Major research findings are synthesized and innovations of current concern to vocational rehabilitation professionals are reported in this document, which covers the area of sheltered industrial employment. It is intended to provide a state-of-the-art review of worldwide experience and conceptualizations regarding accommodated or sheltered employment in both the segregated and mainstream worlds of work for workers with disabilities, and to provide an information base for future planning of implementation strategies for accommodated or sheltered mainstream projects in the public and private sectors in the United States. Topics covered in the introduction include the following: definitions, legal background, consumer views and demands, philosophical perspectives, wage versus welfare, and alternatives. Chapter 2 provides information on segregated employment opportunities, to the limited extent that they offer pure opportunities for employment rather than rehabilitation services. Chapter 3 provides information on worldwide experience with mainstream employment. Chapter 4 provides a brief sampling of information on American experience relating to the role of industry in preparing disabled people for work in mainstream settings. All chapters emphasize experience relevant to workers with disabilities so severe that accommodation or shelter is required for them to work. Chapter 5 presents considerations for the future and some ideas, conclusions, and suggestions for how the body of experience described might be used in planning future action. An annotated bibliography is included. (TA)
