My side gig is teaching at a major university as part of a third-party contract with outside businesses. I'm still university faculty, so have to do all the HR training, maintain my credentials, etc, but my pay is a little different...

The university literally doesn't pay us for the classes. The syltudents have to pay a $215 "lab fee" directly to us that's split between me and the business. So I get paid $107.50 person student per semester while the University gets paid about $3,000. Our business provides the staff, facilities, course materials, and even the liability insurance, so the university's only real expenses are having the course listed and taking the tuition money.

My official title at the University is "Lecturer : Unpaid"
