This report reviews the knowledge gained in 4 years of operation of labor mobility demonstration projects and provides guidelines on the design and operation of a permanent worker relocation program. Data were gathered both from written material covering the experience of each project and from field trips to some of the projects when additional data were needed for interpretative purposes. Measured in terms of program costs, training, relocation, and financial assistance, the labor mobility projects demonstrated that worker relocation can be used efficiently to assist unemployed people of various backgrounds and skill levels to find employment. As a possible method to alleviate structural unemployment caused by changes in the location and composition of economic activity, worker relocation can be an important part of a comprehensive national program for manpower development and utilization.
