The study aims to elicit a process model to enhance the understanding of the relationship between work passion and the fourth dimension of burnout i.e. organizational cynicism. It explains the mediating role of perceived sustainable leadership and psychological well-being in the process model. A survey of 232 employees working in diverse industries in India was conducted. Structural equation modeling was performed to test the anticipated process model of work passion. The findings reveal that the hypothesized relationship between work passion and turnover intention was supported. Sustainable leadership partially mediates between passion and cynicism and acts as an inhibitor toward cynicism. On the contrary, cynicism partially mediates between sustainable leadership and turnover intention and acts as a facilitator.
