Based on two qualitative case studies undertaken in Switzerland, this article compares the positioning of Climate Strike activists and construction workers on questions of climate change, so as to analyse the impact of work practices on environmental orientations. Building on a praxeological approach, the article argues that communities of practice in workplaces and educational institutions influence environmental orientations. Everyday practice in schools and universities fosters the scientific environmental knowledge that is central to the orientations of climate activists. By contrast, the (...) practice of construction workers inculcates an embodied environmental knowledge which accompanies an orientation that takes environmental problems as not primarily a question of conservation, but rather as inherently linked to workplace matters. By way of conclusion, the article argues for an expanded notion of environmental concerns, beyond the acceptance of scientific facts on ecological crisis and towards embracing the embodied environmental knowledge more broadly prevalent among manual workers.
