Human resource management is the key to efficiency in every organisation. Employees are no longer viewed as a necessary expense, but as the primary and main resource that organisations rely on. In order to remain competitive, organisations must recognize the importance of human resources and acknowledge the relevance of investing in them. Human resource is the main differentiating factor between organisations. The success of every organisation depends most on the knowledge and skillsets of its employees. This indicates the importance of employee care as the key component of competitive advantage. The aim of this thesis is to compare human resource departments in two different countries within the European Union. The two polyclinics analysed are located in The Federal Republic of Germany and Croatia respectively. This aim of this thesis is to compare the similarities and differences of the human resource departments in two different countries and to emphasise the importance of employees in the functioning of the organisations as wholes. The research conducted as part of the thesis showed that the owners and managers are conducting their duties as heads of human resources in the aforementioned institutions extremely efficiently. The main differentiating factor between the two polyclinics is the fact that one polyclinic practices formal relations exclusively, while the other combines both formal and informal relations depending on the situation at hand. Both clinics understand the importance of both material and immaterial methods of rewarding employees, as well as the importance of managing conflicts with care. The employees of both polyclinics are greatly satisfied with their workplaces and managers, but they do leave room for certain improvements. Even though there are some weaknesses, most employees are extremely satisfied. Conclusions that can be drawn from the research are that the owners understand the importance of investing in the quality of human resources and know how to manage them.
