Reform of the Croatian legal system and the adjustment of its legislation to EU law is one of the main conditions for the Republic of Croatia to be able to join the Union. This paper analyses the existing requirements for gender equality inside the EU, the current situation in the applicant countries and the existing problems and challenges for states that are only on the way towards European integration. In the Republic of Croatia gender equality is not guaranteed to a sufficient extent, which has resulted in negative public reactions from NGOs and organisations for the protection of human rights and the rights of women. In addition, individuals are exposed everyday to various forms of sexual harassment in the workplace, in schools, universities and public places. So far, except at the constitutional level, no kind of legal approach has been adopted to guarantee gender equality or freedom of sexual orientation, which is an obligation of Croatia according to international treaties and the SAA.
