Bearing in mind that these slackers WERE earning $70,000-$78,000 in a town where the median income for regular folks is $22,000, then they really should not balk at giving value for the money. It's another case where the union would rather see people out of jobs then give a little--not recognizing that today's world is much different than when the unions were actually necessary. I can't say that it's a bad thing that they were all fired because they were apparently doing a piss-poor job anyway and were highly rewarded for their incompetence.
It's my understanding that the Chicago school system is in similar straights and that even their teachers can't pass the high school courses that they are supposedly teaching. Maybe if the action above became more widespread, school systems would improve since increasing regulations, student testing, and throwing money at them doesn't seem to work.
