The paper discusses the importance of organizational socialization as a process of gaining knowledge on the organizational success of employees' social adaptation and encouraging their social competence. Organizational socialization as a scientific discipline as well as practically oriented adjustment activity towards employees' working environment has developed methodology and tactics of socio-cognitive, behavioural and motivational encouragement of employees to the acceptance of organizational culture. It is assumed that in the process of organizational socialization, in addition to professional and organizational adaptation, the focus is on the development of employees' social competences. Although within the evaluated performance appraisal of social competence is only estimated, and also neglected in the overall assessment of employees' work performance, organizational climate for good social skills is of great importance due to the fact that enhanced social and interpersonal communication and interaction can increase operating synergies and contribute to better business results. Although social skills are an important element of human capital, they are still insufficiently recognized as a form of intangible resources that participate in the long-term value creation. The deficit in this area can lead to the problems in performance of human relations at the workplace.
