Policies for retired employees have emerged as a hot issue for governmental bodies, employers, and financial organizations. Retired lecturers at public university intend to move to private ones to continue working. This research was conducted to identify psychosocial factors of lecturers’ attitudes to working after the retirement age. To address this problem, this study surveyed academic staff in Vietnamese universities followed by the statistical analysis of factors affecting lecturers’ attitudes. The findings from the study showed that five out of six hypotheses were accepted. The results can be used as a reference for university managers so that they could establish a deliberate policy on the retirement issues. This study has contributed to the decision-making process related to human resources management policies to improve the quality of education, promote a healthy development and then achieve sustainable competitive advantages.
