The article is devoted to the study of the dominant strategies of conflict behaviour and communicative tolerance of cadets and students of the educational organisation of the Ministry of Internal Affairs of Russia. The results of an empirical study conducted on a sample of 7770 cadets and trainees are considered. It is shown that communicative tolerance determines strategies of conflict behaviour and has an impact on staff turnover. It was revealed that cadets and students of the Moscow University of the Ministry of Internal Affairs of Russia named after V.Ya. Kikot’ demonstrate a high level of communicative tolerance, which is manifested in their attitude to various social groups, acceptance of the individual characteristics of colleagues, faculty, management. The structure of conflict behaviour strategies defines the presence of indicators of ‟avoidance and self-blame” (the direction of reaction to oneself, with the acceptance of guilt or responsibility for correcting the situation that has arisen, and it is not subject to condemnation) and ‟aggressiveness and conflict.” The conducted research confirmed the need to continue working on the formation of conflict-free behaviour and communicative tolerance of cadets and trainees in the system of staff turnover prevention and the creation of a number of psychological and pedagogic conditions. Scientific and practical recommendations on the formation of conflict-free behaviour and communicative tolerance of cadets and trainees in the system of staff turnover prevention are proposed.
