Everyone knew it. She couldn't be fired because unions.
Anti-union canard #30147. There is nothing about unions that prevents people being fired for cause. And do you honestly think that the teachers that came after Mrs-can't-do-arithmetic were happy to do twice as much work to catch those students up?
I believe that the reason there are so many anti-union today is because they have often failed to police themselves.
See above. If you joined a union, would you suddenly think "boy, I wish Stan over there would start slacking off, so I could do my job plus his" - probably not. Your problem isn't with unions, your problem is with poor administration.
Unions should *not* protect teachers who fail remarkably at their job.
They don't. Again: there is nothing about unions that prevents people from being fired for cause. What you have been propagandized to support is firing people without case.
Between complete shit teachers and unbelievably shitty teaching practices, is it any wonder people are looking for "something better"?
Better would involve higher taxes - you get what you pay for. It does not involve charter schools, where your can't-do-math teacher would be happily employed under an ineffective or chummy administrator.
Sure, their are and will be problems with charter schools but we're seeing giant problems with the corruption of the public schools today for which we don't see an immediate remedy and we can't put our kids in stasis while we fix this problem.
You might as well drink Drano for an ulcer. Makes as much sense as replacing public schools with charters. And you didn't answer the question - what happens when Billy Bob starts beating the shit out of your kid, but nothing happens because his dad is on the board of the charter?
