The task of business ethics is to emphasize the structure of the field of ethical business. It talks about the concepts of socially responsible business, corporate citizenship and sustainability, which are often used in modern times with the aim of applying business ethics. Companies must take care every day to make ethical decisions. Ethical dilemmas are situations in which an individual finds himself who has to decide between options (most often there are two) that contain a violation of moral principles. With globalization, the world has become a "global village" with a number of opportunities for each inhabitant. The contribution of globalization is visible in the achievement of the desired stage of existence, the realization of political, technological and/or economic freedoms. There are a number of theories that describe the reasons for the emergence of migration, and among the most important is the neoclassical theory which focuses on the aspiration of migration with the goal of achieving the desired income. According to the number of immigrants per Croatian county, it is evident that the leading county in terms of foreign immigrants is the City of Zagreb with as many as 13,628 immigrants. Thanks to globalization, labour mobility is easier than before. People who until now worked in poor working conditions, high unemployment rates and low-income levels are migrating in a targeted manner to countries with a lower unemployment rate and higher income. Like a number of other world countries, Croatia has a need to "import" foreign workers. The employer's rights, as well as those of foreign workers, obligations, supervision and misdemeanour liability are specified in the Occupational Safety and Health Act.
