The labour market allows individuals to earn a living throughout their lifetime. When it comes to gendered issues, the labour market is also an environment where different outcomes between female and male workers emerge. Differences between women and men naturally exist because of the biological characteristics related to sex differences. The possibilities of maternity and longevity are the most notable examples. Compared with men, women also have less physical power. In fact, the origin of the gender gap in the labour market goes back to the ‘male breadwinner’ model, typical of an industrial economy, in which women’s role was traditionally limited to homemaking activities (Fortin, 2005; Lewis et al., 2008). Physical skills are relevant to the labour supply for an industrial economy.
