Mastery-avoidance (MAv) goals are recognized to be detrimental as they arouse counterproductive work-related behaviors. In the current literature, MAv goals are assumed to be more predominant among newcomers and longer-tenured employees. The alleged relationship provides important implications but yet has received scant empirical attention. In response, this study examines the proposed U-shaped curvilinear relationship between organizational tenure and MAv goal orientation. In addition, the potential moderating role of psychological empowerment on this curvilinear relationship is investigated. Based on data from 655 certified accountants, the results support the existence of the hypothesized curvilinear relationship. Also, it revealed that for employees who experience higher levels of psychological empowerment, the U-shaped relationship between organizational tenure and MAv goal orientation becomes flattened. Implications and future research are discussed.
