When Work Overload Cuts Both Ways: Job Crafting, Emotional Exhaustion, and the Role of Self-Efficacy in Rural Teachers' Subjective Well-Being.

Rural teachers often face work overload arising from demanding teaching responsibilities and extensive non-teaching duties, which may be closely associated with their subjective well-being. However, prior research has largely adopted a single-effect perspective, paying insufficient attention to the potentially competing mechanisms linking work overload to well-being. Drawing on cognitive appraisal theory of stress, this study develops a moderated parallel mediation model to examine the dual pathways through which work overload is associated with rural teachers' subjective well-being. Survey data were collected from 639 rural primary and secondary school teachers across 12 provincial-level regions in western China. The proposed model was tested using confirmatory factor analysis, hierarchical regression, and bootstrapping. The results indicate that work overload is positively associated with subjective well-being through job crafting, but negatively associated with subjective well-being through emotional exhaustion. Self-efficacy strengthens the positive association between work overload and job crafting while weakening the positive relationship between work overload and emotional exhaustion. Moreover, self-efficacy moderates both indirect associations, amplifying the beneficial pathway through job crafting and attenuating the detrimental pathway through emotional exhaustion. These findings reveal two distinct mechanisms linking work overload to rural teachers' subjective well-being and extend research on occupational stress by identifying self-efficacy as an important boundary condition. The study also provides practical implications for educational authorities seeking to optimize workload arrangements and develop targeted support and incentive mechanisms for rural teachers.
