--- - |2 In this article, we examine the potential of global union pedagogy to address the structural and political challenges of cross‐border trade‐union action. We do so by proposing an analytical framework that draws on labour relations, political sociology and education to explain educational processes and outcomes as responses to the pitfalls of global labour campaigns and the inadequacy of global and local labour institutions. We proceed to assess the value of our framework by elaborating on its different dimensions – framing, synthesizing, connecting and regenerating – in relation to the educational work of a global union federation, namely the International Transport Workers' Federation. We find that an actor‐centred approach that combines top–down, bottom–up as and horizontal processes of collecting knowledge from different contexts and making links between different countries, industries and parts of supply chains can help actors realize that their seemingly diverse concerns are essentially different manifestations of the same problem. - 'Global Networks, EarlyView.
