From the perspective of gender theory, the intersections among gender, class, and race make it difficult, if not impossible, to assign political issues and identities to just one social movement. Instead, the negotiation of movement ownership of issues and identities occurs through interaction among social movements, including interactions that create denial and distance. This article takes the interaction of labor organizing and feminism as the lens for studying movement interaction at three levels: opportunity structure, organizing practices, and framing ideas. Using (...) a case study of a strike of day care workers in West Berlin in the winter of 1989-90, it contrasts inclusive and exclusive forms of solidarity and their consequences for organizational practices. This particular strike received little support from either feminists or the labor movement and eventually failed, an outcome that can be seen as reflecting the weakness of structural and organizational supports for frames favoring inclusive solidarity.
