Refugees are people who flee their country from armed conflict or persecution, and find themselves in a life-threatening situation, which is why they go to other countries in search of security. Migrants are people who do not go to other countries due to the direct threat of persecution or death, but do so mainly for economic reasons, better jobs, education and the like. Migration as such is a constant in living beings, present from the very beginning, and regardless of the causes of migration, it represents an instinct for survival. In 2015, Europe faced a refugee crisis that, in addition to millions of refugees, brought with it a number of economic, political and social problems, putting its citizens to the test of humanity, openness and tolerance. As the external border of the Schengen area and one of the routes of migrants, Croatia itself faced the problem of taking care of refugees, although they saw Croatia as a country of passage, but not of staying. The issue and problems around refugees / migrants are still present in some countries that have become hotspots, and the issue of the pushback method of solving the problem of accepting refugees and migrants is also topical. Numerous NGOs and civil society organizations have become involved in working with refugees and migrants, and multiculturalism and social workers have proved important as promoters of ethnic minority equality. It is the social workers who must understand the culture of the minority without prejudice, and include them in the domicile society, raise awareness of the community and thus lay the foundation for the social integration of refugees belonging to different cultural groups.
