“Collective action in global supply chains refers to a coordinated, multi-stakeholder approach where various actors—such as governments, workers and trade unions, employers (national, transnational, and global), civil society organizations, multilateral institutions, and development agencies—work together to address complex challenges and achieve shared objectives within supply chains.” (ILO, 2021) The aim is to tackle systemic issues such as occupational safety and health, corruption, sustainability, and human rights, which are too complex for any single entity to resolve alone (ibid). They usually involve jointly set common goals, clear strategies and tools for implementation, information and resource sharing. An essential prerequisite for success is building trust among all actors involved.
