Several thousand new trade union recognition agreements have been signed since 1997, representing a major development within industrial relations in Britain. This has resulted from the interaction of union organizing efforts and the statutory union recognition provisions of the Employment Relations Act 1999. However for trade unions, recognition alone is not enough, a vital issue is whether, having gained union recognition, trade unions are now effectively delivering upon the promises and prospects of union recognition.These essays examine the substantive outcomes of these new agreements in regard to union representation and collective bargaining. In particular, they explore:the impact on terms and conditions of employmentemployers’ behaviour and strategythe nature of the union-management bargaining relationshipthe building of workplace unionism. While the collection focuses primarily on Britain, the germane issues are also looked at in the context of Australia, Canada and the U.S.A. Conceptually and theoretically, Union Recognition offers contributions which develop our understanding of the relationship between workplace and national unionisms and of mobilization theory.
