There has been a visible trend of increasing migration from Ukraine to Poland since 2014. Immigrants are becoming a part of the Polish labour market. It is interesting to look at immigrants from the perspective of challenges faced by human resource management processes (HRM) in the enterprises employing them. Thus, the purpose of the study was to answer the questions: What are the characteristics of migration from Ukraine to Poland? Are there any studies in the area of human resource management in relation to the issue of migration of Ukrainians to Poland? What the directions of future research in the area of HRM in the context of migration of Ukrainians to Poland should be? In the pursuit after the above goals, one has used, among others, literature research, analysis of foreign research results, own pilot studies conducted with representatives of employees from Ukraine and their employers.
