In the fight against youth unemployment, the European Union brought the Youth Guarantee program into force immediately after the economic crisis in 2013. The European Commission, through the Recommendation of the Council on the establishment of the Youth Guarantee in 2013 and financial assistance wants to ensure that all young people get the opportunity for training, continuing education, or employment within four months after leaving education or unemployment. This thesis points to the development of the Youth Guarantee program at the level of the European Union and analyses the similarities and differences in the implementation of the Youth Guarantee program in three member states - Sweden, Slovenia, and Croatia. In Sweden, young people are most often faced with short-term unemployment and measures are thus more oriented towards less employable young people, such as young people with disabilities. In their implementation plans, Slovenia and Croatia focus on advisory work with young people and the inclusion of young people in the labour market through the measure of public works and by subsidizing the wages of young employees. Compared to Sweden and Croatia, Slovenia stands out as the country with the most comprehensive measures aimed at activating the young population, and it stands out, especially with the measures of young entrepreneurship and the prevention of precarization in the labour market. The success of the program during the period from 2013 to 2019 is visible through the reduction of youth unemployment in all three countries.
