When schools closed due to the COVID-19 pandemic in March 2020, teachers suddenly had to teach remotely. To better understand the possible impact of these measures on teachers' work functioning and well-being, this study examined teachers’ needs. Using a thematic analysis approach analyzing the 1,115 open-ended answers, three domains related to needs were identified: work-life balance and working from home, teaching and interaction with students and parents, and school management and colleagues. Findings are interpreted from existing frameworks (i.e., Jobs Demands-Resources (JD-R) model and Self-Determination Theory (SDT)). We also identified several unique needs, such as adjusting learning goals.
