The purpose of the study is to explore the social workers' understanding and value of their intention to stay at nonprofit Christian organizations, and the transformation in their attitude toward organizational retention after facing the retention and turnover situation. A phenomenological qualitative approach was adapted to conduct in-depth interview with 10 social workers at nonprofit Christian organizations. By investigating their work experience of intention to stay and their perception of the transition from retention to turnover, the findings of the study were as follows: 1. Work-related reasons for social workers' intention to stay include: sound human resource management and workplace spirituality, servant leadership of managers, and decision-making participatory management of leader style. 2. Personnel-related reasons for social workers' intention to stay include: psychological, emotional and moral links with the organization, occupational commitment, and achievement of ability value and individual value. 3. The characteristics of nonprofit Christian organizations have driven the social workers' potential and positive response, satisfied social workers' spiritual and mental state, and in turn made them intent to serve on organizational effectiveness. Accordingly, some recommendations for ‘intention to stay' and human resource management were provided, and implications for strategic management, manager execution and social workers' career planning at nonprofit Christian organizations were sent.
