Highlight the issue of pay and job security for part-time professors in academia.
My last pay at Centennial, in 2012, with a PhD from a Canadian university, was 2300 CAD, for 45 in-class hours. Extra work, including syllabus preparation, exams, grading, etc., is not paid. If you are a part-timer, you get to teach maximum 2 courses per semester. This is much, much less than 39K. Otherwise, you fall into a so-called partial-load category, which pays significantly better (see the article above), and which, understandably, the administrators try to avoid. Where is here social justice? Academia is a bunch of hypocrites.
