Establishing employment relationships in public services in the Republic of Croatia is subject to strict rules and procedures ensuring transparency and fairness in recruitment. This paper explores the pivotal role of public administration as a fundamental pillar of social organization and a vital factor in the functioning of state institutions in Croatia. Through an analysis of historical development, the study investigates how public administration has adapted to changes in political systems, evolving from monarchy to the contemporary democratic model. The structure of public administration encompasses state administration, local and regional self-government, and legal entities with public authority, each playing a crucial role in delivering services to citizens and coordinating regional interests. Special attention is given to the role of public services in meeting a wide range of citizen needs, financed through the state budget, local taxes, and EU funds. Regulation of employment relationships in the public sector ensures fair working conditions and transparent hiring processes, compliant with national and EU law. Through a case study of Vukovar-srijem county, the paper highlights the importance of transparency, fairness, and efficiency in the recruitment process within public services. By analyzing competitions, testing, and interviews, the study demonstrates how objective assessment of candidates' competencies is ensured, critical for maintaining the integrity of public administration and citizen trust. In conclusion, the research emphasizes that public administration in Croatia not only ensures basic services and maintains order and security but also continuously adapts its processes and practices to modern requirements and technologies. The system of decentralization enables efficient management at all levels, ensuring that public administration can quickly respond to dynamic citizen needs and implement state policies in accordance with the highest standards of professionalism and transparency.
