« The book presents the findings of a four-year study of the challenges facing trade unions and their responses in ten west European countries. The project involved a substantial number of interviews with key union representatives and academic experts in each country, together with the collection of a large amount of union documentation and background material. The book gives an account of trade unionism in each country, the main recent challenges that unions have faced, and responses in terms of recruitment and mobilisation; organizational restructuring; new approaches to collective bargaining; changing political strategies; and international activities. The analytical starting point is that trade unions are conservative institutions containing significant veto points to organizational change, but at the same time can display dynamism and innovation, and that external challenges can therefore stimulate important internal adaptation. The book engages with the debates of the past two decades on union modernization and revitalization, and more generally with theories of institutional change and with the literature on varieties of capitalism. The central theme is that while trade unions do not easily change identities and core practices, they are not locked into inertia. Trade unions are not unitary actors but are internally contested organizations, and internal conflict is itself a potential source of dynamism. The literature on "revitalization" has tended to divide between the over-optimistic and the over-pessimistic; this study presents a more nuanced and differentiated account. In particular, it attempts to identify some of the key internal and external conditions for effective strategic innovation. »--
