This case study from my research project on Other People’s Struggles concerns solidarity in the global justice movement, and especially the alter-globalisation movement. The wider project concerns how ‘outsiders’ in a social movement – those who are not motivated by standing to benefit if the movement achieves its goal – participate. How do they achieve solidarity with those who do stand to benefit? The Global Justice Movement is an interesting case because the beneficiaries and the campaigners are quite widely separated. Many of those who campaign for global justice are not themselves made insecure by globalisation (sometimes quite the reverse, in fact). And yet their senses of solidarity with the global poor are deeply felt and important to them. Does this solidarity consist in shared perspectives, or ‘framings’ of global justice? Or does the struggle itself provide the solidarity?
