White-Collar Proletariat (1980) explores the major changes in the industrial and political behaviour of British civil servants in the 1970s. It looks at their turn to militancy  and asks whether it can be explained by reference to the sociological concept of proletarianization, a concept defined with particular reference to Marx and neo-Marxist writers. Attention is focused on a number of variables which sociologists have regarded as critical, those of level and source of income, social origins and the organization of work.
