OCCUPATIONAL, INDUSTRIAL AND DISTRICT CHANGE IN THE POST-WAR YEARS
Most of the post-war occupational changes made by those interviewed were accompanied by a change of job; but the proportion of occupational changes made without a jobchange, 22 per cent in Battersea and 3 I per cent in Dagenham, was not negligible. Some types of occupational change were, indeed, more commonly made without a change of employer; for example, promotion to supervisory posts and upgrading from semi-skilled or labouring work to skilled work. Changes of these kinds formed between a quarter and a third of the occupational changes occurring without change of employer. Changes, particularly of the older men, from semi-skilled work and heavy labouring to light labouring also
occurred more frequently without than with a job-change, accounting for some 15 per cent (Battersea) and 10 per cent (Dagenham) of the occupational changes which did not involve a change of job. In both areas, however, over half the changes which were not accompanied by a change of job were very similar to those which occurred with a job-change; that is, they were between semi-skilled occupations of various kinds or from labouring to semi-skilled work.
