The present study answers the call for more studies to investigate the age diversity climate's effect on individual-level outcomes. Building on the social identity approach and social exchange theory, we surveyed 110 Italian employees aged between 18 and 61 years old (M = 46.10, SD = 10.02) and investigated the role of age diversity climate in predicting intentions to quit (H1), job-related wellbeing (H2), and work engagement (H3). Our findings confirmed the hypotheses (H1 and H2), showing the added effect of age diversity climate over and above age, job tenure, role clarity, job demands, job control, perceived support, and perceived job and organizational fit. In fact, age diversity climate accounted for a significant increase in the variance explained for two of the three hypothesized models (i.e., intentions to quit and job-related wellbeing, but not work engagement). To conclude, this study contributes to the existing literature by showing the age diversity climate's predictive value for turnover intentions and job-related wellbeing, and corroborating the importance of supporting age diversity through a variety of Human Resources Management strategies.
