The democratic principle of political co-determination requires, for its realization, workplace processes that are often left out of political discussions. The supposition that workplace dynamics are separate from the political realm of democratic governance has led to blind spots regarding the close relation between the two, and how the former deeply shapes the latter. Workplace dignity and co-determination provide the psychological and social foundations for an active citizenry, and workplaces can act as a microcosm for broader democratic process. The current essay describes the social philosophies linking work to democracy and explains how this crucial link to democratic theorizing was subsequently lost. Describing five ways in which workplaces can, in principle, undermine chances for democratic co-determination, the essay then examines the normative conditions for work that would be needed to regenerate the basis for democratic participation. A business ethics that claims to support democracy must therefore seriously consider the nature of workplace injustices, not only as personal injury, but also as affronts to social and political participation.
