Organizational justice theories are classified as Adams' equality theory, Deutsch's distribution theory, the justice judicial model developed by Leventhal, Crosby's relative deprivation model, Thibaut and Walker's self-interest model and the group value model. The theory of equality questions whether people have a moral state of the rewards they receive during their perceptions of justice. The concept of equity or equality that makes up the theory consists of distributive justice and mental incompatibility approaches. Observations have been made about the fairness of what employees will receive as a result of their contributions to organizations in the justice judicial model and it has been concluded that this will not be possible under all circumstances. It was argued that it would be fair to obtain the gains deservedly and to create appropriate environments for the needs of employees to be taken into consideration. Distribution theory is related to the distribution of conditions and achievements between individuals that can affect a person's physical, psychological, social and economic status. Decateration theory is related to the distribution of conditions and achievements between individuals. The theory of relative deprivation is a theory that describes a situation experienced by an individual who cannot benefit from equality. In this theory, it refers to the emotion that an individual feels when making contradictory and negative comparisons. According to the control model, individuals' thoughts about the fairness of decisions are a major determinant of the reactions they elicit against the gains they benefit from procedures. In the group value model, it is argued that group interests should take precedence over personal interests. Employees are expected to act together with the group and treat their cats fairly. In this model, individuals want to belong to a group and stay in long-term relationships with their groupmates. Key Words: Educational Institutions, Educational Administration, Organizational Justice
