Organizational toxicity, perceived support, and teachers’ work success, quality of life in Thailand

Purpose – This study aims to examine the structural relationships among organizational toxic work environment (OTWE), perceived organizational support (POS), quality of life (QOL), and work success (WS) among teachers in Thailand. Grounded in the Job Demands–Resources (JD-R) model and Conservation of Resources (COR) theory, the study tests the mediating role of QOL in linking organizational conditions to work success. Design/methodology/approach – A cross-sectional survey was conducted with 450 primary and secondary school teachers selected through multistage sampling across five regions of Thailand. Data were collected using validated questionnaires and analyzed using confirmatory factor analysis and structural equation modeling with bootstrapping (5,000 resamples) to examine direct and indirect effects. Findings – Organizational toxic work environment was negatively associated with QOL and WS, whereas perceived organizational support showed significant positive associations with both outcomes. QOL emerged as the strongest predictor of work success and partially mediated the effects of organizational toxicity and perceived support. The structural model demonstrated good fit indices. Practical implications – Educational administrators should reduce workplace toxicity and strengthen supportive organizational practices to enhance teachers’ quality of life and sustainable work performance. Originality/value – This study provides an integrated national-level model linking organizational toxicity, perceived support, QOL and work success, extending health organization management literature within an educational context in a developing country.
