Teaching has been characterised as a stressful profession that is prone to burnout. Less is known about the specific ways in which teachers experience and navigate stressors associated with their work. This study aimed to qualitatively understand how teachers who perceive high and low levels of burnout characterise their lived experiences in school environments. Data were collected through interviews with 28 inservice teachers (11 male, 17 female) from the US Midwest who reported high- or low-burnout on a psychometric survey. Data were analysed by two experienced qualitative researchers. Results indicated that (a) low-burnout teachers perceived nurturing teaching environments, (b) high-burnout teachers perceived combative and constraining teaching environments, and (c) all teachers had to manage workplace stress. Building from these findings, we present a model for understanding how the school environment influences teacher burnout. This model highlights the importance of developing optimal working conditions that nurture teacher development.
