This chapter explores the concept of the dual labour market that has gained widespread currency in British Sociology as central to the analysis of the employment positions of certain groups of workers, particularly women and black people. It focuses on a second important discussion of dual labour market theory in the British context by Barron and Norris entitled 'Sexual Divisions and the Dual Labour Market'. The chapter assesses whether dual labour market theory can adequately account for the structure of a particular industry, woollen and worsted. It describes about the limited objective: utilising data from the woollen and worsted industry, they have shown the difficulties of imposing a simple dualistic structure on the results. The chapter discusses an analysis of the woollen and worsted industry, they have tried to show the fundamental weaknesses of the theory and the necessity of moving towards a more concrete analysis of the capital-labour relation.
