This directory was prepared to foster the mutually supportive relationships among the Productivity and Quality of Working Life Centers in the United States. It was also designed to be of value to innovative managers in the public and private sectors by making readily available sources of information on the various aspects of productivity and quality of working life issues. The twenty-eight centers included in this directory vary widely in terms of development, scope, and sources of support. Several are essentially national or regional in approach; others generally confine their activities to their respective states; and some are university-based. Their financing comes from both public and private funds. All are involved in programs of interest nationwide. The following elements are found in the description of each center: address/phone number; background; organization; funding/support; program activities; and publications/A-V materials. Appended are a listing of foreign Productivity and Quality of Working Life Centers and a geographical index (by state) of U.S. Productivity and Quality of Working Life Centers. (A companion document, CE 019 154, contains the final report of the National Center for Productivity and Quality of Working Life, whose primary functions are to make the United States aware of the benefits of productivity growth and to encourage initiatives that will result in better productivity performances.)
