Introduction The various forms of discrimination relating to occupational gender segregation are more subtle as well as more delicate to address with specific actions. According to the ILO, women represent 40.4 percent of the worldwide workforce. However, that proportion is not reflected when investigating occupational groups within the various sectors: 46.3 percent of employed women work in the services sector, 35.4 percent in the agricultural sector and only 18.3 percent in the industrial sector (compared to 26.6 percent of employed men) (ILO, 2009). The specific sectors in which women employees are the vast majority – secretaries, teachers and nurses – also are poorly paid work areas. And even within these jobs they are paid less than their male colleagues (IWPR, 2009). This fundamental under-evaluation of women's work results basically from two facts. Firstly, women's primary responsibility for unpaid care work such as children, education and basic family services seems to channel them into similar working areas in the labour market (UNIFEM, 2005). Some researchers refer to differences in occupations between women and men as the selection effect (Petersen and Snartland, 2004).
