This article considers what a transnational, and specifically European labour
movement, would mean in the context of European integration, and whether there
are prospects for its development. There are certainly structures and sporadic
actions, so the question is whether they can develop further into a movement. I
will summarize the literature on the integration of labour in the EU, which
commonly argues that it is divided and incapable of action. These obstacles can
be considered in a different light when the strand of social movement approaches
is applied. Then I will present two cases of transnational European collective
action with a focus on the managing of difference and on developing into a
social movement. To summarize I will assess the future of labour mobilization in
transnational context and conclude with a tentative explanation.
