Supervisor credibility was used to predict employee well-being indices in two separate studies (total N = 675). In Study 1, perceptions of supervisor credibility (competence, goodwill, and trustworthiness) were all positively related to job satisfaction, motivation, and organizational commitment. Regression analyses indicated that goodwill was the strongest predictor of all three employee well-being outcomes. In Study 2, all three dimensions of supervisor credibility were positively related to empowerment and personal accomplishment, and negatively related to burnout. Regression analyses indicated that goodwill was the strongest predictor of empowerment and both dimensions of burnout, whereas competence was the best predictor of accomplishment.
