I have answers for every objection I can think of. If you have an objection I have not addressed, then post it in my forum . If I can't think of a solution, then maybe one of my readers can. Most community colleges hire adjunct professors nowadays, instead of full time professors. Adjunct professors only teach one or two classes, and we don't get benefits.
High schools hire part-timers now, too.
From a teacher's standpoint, it is far easier to take on a temporary position knowing how long it is going to last. Currently, many temporary positions are cancelled midway through the semester. My husband is a community college student. He works full time days and he takes evening classes. His major is electronics.
