The article discusses the problem of understanding the construct of “employee engagement in the organization” in scientific and practical literature. It is shown that the concept of “organizational commitment”, “organizational citizenship behavior”, “organizational identification” and “work engagement” are often seen as overlapping with the construct of “employee engagement in the organization”. There is also a variety of concepts describing the relationship of the employee with the organization, which creates terminological confusion and difficulties for their practical use. It is proposed to merge the concept of “identification”, “commitment to organization” and “work engagement” in a more general notion of “involvement of employees in the organization”. Briefly describe the results of two empirical studies that partly confirm the heuristic character of this approach.
