Investigating the Dual Moderated Mediation of Work Autonomy and Supervisor Support in the Relationship Between Workload and Turnover Intentions Through Burnout

Drawing on Job Demand-Resources theory and Conservation of Resources theory, this study empirically investigates the mediation of burnout on the relationship between workload and turnover intentions and the first-stage dual moderated mediation of two important job resources of work autonomy and supervisor support on a convenience sample of 169 working adults working from home during the COVID-19 pandemic crisis in Singapore. Results significantly support the hypothesised positive indirect effect. Only work autonomy significantly strengthens the indirect effect only when work autonomy is high in contrast to the conditional indirect effects hypothesis. Simple slopes analysis suggests that work autonomy buffers the health-impairment process only at lower levels of workload.
