This graduate thesis analyzes the discrimination of women in career advancement and employment in managerial positions. Problems also appear on the way to a leading business position, where women, despite their education and abilities, encounter barriers in their further advancement, but they do not stop even when a woman reaches such a position, but she abandones it because of too much pressure. The reason why women are considered inadequate is mostly found in stereotypical notions and conscious or unconscious prejudices against women in managerial positions, leading to so-called glass ceiling phenomenon, or the level of organization that a woman can progress, after which her further ascension to the hierarchy is difficult or impossible.The Republic of Croatia as well as other members of the European Union has recognized this problem as well as the importance of women in the further development of the economy, and have the political determinants and business guidance turned to combating the problem of discrimination against women, as well as to the development of entrepreneurship with specific measures for women's entrepreneurship.Today it is not questionable whether women are as capable as managers because it is proven that in almost all aspects of leadership and management women are as good as men or even better. It became clear that the notion of power as well as the notion of leadership need to be refined in order to make the usual way in which in the past only men were prone to not observed as the only possible way in the modern business world.
