More than 90 surveys conducted during the past 40 years covering a variety of disabling conditions and employers' concerns regarding workers with these conditions were reviewed. The goal of this review is to identify, develop, test, and disseminate interventions for rehabilitation practitioners to use in job development and placement. The review focused on employer perspectives on resources to facilitate the employment of workers with disabilities (referral and recruitment, accommodation, and staff training resources), the influence of federal contracts and labor unions, career initiation and establishment, career maintenance and advancement, and employer characteristics. It culminated in a series of recommendations for action on the part of rehabilitation practitioners, policymakers, and workers with disabilities. The review revealed that employers are much like the general population in that they have had and continue to have reservations about workers with disabilities despite the available evidence that disabled individuals make valuable, competent employees. Although employers do appear to be aware of the differences in persons with varying disabilities and do seem, to some extent, to assess different employees' abilities differently, it appears that stereotypes persist. This seemed especially true in the case of severe physical disabilities, mental illness, and mental retardation. It appeared that there are few hard and fast rules that can readily be applied to job development and the job placement of persons with disabilities.
