This book reports the findings of a national survey of corporate practice and thinking relating to the better use of our aging work force. The study was directed by Elizabeth L. Breckinridge under the supervision of the Committee on Human Development at the University of Chicago and was financed by a grant from the Rockefeller Foundation. The purpose of the survey was "to explore (1) the way in which some companies were using older workers more effectively than the average employer and (2) the procedures being devised to facilitate retirement and subsequent adjustment." Ninety companies, ranging from great corporations like General Motors and Standard Oil down to small shop operations, cooperated in supplying the information contained in this book. The author has arranged her material into a clear and pleasant narrative dealing successively with hiring, retiring, placement, counseling, maintenance of health and morale, preparation for retirement, and postretirement programs.
