I don't usually disagree with you, Humus, but this post is aggravating.
I have nothing against charter schools either. However, since their enrollment is often based on parents caring enough about their children's education to actively seek admission for their children, that leaves public schools in the unenviable position of educating those whose parents don't really care.
(Before anyone misinterprets my meaning, I KNOW there are many parents of public school students who DO care, and are involved in their children's education. As a public school teacher, I appreciate their support and involvement.)
So, when studies are published about the success of this charter school or that one, legislators and business people opine that public schools should be modeled in the same way. It's frustrating to those of us who are expected to have the same level of success with students whose parents don't support their studies, ignore school/district policies, and prefer to be nonentities, and sometimes even barriers, in the educational process.
As for the unions, I am glad that I have a union and I'm a proud member. One fallacy that permeates the media is that unions keep bad teachers in their jobs. That's so wrong. Any teacher, tenured or not, who is not performing his/her job satisfactorily can be dismissed with the proper documentation. In fact, that documentation is not so hard to amass. True, in most contracts, teachers are entitled to a remediation process before dismissal, but it is absolutely possible to remove a teacher who shouldn't be teaching.
Well, then, how are ineffective teachers allowed to continue in their jobs? IMO, you'll have to ask their administrators. If teachers on their staffs are ineffective, or even harmful, what have the admins done about it? How are they monitoring their teachers? Before tenure, teachers can be dismissed without any reason and the union can do nothing about it. After tenure, all it takes is a trail of documentation and a failed remediation. The union cannot protect against that. I wish the media would quit blaming the union for protecting bad teachers. The process is there, but too few admins/districts act on it.
I also agree that there is a lot of waste and inefficiency in government and public schools. Much of the waste and inefficiency in public schools is due to the government. Education has become a big business, and the rich get richer while the poor get poorer. A whole new industry has been created in response to federal mandates, and I'm too much of a cynic to believe that one hand is NOT washing the other.
Unfortunately, to many of us teachers, it feels as though the weight of all the failures in education are on our backs. We, who have the smallest voices in education, are most often the targets of blame for all ills.
ETA: Sorry for hijacking, OP. I've been there with my sons' high school. I agree it's wrong and I think it's unethical.
