In constructing and engineering, workers with different organizational belonging are working together, often on a project-by-project basis. When precarious workers enter an organization, existing power relations, organizational practices and gender relations are challenged and changed. Our aim is to investigate patterns of segregation and gender inequality in a technology-intensive organization responsible for building and operating all national roads and railways in Sweden. A questionnaire has been administered to regular employees, contracted staff and self employed consultants working in the organization. The analysis is guided by the theoretical framework of ́inequality regimes ́ as presented by Acker (2006). The results indicates that intersecting patterns of inequalities based on gender, age and terms of employment is present, and not only persist but even increases when precarious groups of workers are joining the organization. The group that stands out is the self employed consultants; they have the highest salary, lowest education, highest mean age and only a single woman out of 199 in this category. This group of male workers seems privileged in many ways as they express that they are highly valued and encouraged by the management compared to the other groups. These results call for further analysis of the intersecting patterns of inequalities in the organization on aspects such as goal achievement, the self-image, collaboration, and knowledge transfer.
