This study focused on the effects of subordinate-supervisor conscientiousness fit on organizational commitment and job satisfaction, and explored the mediator effect of trust in leadership between subordinate-supervisor conscientiousness fit and outcomes. The results showed that some specific dimensionalities of the subordinate-supervisor conscientiousness fit had significant positive influence to trust in leadership, organizational commitment, and career satisfaction. There are significant positive correlations between trust in leadership and organizational commitment, career satisfaction; and trust in leadership plays partial mediator role between independent variables and dependent variables. Implications of the results for theory and practice are discussed.
