Abstract
This article reviews theoretical and empirical work in labor economics and the sociology of work relating to the segmentation of the labor market into a primary and a secondary sector and examines the implications for vocational rehabilitation. Demand-side and supply-side factors associated with labor market segmentation and movement of workers from the secondary to the primary sector are reviewed. Transition into primary sector employment is explored as an important aspect of career development for individuals with disabilities. Recommendations for working toward this goal are offered for job development, job analysis, and job training and support.
