[Excerpt] The revitalization perspective is hardly new. With deep roots in both labor movement history and industrial relations research, such work was marginalized for much of the postwar period both in union strategy and in the field of industrial relations. What is new is the rather sudden arrival of revitalization research in the mainstream of industrial relations along with a broader literature on contentious politics in a global economy (e.g., Klein, 2002; Delia Porta & Tarrow, 2004). This introductory article offers an overview of the revitalization perspective, deepened in relevance by contemporary struggles for democratic representation in the modern workplace and beyond.
