I think it is. It has not been studied as much in Canada as it should be, but 10% of CUPE members work in a post-secondary setting, many of them teaching classes. At York University, where we had a strike, unfortunately, for 13 weeks, 58% of the teaching is done by CUPE members who are teaching assistants and can't get tenured positions. The average wage is less than $30,000 a year. That's 58% of York's teaching, and York is a renowned institution. The 65,000 CUPE members who work in universities across Canada are not all teachers, but many of them are. It's taking them longer to get started in life.
