So you are for taking away their right to assemle and organize? What kind if facist are you? Leave them their right and negotiate with balls instead. If the Union in this case doesn't agree to the terms placed on the table fire them and replace them with Non Union Teachers.
No. I disagree because of practices of the Unions themselves forcing only union members to work. Most places, if you are a teacher you MUST be in the union. There are no exceptions from my experience. I seriously dislike that form of strong arm tactics and collective bargaining tool.
If teachers want to form together bargain a few things that is fine, but not as strong arm union. There is a difference and you don't seem to understand that.
Employee's and employer's should have the right to determine who works for them and what conditions they will work. Don't like working for X employer? Go find another that is willing to be more accommodating to you. Enough workers do that and X employer won't have any to work for them and will change their ways. On the opposite, if you are overly demanding more from your employer than any other employee is asking, you may have a hard time finding a job until your expectations come back to reality.
Unions had a definite need in a time and place. For teachers, it was when schools and places to work were limited. At one point, there was a whole lot less schools in certain areas where prospective teachers could work. Thus they were at the mercy of the employer if they wanted to teach without unions. This is not exactly the case now in the majority of this country.
