This study comparatively examines the relationship between revitalization strategies and trade union power resources in Central Eastern Europe. It shows that the post-2008 weakening of union power resources in the region served as a catalyst for a wide range of revitalization strategies, many of which included elements not documented in the revitalization literature. In most cases, union revitalization strategies involved the mobilization of organizational and societal resources and were geared towards (re)building statutory rights for unions and (re)establishing legal guarantees for workers. This ‘institutional longing’, however, left many organizations oblivious to membership decline, which may threaten their long-term survival.
