Cons, since you don't support collective bargaining...?

Yes, I would support collective bargaining by parents with teachers. I have no doubt for the amount of money today's incompetent teachers are being paid, I could hire a better instructor. $100000+ salary for a substandard job is what many taxpayers object to. Teacher's unions, and other government unions have resulted in overpaid, under-worked, and non-motivated workers. The union thugs and thieves need to realize, sooner or later, they are going to run out of other people's money (taxpayer) to spend.
