Newsflash: The day doesn't end for many of us in other fields after we 'clock out' either. I sometimes get called at 4am because of network issues I have to assist with. I'd LOVE to have 3 months a year off, as well as almost every federal holiday, and 2 weeks for Christmas.
Yes but is there a connection between effort and reward? My wife could do nothing performance wise that would better herself. She was on the same pay scale as every other teacher. It paid the same for the excellent and terrible ones.
