Stupid bought and paid for Politicians SUCK MORE !!! . My apologies to any outstanding teacher who is really trying to do the best job possible within the corrupt shoddy system that requires them to unionize or not teach. You have to do whatever to keep your job and income. I get that, but if you are blind to how screwed up the system is, ...... then shame on you.
