This study examines the mediating role of job fit on the relationship between perceived supervisor support (PSS) and perceived organizational support (POS), and the mediating role of personal sacrifice on the relationship between POS and turnover intention. We use structural equation modeling (SEM) with a data set consisting of a sample of 346 individuals in a manufacturing firm to test our proposed model of PSS, POS, and turnover intention. Consistent with prior literature, our hypothesized model confirms that PSS is a predictor of POS and that POS is a predictor of turnover intention. By testing two additional competing and theoretically derived nested models, our findings indicate that job fit partially mediates the relationship between PSS and POS, and that personal sacrifice partially mediates the relationship between POS and turnover intention. Our study is among the first to examine job fit and personal sacrifice as mediators within the POS-turnover intention model.
