List of TGWU amalgamations
The Transport and General Workers Union (TGWU) was created in 1922 from a merger of fourteen unions and continued to grow through a series of mergers, amalgamations and transfers of engagements. This process, which is recorded below in chronological order, continued through to 2007 when the TGWU itself merged with Amicus to form a new union called UNITE.
