Deleting-- When I first read, I didn't see the last page of posts. I was responding to something said two pages up, and it's already been discussed.
I just want to say--Comparing teaching to other jobs, and how they can't pop in a video for a half hour isn't fair. I taught AP seniors as well as regular classes. Maybe you can't pop in a movie for a half hour, but do you come home with 5 hours of work, creating tests and exams (if you do, you are probably compensated with a decent salary-- my salary in an urban high school was so low that I made just $100 more than it would have cost to put two children in daycare). Grading projects and essays, Getting grades finished for report cards (there were nights I never went to sleep because I had so much to do). On Saturdays, I had to take my mock trial team downtown for their competitions, plus spent many nights and Saturdays at school with them while they were preparing for their competitions --- not compensated. In the 2 months of summer that we have "off" I was sent to week long training sessions out of state to get training for the Advanced Placement class I taught (uncompensated), I spent many many days getting my classroom ready, making up unit plans, researching, taking graduate classes that I had to pay for to keep my certificate active. Believe me, I didn't feel bad every now and then, ending a lesson on filibustering showing a 40 minute West Wing episode about a filibuster. It was good for the kids, and I was able to get a little grading done. OP--Don't let some of the comments get you down.
