The New Debate on Merit Pay

It seems like everybody is crying out for this teacher merit-pay idea, if only it weren't for the big, bad teacher Unions who are in the way.  Apparently, the Unions' only real interest is in protecting a bunch of miserable older teachers who can't teach, and only show up because they're after the free money.

Well, I'm not buying it, mostly because I don't know any teachers who are like that.  The truth is that most miserable teachers who hate kids and hate teaching get out of the profession.  It's not exactly a low-stress job.  I think the life span on a bad teacher tops out at about one year.
