“…A strong labour movement and mobilization are often seen as a desirable outcome and necessity for defending labour rights in the transnational context (Tilly, 1995). Mass mobilization at EU level is thus deemed to be of crucial importance for the success of interest-group lobbying (Rucht, 2001;Tarrow, 2001;Turner, 1996) and social dialogue at the EU level (Hyman, 1994). It is also a common argument that international solidarity needs to be entrenched in the lower ranks of the trade unions (Ebbinghaus and Visser, 1996;Gobin, 1994;Hyman, 2001;Waterman, 1998), and hence that trade unionism in the EU should 105 incorporate the characteristics of a social movement to be effective (Hyman, 2005).…”
