In contrast to the expected tasks and responsibilities, the informal role is an interpersonal behavior model that a team expects from a team member on the basis of the impressions they create while working together. In other words, informal roles are roles that form themselves as a result of the relationships of the members of the organization. The general purpose of this study is to study the informal role patterns that influence the efficiency and effectiveness of organizations according to the work done in literature. In this context, it is to investigate the informal roles that individuals who continue to exist within the socio-cultural structure, in addition to their formal role behaviors, take over. This study has been discussed in the framework of four questions. These questions, respectively, "What do the concepts of formality and informality mean in management?"What are the approaches related to the concept of informality?“What is the concept of informal role?“What forms of informal role appear between the employees in the organizational life or between groups and what effect does it have on the organization?” The study found that informal roles have some advantages and disadvantages in terms of organizations. Therefore, it is especially necessary that all employees, together with the organizational managers, realize the informal roles that support formal roles or undermines.
