The paper presents the results of research on the feelings of professional burnout in teachers of secondary schools. In its first part, a professional burnout model is presented, as well as symptoms and consequences of the burnout process. Then, main sources of burnout, common prevention strategies, and main areas where signs of burnout can occur are discussed. An important part of the paper is formed by the analysis of the results of a survey conducted among 315 teachers in the Lublin and Starachowice districts. It is worrying that, according to the research, every fifth teacher is characterised by very high or high level of the professional burnout feeling. Therefore, the necessity to prepare future teachers – already at the stage of their education – to cope with unusual educational situations and apply strategies preventing professional burnout, turns out to be of particular signifi cance. These issues are reflected on in the conclusions and recommendations for teachers, included in this paper.
