Teacher wellbeing has a significant impact on student learning. Teachers report the highest levels of occupational stress compared to other professions. Sources of teacher stress include excessive workload, student behavior issues, lack of support, and workplace bullying. Early career teachers are especially vulnerable. Consequences of teacher stress include poor engagement, attrition, burnout and poor student outcomes. Reducing stress requires supportive school cultures with policies addressing workload, behavior, training and wellbeing strategies. Individual coping strategies like exercise and direct problem solving can also help reduce teacher stress.
