Teachers' occupational stress is an important topic in educational research, with implications for their well-being and performance. This study analysed the relationship between grit, defined as passion and perseverance for long-term goals, and the perception of occupational stress among primary school teachers in Romania, in the context of school year reorganisation from 2 semesters to 5 modules. This exploratory cross-sectional study included a sample of 158 primary education teachers from the northwestern region of Romania. Work-related stress was assessed through a questionnaire adapted from "School Teachers Job Stressor Scale" (Naono-Nagatomo et al., 2019), and the grit level was measured using the scale developed by Duckworth (2016). The results revealed differentiated levels of occupational stress, the highest being associated with the reorganisation of the academic year. The correlation analysis indicated significant negative relationships between grit levels and certain stress dimensions, particularly self-assessment of professional skills and peer relations, while the relationship with the overall stress was not significant. The qualitative data supported these findings, suggesting that grit facilitates stress management in specific contexts without equally influencing all dimensions of work-related stress. These preliminary findings emphasise the multidimensional nature of occupational stress and highlight the need for future research with larger, more representative samples to replicate and extend these associations.
