This chapter focuses on features of collaborative-dialogical work (C-D) in the context of building sustainable and more resilient social movements, more particularly the climate justice movement (CJM) in the Czech Republic. It suggests that C-D principles overlap with principles of the climate justice movement, especially the principle of prefiguration, and that C-D practice and CJM can inform each other. The chapter describes a broader context of the CJM in order to link it to specific issues and dilemmas concerning the sustainability and resilience of activist collectives within the movement. It discusses how attunement to moments of solidarity with climate justice helps us when working within the social change context and with developing specific relational sensitivity that enriches our professional and human engagement in various other settings.
