The paper that contribute to and maintain segregation and discrimination of women at the labour market. Although women are formally and legally equal to men and are increasingly entering the labour market in todays societies, there is still a distinction between male and female occupations (horizontal segregation), the gender pay gap and barriers that impede women’s promotion at higher positions (vertical segregation). Due to the glass ceiling phenomenon, women are very slowly and difficulty promoted at the highest positions at the labour market, and have to prove themselves more than men. Gender stereotypes, patriarchal values, beliefs, attitudes, socialization and prejudice explain this phenomenon. Due to the mentioned reasons, employers are also reluctant towards employment of women and prefer hiring men because of beliefs that is more likely that women are going to be absent from work due to family obligations. A number of theories explain segregation and discrimination against women at the labour market. Female cyclic type of career and her primary responsibility for family and children are a very important factor that prevents women promotion at work, sometimes even their re-entrance at the labour market.
