Originally published in 1987, this book focusses on the debate around the international role of the working class and other dominated classes such as the rural and urban poor. The contributions discuss whether Marx's original version of the revolutionary role of workers can still be sustained. They examine the response of workers to the globalisation of production, to structural unemployment in the industrialized world and to the changing composition of the workforce in the industrialising periphery. The volume questions the historic starting points in the theorization of international labour.
