Abstract
The rapid advancement in information and communication technologies (ICT) has improved workplace productivity but also introduced new psychosocial stressors. Workplace telepressure, the urge to respond quickly to work-related messages sent via digital communication tools, often erodes employees' psychological well-being and blurs work-life boundaries. This study, grounded in the Job Demands-Resources (JD-R) model, investigates the influence mechanism between workplace telepressure and job burnout. Using data collected from 323 middle school teachers in China, results revealed that workplace telepressure significantly predicted job burnout. In addition, work-related rumination partially mediated this relationship, indicating a cognitive mechanism linking telepressure and burnout. Furthermore, perceived organizational support moderated the relationship between work-related rumination and job burnout. Specifically, when perceived support was high, the impact of rumination on burnout was weakened. These findings provide theoretical insights and practical implications for fostering healthy work environments and promoting psychological well-being in the digital era.
