 However, collective life, in addition to having advantages, is also endowed with negative features. Indicators of collective distress that have a direct impact on the professional burnout of an individual member of the team are identified. These include problems and / or lack of corporate culture; dissatisfaction with the psychological atmosphere prevailing in the team; presence of conflict situations, quarrels, intrigue; absence or problems of interpersonal communication in the team, division into groups; low level of mutual assistance and support, unwillingness to maintain friendly relations; no punishment for guilt, reaction to negative behavior of colleagues, control over subjective factors; lack of prospects for team development; lack of conditions for personal development and formation; lack of measures to prevent occupational burnout.
