We focus on the reproduction of gender inequality in the labour market, analysing everyday practices of social boundary demarcation that exclude women from accessing resources at work. We argue that women's diminished position in the labour market – or gender deficit – is a result of taken‐for‐granted, day‐to‐day practices, conditioning the distribution of resources. Taking Chilean professional women as a case study, we focus on labour market practices that uphold gendered evaluation criteria, reproduce social classifications, and engender exclusion through social boundary work that limits women's access to labour market benefits and rewards.
