This study explored (1) by what factors the employment of retired worker were prescribed, (2) what changes in working conditions they faced at the job after their retirement, (3) which types of retirement they regarded as desirable for themselves. Based-on these facts, how the rate of employment of retired workers, which has shown a tendency to decrease in recent years, would be raised was also examined. Questionnaire data were obtained from 754 male aged people who had retired from the firms in Aichi prefecture 5 years ago. Results indicated that those workers who had highly specialized skills and/or widely applied skills were more likely to be hired, and could engage in full-time work. It was pointed out from these findings that in order to increase the employment of retired people it was of importance (1) to employ flexible working hours systems, under which people wishing part-time work could be hired and (2) to develop career and training programs long before retirement to heighten their skill level and variety. Other results were discussed in terms of promoting elder workers' employment.
