into the federation, which renamed itself as the "International Metalworkers' Federation". From 1921, its constitution called for not only international co-operation to improve wages and conditions, but also for workers to take over the means of production. Membership of the federation reached 1.9 million in 1930, but fell to only 190,000 in 1938, hit by the international depression. By 1947, membership had reached a new high of 2.7 million, and the federation took a leading role in opposing the World Federation of Trade Unions, instead becoming a founding constituent of the International Confederation of Free Trade Unions. The organization held a congress every four years, consisting of delegates from the member organisations. The congress established the broad lines of the IMF's policies and actions and elected the President and General Secretary of the IMF. Some member unions wished for the federation to hold sectoral conferences, and the IMF's refusal to do so led six unions to found the International Federation of Foundry Workers in 1949, but this was dissolved in 1954. The international headquarters of IMF was based in Geneva, Switzerland. There were regional offices in Johannesburg, New Delhi, Kuala Lumpur, Santiago, Mexico City, and a project office in Russia. In June 2012, the IMF merged into the new global federation IndustriALL Global Union. Affiliates
