University of Illinois lists unpaid FTE adjunct lecturer position (twitter.com)

Wrong. The listing is an invitation to join a pool of potential instructors. If you're selected to teach, you of course get paid.

The practice of offering zero-hours contracts for university lecturing has been very controversial in the UK[1] and other parts of Europe. I think they short-change the students and the lecturers, and represent a long-term risk to the institutions who use them.
