This article reports on a study investigating the link between education and work. Instead of looking at the labour outcomes of graduates, the study examined the qualifications held by workers in technician- and professional-level jobs from three types of occupational fields: regulated, applied, and general. The approach shifts the focus away from the supply of qualifications to the way qualifications are used in the workplace. The findings show evidence of disparities between qualifications and work levels and of the presence of obstacles preventing workers with additional qualifications from securing access to better jobs. Overall, the findings show that the structure of the labour market shapes how workers and employers make use of qualifications. They highlight some of the limitations of human capital theory in explaining the links between education and the labour market and call for a reframing of the purpose of postsecondary qualifications.
