"Many governments, large institutions, and collective actors rely on the principle of solidarity to embed social policies on firm normative and legal grounds. In this original volume, a multidisciplinary roster of scholars come together to examine the contributions - and challenges - implicit in relying on the idea of solidarity to "inscribe" this principle in social policies. Chapters explore how the dependence on the solidarity principle, and especially on inclusive understandings of solidarity, can strengthen or weaken institutions and movements. The volume's contributors cover developments across decades with a multilevel approach exploring dynamic interactions between local, national, and supranational arenas in pursuing and adjudicating the solidarity principle. Unique and innovative, Inscribing Solidarity examines the implications and dynamics of solidarity across a variety of terrains to illuminate its concrete limitations and specific advantages.
