Within the Implementation plan of activities for economic recovery, on 6 May 2010, the Croatian Government decided to establish the Register of public sector employees (hereinafter: the Register). The task to establish the information system of the Register has been entrusted to the Croatian Financial Agency - FINA, and the detailed specification on the Register contents and functionality was prepared by the Ministry of Public Administration in cooperation with the Ministry of Finance and the Central State Office for e-Croatia. The Register is a collection of data on public sector employees, which is kept in an electronic form for the purpose of establishing the efficient system of centralized calculation of wages and human resources management. This paper presents in details the access rights and users rights to work in the Register application. It also describes the set of data contained in the application in relation to the institution and its employees, the way to manage files and to create reports based on the data entered in the Register. Central calculation of employees’ wages also uses data entered in the Register. Furthermore, this paper emphasizes the importance of establishing the Register and explains its benefits, which the state as an employer uses to easily and effectively manage its human resources. The overall aim of the Register is to increase the efficiency in public sector as a service of all citizens and to establish an effective system of wages calculation.
