The crisis of reproductive work is a central point in feminist analysis of the multiple crisis. In Germany, a 'social contract for sustainability' is proposed as a solution to the ecological crisis, and especially that relating to climate change. Hence the reaction to the multiple crisis is to construct a social contract. This is the starting point of our argument which sees the social contract as part of the crisis but, if re-cast, as potentially part of a sustainable solution. The chapter refers Val Plumwood's critique of the separated self which is part of all classical conceptions of social contract. It proposes a relational account of the human being as a foundation for a new social contract for sustainability. The experiences of every woman and man in all spheres of work are necessary for the further development of the reproductive process. This also means to surrender the model of the human being as manlike, as egoistic and autonomous.
