Get your facts straight about the "school unions"
First Tom, almost all states have laws against teachers striking. The strike threat is probably the top source of power for unions. The teacher's unions at least in our state don't seem to be very effective at getting any power or pushing money towards teachers because there's a very small pot of money in the first place to haggle over.
Just what did the NEA get for teachers over the past few decades Tom? From what I can see, they lost all the major battles.
