# International Federation of Building and Wood Workers

The International Federation of Building and Wood Workers (IFBWW) was a global union federation of trade unions in the building, building materials, wood, forestry and allied industries.

## History

The federation was established in 1934 by a merger of the International Federation of Building Workers and International Federation of Wood Workers. The International Secretariat of Stone Masons and the International Secretariat of Painters and Allied Trades later joined the organisation. As of 2005, it had 287 member organisations in 124 countries, representing a combined membership of more than 10 million workers.
The IFBWW was based in Geneva and had a network of regional offices. The organisation worked closely with the International Trade Union Confederation (ITUC) and the other global union federations, and had Special Consultative Status at the Economic and Social Committee of the United Nations.
The IFBWW held a congress every four years, consisting of delegates from the member organisations. The congress established priorities and strategy for the organisation, and elected the Executive Committee. which met immediately before and after the congress, and at the midpoint of the congress period. As supreme governing body during the intercongress period, it was responsible for all policies and operations of the IFBWW. The Executive Committee appointed a Management Committee, which was responsible for the administration of the IFBWW and for the implementation of its policies.
At its congress in Buenos Aires on 9 December 2005 the IFBWW merged with the World Federation of Building and Wood Workers (WFBW) to create a new joint global union federation, the Building and Wood Workers' International.
