Who's exploiting Margaret Mary Vojtko?

Officials at Duquesne University are disputing some of the facts of the story of Margaret Mary Vojtko, a longtime adjunct professor there who recently died sick, uninsured and impoverished. But they don't dispute labor lawyer Daniel Kovalik's original account of her poor pay and lack of benefits:

I called Adult Protective Services right after talking to Margaret Mary, and I explained the situation. I said that she had just been let go from her job as a professor at Duquesne, that she was given no severance or retirement benefits, and that the reason she was having trouble taking care of herself was because she was living in extreme poverty. The caseworker paused and asked with incredulity, "She was a professor?" I said yes. The caseworker was shocked; this was not the usual type of person for whom she was called in to help.

Of course, what the caseworker didn't understand was that Margaret Mary was an adjunct professor, meaning that, unlike a well-paid tenured professor, Margaret Mary worked on a contract basis from semester to semester, with no job security, no benefits and with a salary of between $3,000 and just over $3,500 per three-credit course. Adjuncts now make up well over 50 percent of the faculty at colleges and universities.
