In the Republic of Croatia, the concept and experience of ethical business is still not at sufficient levels. Croatia faces daily violations of consumer and employee rights, lack of care for the environment and society, and insufficient awareness of environmental protection. Despite the fact that during studies more and more attention is paid to topics and courses in business ethics, there is not enough knowledge about students' perception of the importance of ethical business and the impact of socially responsible business on their choice of employer, positive attitude towards the company, motivation and/or job satisfaction. Based on the available literature and the implementation of various research, the paper investigated the perception of the sustainability of ethical and socially responsible business (hereinafter: CSR) among students of VERN' University and the experience of the work of socially responsible entrepreneurs. The theoretical part of the work is based on primary and secondary sources of information, and the research part of the work was carried out based on the study of the available literature related to the work experience of social entrepreneurs in Croatia and world and a survey questionnaire. By collecting the work experience of socially responsible entrepreneurs, it can be concluded that social entrepreneurs are driven by a passion for solving social problems, and are characterized by great determination, willingness to take risks, experience and the creation of partnerships and cooperation. Based on the results of the research, it is evident that the respondents mostly have a positive perception of ethics and socially responsible business and believe that CSR affects the sustainability of business, financial stability and the positive image of the company. However, still a large number of VERN' University students do not have practical experience, that is, they have not attended education and participated in CSR activities that are not exclusively related to college education.
