This exploratory study investigates whether there is a relationship between young managers' interpersonal stress and various management development practices. In recent years, practitioners and researchers have focused on stress studies and related practices in the workplace. However, stress encountered by young managers has received less attention. We examine possible sources of young managers' interpersonal stress and develop a scale through exploratory factor analysis. Participants are less than 35 years old, mainly from the financial, high-tech and service industries in Taiwan. Organizational managerial development practices are discussed to understand their relevance to young managers' interpersonal stress. The results suggest that the more opportunities young managers have to make decisions, the more their opinions will differ from those of their middle-aged fellow managers and senior subordinates. However, organizations with formal assessment may lessen disagreements with middle-aged fellow managers. Future studies regarding young managers' interpersonal stress can be carried out using this scale and can explore whether other, specific organizational management development practices are related to lower stress levels among young managers.
