I actually was a professor at one of these for a few years. Felt guilty taking my paycheck as full time meant that I performed class instruction 10 hrs per week, 28 weeks per year. (2.5 hrs per class X 4 classes per week) My office hours were between my classes.
My last year there, they rearranged my schedule so I only worked Tuesday and Thursday (yes, I still was full time.) Didn’t even set foot on campus MWF. Unfortunately, my teaching schedule conflicted with court appearances for clients which was far more lucrative.
There was absolutely no pressure to publish or perform research at these institutions and the pay was much higher than most prestigious private universities.
I often joked that after working as a professor for the state for the state, I would never get a real job!!!
By the way, after you teach a subject one semester, there is very little prep time for class, and with computers doing much of the work, even exam grading is a piece of cake.
I taught as a visiting assistant professor at one of the universities in that system for a year—I got paid about what I got at other temporary positions I had in those years, but the permanent faculty seemed to be paid quite a bit more than the faculty at comparable universities in other states. It was a four-course load (12 hours/week).
