Abstract
This paper analyses the phenomenon of gender discrimination in the science, technology, engineering, and mathematics (STEM) sector, which has always been known for its strong segregation, both horizontal and vertical. Our purpose is to uncover more hidden mechanisms of gender discrimination, such as those that refer to the implemented organizational models. The sample used is the universe of the INFN (National Institute for Nuclear Physics) division in Naples (Italy). For our study, we used semi-structured interviews and an interpretation model as one of the structural inferences. The results show that the organizational models adopted by INFN penalize women, but often men too, which can be traced to the way society and the labor market are structured. In general, the interviewees showed enthusiasm to work in the research field, even if in this context the adopted work organization model was limited and restricted, unable to value diversity and transversal skills. A different perception of time management between women and men leads in the former to a feeling of dichotomy as a source of malaise. Consequently, it can be said that there is a form of inequality (or discrimination) related to women’s well-being and that they have a worse quality of life.
