This paper aims to advance knowledge about corporate environmentalism by using new concepts and methods. We broaden the concept of the firm as "differentiated composite actor" by including not only managers but workers and unionists as actors. We descend into the "hidden abode of production" using Lefebvre’s concept of "everyday life" to explore the barriers environmental policies experience in this sphere. We base our explorations on life-history interviews to understand how the imaginaries of production are embedded in people's self-conceptions. We identify seven barriers to the implementation of environmental practices: deficient regulations, collusion between controller and controlled, de-prioritisation, hierarchism, compartmentalisation, specialisation, and social unsustainability. A "necessity discourse," legitimating the priority of efficiency and product quality over environmental sustainability, subjugates alternative sustainable practices. The paper concludes with a discussion of the results in the light of previous investigations, suggesting that the concept of the everyday could enrich future research.
