Building sustainable careers: The predictive effect of psychological capital and moderating effect of social support

Despite the growing body of research on sustainable careers, few studies have examined the predictive role of individual elements. Drawing on conservation of resources theory, we examined how and when psychological capital promotes employees’ sustainable careers. Using data from a two-wave survey and archived data, we tested our model with a sample of 580 employees. The results showed that (a) psychological capital was a positive predictor of employees’ sustainable careers, (b) perceived workload mediated the relationship between psychological capital and sustainable careers, and (c) social support amplified the indirect impact of psychological capital on sustainable careers via perceived workload. Implications of the findings are discussed.
