Abstract
In recent years, plenty of attention has been paid to emotional intelligence as the ability to understand the meaning of emotions and use this knowledge to find out the causes of problems and solve these problems. The main components of emotional intelligence are found in the classification of professionally important qualities of teachers: emotional restraint, emotional balance, empathy, communication, and managerial abilities, including the ability to manage their own emotions in the process of communication. The inability to understand one's own emotions and the emotions of other people, to correctly assess the reactions of others, as well as the inability to regulate one's own emotions in moment of making decisions, lead to many life failures. Thus, teachers, since they are constantly in interaction with their students, need to develop this skill as one of the most important in preparing for leadership. This study is aimed at studying the emotional intelligence of modern teachers, we also looked at the effect of the level of emotional intelligence on their self-esteem. The study involved 100 teachers aged 24 to 50 years. The following methods were used: the questionnaire of emotional intelligence by D. V. Lyusin, the method for self-assessment Dembo-Rubinstein. The results of this study confirmed the hypothesis that there is a link between emotional intelligence and the self-esteem of schoolteachers.
