| Abstract: | In this article, the pattern of occupational segregation by sex in the UK between 1979 and 1989 is explored through the decomposition of the new Karmel Maclachlan index. Over the upturn, 1983–89, integration of the sexes, as measured by the Composition Effect occurred faster for full-time employment than total (full-time and part-time) employment. On the other hand, integration, in general, proceeded more slowly over the downturn of 1979–83 but total employment showed a more rapid rate of desegregation than full-time employment. Further analysis of the index, based on notional redistributions of part-time and full-time employment, confirms that part-time employment appears to be disproportionately responsible for the overall level of occupational sex segregation and to inhibit its decline over the upswing. These results are attributed to the different labour supply behaviour of males and females and the propensity of employers to treat part-time employees as a flexible reserve. Policies are outlined to counteract both the unequal treatment of part-time workers, particularly women, and the allocative inefficiency caused by the growth of part-time employment, relative to full-time employment. |
