There is nothing personal. I have replied to your comment requesting a rebuttal to an issue which was obvious you are not familiar.
Your understanding of a free market must be where one party is at the mercy of a dominant party. In a free market both parties are equal in the negotiation and if one party do not like the settlement they are free to leave. That is the way it works with teachers. School systems loses teachers every year due to other systems offering better compensation. Teachers signs a new individual contract every year with their school system. School systems can dismiss a teacher with cause at anytime for a violation of the contract terms. School systems are in competition with other school systems, both public and private, for the better teachers.
