The British merger movement: the importance of the ‘aggressive’ unions

Union mergers in Britain are dominated numerically by transfers of engagements from minor unions to major unions. Just five major or acquiring unions were responsible for absorbing 79% of all transfers to TUC affiliated unions between 1978 and 1994. This study establishes the extent of this domination, examines the characteristics of the five unions’ aggressive merger policies and considers the consequences of the findings for theories of union mergers.
