The role of nonworkplace and workplace social support in mitigating burnout's impact on job satisfaction and turnover intention among vietnamese manufacturing workers: A conditional mediation model

This study examines how nonworkplace and workplace social support moderate the mediation process of job satisfaction between burnout and turnover intention in manufacturing workers. Relied on a sample of 349 Vietnamese manufacturing workers, we tested the conditional mediation model using ordinary least squares estimation, with job satisfaction as the mediator. Nonworkplace and workplace (coworker and supervisor) support were regarded as moderators in the associations between burnout, job satisfaction, and turnover intention. The results revealed that job satisfaction significantly mediates the relationship between burnout and turnover intention (indirect effect = 0.095, 95% CI = [0.051, 0.166]). Among the workplace social support factors, coworker support buffered burnout’s negative impact on job satisfaction (interaction effect = 0.217, p < .05), while supervisor support weakened its positive link with turnover intention (interaction effect = -0.133, p < .05). Conditional mediation analysis further demonstrated that burnout’s indirect effect on turnover intention through job satisfaction depended on coworker support, with the effect being significant when coworker support is low (indirect effect = 0.12, 95% CI = [0.04, 0.20]) but nonsignificant when coworker support is high (indirect effect = 0.04, 95% CI = [-0.04, 0.17]). However, nonworkplace social support did not moderate these relationships (p > .05), suggesting that workplace-related support plays a more critical role in shaping job attitudes and turnover decisions. Additionally, when all sources of social support were high, the mediating role of job satisfaction in the burnout-turnover intention link remained significant (indirect effect = 0.09, 95% CI = [0.02, 0.17]), indicating that extensive social support does not fully counteract the negative impact of burnout. These findings emphasize the importance of workplace social support in alleviating burnout's adverse effects, offering valuable intervention strategies to enhance employee well-being and decrease turnover in the manufacturing sector.
