"Social networks represent one possible trade union response to cross-border industrial restructuring. The aim is to bring together independent actors so as to generate interaction, cooperation and coordination of cross-national practices and integration of policies. This article draws on empirical evidence from four sectors. It first examines whether unions make effective use of the Internet when developing networking and coordination activities to respond to transnational change in Europe. Second, it discusses the reasons for cross-sectoral variation in the use of virtual networking. It is argued that the use of the Internet by European unions becomes a matter of strategic choices and politics, and reflects sector-based differences in the way that transparency, coordination, social cohesion and democracy are secured for representation and bargaining purposes among employees and unions across borders."
