ABSTRACT
In 1911 about 10% of the British work force held the sorts of occupations that indicate membership of the service class. In 1991 about 30% of the employed held nominally equivalent managerial or professional positions. The history of employment during the twentieth century is partly the tale of a shift from an economy where the vast majority of employees are directly engaged in the physical manipulation, transformation and transportation of things to one where a substantial number are engaged in the management, organization and dissemination of people, paper and ideas.
