This study examines the intersection of individual life-histories, organisational histories and societal histories and reveals how religion, in several different expressions, serves to provide a connection between justice for workers and justice for the environment in the work of trade unionists. The trade union movement is generally seen as secular, and thus in our life-history interviews finding religion as a backdrop to labour activists' formation was unexpected. Religion becomes manifest in various ways, partly through experiences in the present or at (...) formative periods in unionists' lives, but also through its cultural embeddedness in language and collective memory. In this way it serves to provide subtle influences on beliefs, concepts of social justice and daily action. (shrink)
