The development of business on the global market also affected the migration of workers. As in other countries, in the Republic of Croatia there is a demand for foreign workers due to the migration of the Croatian population abroad and the lack of skilled labor in the territory of the Republic of Croatia. In order to be able to employ foreign workers in the territory of the Republic of Croatia, it is necessary to meet strict conditions related to entry, exit, residence and employment, which is a problem for owners of small and medium-sized enterprises. The theoretical framework of this thesis was based on the research of available information from scientific and professional literature and Internet sources in order to confirm and/or deny these complaints of entrepreneurs through secondary and primary research in the territory of the Republic of Croatia. The empirical research related to one agency for the employment of foreign workers and a sample of 10 small and medium-sized enterprises from the production, construction and hospitality sectors from the area of continental Croatia. The president of the agency, 10 business owners and their 102 employees were interviewed. The results of the interview and survey showed that the legal regulations and the amount of documentation that needs to be collected present a significant issue, which is why employers often give up on hiring a foreign worker. It is emphasized that foreign workers are not loyal, so employers assume the risk of invested time and additional costs in order to meet all the legal requirements for the employment of a foreign worker, and they often give up on the idea very quickly. Foreign workers have enough knowledge of the English language to communicate, but domestic employees need much more time to explain the logistics to them. Therefore, employers are recommended to carefully study the legal regulations when hiring a foreign worker, to start the hiring process on time and to prepare the current domestic employees for the arrival of the foreign worker.
