‘Global worker’ designates collective labour that is : i) internationalized by the world-scale expansion of capital, a process in whose long historical arc a turning point is the doubling of the available global labour-power occasioned by the 1989 fall of the socialist states; ii) variegated by an increasingly complex division of labour, conventionally termed ‘the growth of the service sector’ (Soubbotina, 2000), describable in Marxist terms as an expansion of employment in the spheres of circulation and social reproduction; iii) universalized by the inclusion of women–aka ‘the feminization of work’ (Morini, 2007), the growth of production centers outside the global north-west, and flows of migrant labour, all shattering the notion of a white, male working class; iv) connected, albeit to very differing degrees and with many stratifications, to digitalized communications systems – crude but telling indicators are the global count of two billion Internet users and five billion cell phones; v) precarious in its conditions, with a chronic insecurity underpinned by capital’s access to a transcontinental reserve army of the unemployed, a surplus population whose task it is to survive in a state of readiness for work; iv) planet-changing in the effects of its labours, effects that, while historically cumulative, are only now becoming visible in global bio-crisis.
