This research investigated how and under what conditions thriving at work affects career attitudes and behaviors. Using an experimental design (n = 174), Study 1 found that the effects of thriving on career satisfaction, career commitment, and career engagement were mediated by career resilience. The positive effect of thriving on career resilience and the resilience‐mediated effects of thriving on career satisfaction, commitment, and engagement were stronger when achievement orientation was higher. Study 2 verified these findings with a survey of another sample of 296 employees. These studies offer important insights for human resource managers and career consultants or practitioners regarding what may enhance employees' career outcomes. Our findings imply that thriving‐enabling practices might be beneficial among highly achievement‐oriented employees.
