JackofAss, what is your new job?
I'm on the fence about teaching. I've been doing it for 9 years. I don't think I want to do it for the rest of my career. Why not? Well, here are some things I dislike:
Lack of respect from students (many students do respect me; in fact, most do. but the few that don't make me hate teaching sometimes).
Lack of support from administration (they just don't stand up for their staff).
B.S. from parents (when I was a kid, parents sided with the teacher; today, parents side with the kids, do their kids work, beg for their kids to be able to turn stuff in late for full credit, call admin to get kids out of trouble, etc.)
Meaningless change. Most of the "changes" in education have been calling an old thing by a new name, learning a new process to do the same thing. Plus, we gradually have become accustomed to expect less and less out of kids. I'm not against adapting to society and having real world applications, but students needs to learn. They need to know things. We shouldn't just learn skills. I think kids need to memorize some things. There are things you need to know to be an intelligent human being. There are things you need to know how to do to be an intelligent human being. I hate stupid people who say things like, "I stopped listening as soon as you started talking numbers because I just can't do math." Yes you can. Anyone can do math.
What else do I hate about teaching? Not the schedule. The schedule is great. In the winter, when I'm not coaching, I love being done early. I love going to work early. I love the time off.
But what else do I hate? Probably lots more. Those are just some examples to get you started.
