Addressing Teacher Occupational Health in Challenging Times: The Role of a Positive Organizational Climate in Buffering Teachers’ Burnout

Teacher occupational health is a critical issue worldwide that COVID-19 has worsened. While previous research has highlighted the impact of chronic work-related stress and limited personal resources on burnout, much of this research relies on cross-sectional data that do not capture how these effects develop over time. Additionally, the role of positive organizational factors remains underexplored. Our study examined burnout trajectories among 101 Portuguese elementary teachers (94.1% women, M = 46.03 years, 85.6% enrollment rate) over five data collection points spanning the 1st and 2nd COVID-19 waves (2019–2021) and investigated the impact of organizational climate on teacher burnout. Main work-related stressors were identified through an open-ended question. Trajectories of burnout indicators were analyzed using independent ANOVAs, and moderation analyses tested the relationship between organizational climate, occupational stress, and burnout. Results showed a significant drop in perceived personal accomplishment during the first lockdown. Key stressors included greater job demands and more strained interpersonal relationships. Organizational climate significantly moderated the effect of work-related stress on overall burnout and emotional exhaustion and positively predicted personal accomplishment. This research contributes to a strengthened theoretical understanding of burnout as a dynamic, context-sensitive process, offering new empirical evidence, especially in underrepresented educational systems like Portugal. It emphasizes the importance of ad-dressing contextual factors when working to reduce teacher burnout. Rethinking professional development and workplace relationships is essential for supporting teachers’ occupational health in today’s uncertain educational environments.
