An organization is a group of individuals who have a common goal. Each employee has a specific set of work tasks and a supervisor. The relationship that develops between the leader and the employee greatly affects the perfomance quality of work tasks, but also the perception of the justice climate in the organization. If the relationships are poorly developed, the justice climate in the organization is disturbed, which leads to poor business performance. Lack of fairness prevents employees from identifying with the organization and leads to lower productivity. Only a person who is committed to the organization will give his maximum in order to achieve the given goals. In accordance with the above, this thesis deals with the connection between leader – member exchange and the justice climate. In order to build a quality justice climate, it is necessary for superiors to develop good relationships with subordinates and to be able to adapt to any situation, that is, to each individual. It should be emphasized that the excessive differentiation of the relationship between superiors and subordinates has harmful effects on the justice climate. There are a large number of factors that should be taken into account when building a relationship between a leader and employees and a justice climate, and they are listed in the rest of the thesis.
