Organizational values determine the behaviour and norms expected in the organization. The more similar the attitude, the way of thinking and the value system among organizational members the stronger the culture is. The characteristics of personality can be well modelled with the concept of self-evaluation. The purpose of this article is to create a theoretical framework that reveals the relationships between self-evaluation dimensions, organizational values and employees’ commitment dimensions. Based on the results, affective commitment is supported by a high level of self-esteem and self-efficacy through the organizational values such as collaboration, trust, affiliation, achievement, autonomy, competition and growth. In contrast, professional commitment is supported by a high level of locus of control and emotional stability, through the organizational values such as routinization, attention to details, formalization, support, communication and consistency. The conclusions of the theoretical model can be used to determine effective motivational strategies for groups and organizations with strong cultures, as the results show that motivational tools used at group level can be successful as well, depending on the self-evaluation profiles.
