The predominant type of activity of a modern person is professional, which contributes not only to receiving financial reward, but also personal development, leaving an imprint on all levels of the individual's functioning: from value-semantic to behavioral. However, not only does the activity have an impact on the personality, but the personality as a whole has an effect on the activity that is being carried out – a mutually encouraging aspect. One of the significant factors affecting the personality is the extreme conditions for the performance of professional activities, which are associated with high psychoemotional loads and active intellectual activity. The profession of an air traffic controller belongs to this kind of extreme professional activity. Thus, the aim of the work was to study the prevailing type of subjective control in air traffic controllers with varying degrees of self-efficacy. The study was conducted in two stages, with the use of two questionnaires. At the first stage of the research work, it was revealed that 46.7% of air traffic controllers had an average level of self-efficacy, 40% of air traffic controllers had a low level of self-efficacy and 13% of respondents demonstrated a high level of self-efficacy. The next stage was the determination of the pole of subjective control in persons with different degrees of self-efficacy. Compared to individuals with low levels of subjective sense of personal effectiveness, air traffic controllers with high and medium levels of self-efficacy are characterized by intervality in achievements and positive attitude towards failures. Regardless of the level of self-efficacy, the respondents are dominated by the external locus of control in the field of labour relations. Thus, air traffic controllers with high and medium levels of self-efficacy tend to take responsibility in cases of success and failure. In turn, air traffic controllers with a low level of self-efficacy tend to blame themselves for failures and mishaps, consider themselves from the position of a source of possible troubles.
