We present a systematic review of 54 empirical studies that examine the links between age-based perceptions/bias and career-related outcomes. Drawing on social cognitive theory, we conduct a systematic and interdisciplinary review that outlines the direct and indirect links between (a) positive and negative stereotypes and age discrimination and (b) individual and organisational career outcomes and acknowledges the contextual factors that influence this process. Our findings suggest that negative age-related stereotypes can directly or indirectly lead to discriminatory opportunity provision and employment practices, loss of enthusiasm for career planning, detriment to health, negative performance, and an unfriendly working climate through three pathways from the employee's perspective. Also, positive age-related stereotypes are positively associated with self-efficacy and can lead to equity in employment practices, passion for career development, and a friendly work climate. Our review provides insights for future research on age discrimination in the workplace and has practical implications for managers and policymakers.
