Abstract
<jats:p><p style="text-align: justify;"><strong>Context and relevance.</strong> This study examines the interactions between self-organizational competence, work-related experiences, and fatigue as an unfavorable mental state associated with work performance. The theoretical basis for the study is an understanding of self-organization within the framework of activity theory, the substantiation of fatigue as an unfavorable mental state, and flow theory. <strong>Objective</strong>: to study the interactions between self-organizational competence, fatigue, and optimal work-related experiences. <strong>Hypothesis.</strong> Systemic resource formations that perform a regulatory function in a teacher's professional activity include competence-based, psychoenergetic, and emotional components. <strong>Methods and materials.</strong> The study involved 120 teachers from higher education institutions of the Ministry of Internal Affairs of Russia. Self-assessment diagnostic methods were used to identify the severity of self-organizational competence, indicators of work-related experiences, and a subjective assessment of fatigue. <strong>Results.</strong> Linear regression analysis yielded four models that met all acceptability requirements. The models reflect a developed system of relationships in which pleasure is the central link, self-organization is the basic regulatory resource, meaning is a secondary, derivative component, and subjective fatigue assessment acts as a psychoenergetic indicator of stress, reducing the severity of the other indicators. <strong>Conclusions.</strong> It was revealed that work enjoyment is the key resource associated with fatigue reduction. Self-organizational competence primarily serves as a resource and support function. The meaningfulness of professional activity is largely derivative and is formed on the basis of a positive emotional-evaluative attitude toward work.</p></jats:p>
