The merger of two or more trade unions either through a ‘transfer of engagements’, in which a smaller union is absorbed in a larger union, or through the creation of a new trade union. In Britain, UNISON was formed in 1993 from the merger of three previously separate public service unions, whilst Unite was created in 2007 by the merger of Amicus and the Transport and General Workers' Union. Researchers have identified three types of union merger. Defensive mergers are a response to membership decline, consolidatory mergers occur when two unions operating in the same industry decide to pool their strength, and aggressive mergers occur when growing unions take over smaller organizations in order to enter a new job territory. In recent years, there has been extensive merger activity amongst unions in Germany, the UK, and the USA, which has led to the emergence of larger, general unions with members in a broad range of occupations and industries.
