Globalization is transforming the spatial organization of the world economy. In particular, it is leading to the “shrinking globe” phenomenon and the speeding up of social interaction between places across the planet. Given that international labor solidarity is a process of coming together across space, I argue that the spatial reorganization of global capitalism has important consequences for practices of solidarity. Specifically, I suggest that the spatial context within which they find themselves is likely to impact the types of political praxis in which workers engage. Thus, whereas globalization may encourage some workers to engage in traditional international solidarity campaigns it might also, paradoxically, lead others to focus on highly local campaigns, the consequences of which can quickly be spread far and wide as a result of the growing spatial interconnectivity of the planet that globalization has augured. Likewise, the spatial context within which they find themselves may lead some workers to defend their class interests while others defend their spatial interests. Equally, while some unions are focusing upon organizing what I call the spaces of production, others are organizing around the spaces of consumption. Given that workers’ spatial context impacts their spatial goals and political praxis, I argue that it is important to conceptualize international labor solidarity in explicitly spatial terms if we are to understand why different groups of workers may pursue radically different types of political praxis in different places and at different times.
