You are delusional. Teachers do not just work, "worst case? 8:00 to 3:00" as you state. That is the BEST case. Those are the hours they are in school. But teachers are also expected to prepare tests, grade tests, meet with parents, etc. I would say 10 hours a day is average, or perhaps even below average. 12 hours a day, and quite a number of hours on the weekend is more typical!
But with all that said, the wage should be what the school is willing to pay, and what the teachers are willing to accept for the job.

It's usually about 12-16 hours a week on weekdays, and about 10-20 hours a week on weekends often for me.
