I guess teaching must be the only profession where those pulling their weight are not immediately let go - right.
I believe those not performing in any job, regardless of what it is, should be given notice to lift their game & if not, given the flick. Judging by the poor quality workmanship and service I see in just about every facet of life I'd guess this dosn't happen.

One of the problems facing educational districts (at least in oz), is that if they were to get rid of all the slackers, there wouldn't be anyone to replace them. It's not a job that has people beating down the door. So you're left with having someone vaguely competent in the job or no one at all. Easy to see which option they choose.
