The task of promotion is one of the most important elements of the business life for employees working in public administration and public organizations. Just as in the private sector, public sector employees also want to be promoted in their duties, to have authority and powery, and thus to increase their wages. There are regulations of promotion in the public sector also to meet both these expectations of its employees and to meet the needs for managers in line with the needs of the sector. In other words, the task of promotion is shaped around a system that is prescribed by these legislation. What justice perception which this system has formed in the eye of employees is like has a great importance for the sector and its employees.
