While post-secondary institutions are places of learning, they also employ thousands of people across a broad spectrum of job classifications. This report explores the extent to which workers in Canada’s post-secondary institutions are experiencing precarity. More precisely, it asks whether employment on university and college campuses in Ontario is becoming more precarious, for whom and for what reasons. This report combines quantitative analysis of Labour Force Survey (LFS) data with qualitative accounts of the lived experience of precarity from post-secondary employees. Overall, the LFS data analysis suggests that 53% of post-secondary education workers in Ontario are, to some extent, precariously employed. Specifically, the report identifies a rise in work categories that are more precarious (e.g., research assistants and teaching assistants) alongside a decline in others that have traditionally been less precarious (e.g., librarians).
