A teacher has a right to speak out against curriculum they do not support. The entire basis of an open and free thinking educational system is to be able to question. Common Core supporters seek to remove any and all dissent and critique from those who are best to analyze the outcome of this program... the teachers. This is not a process that speaks to the liberties we are guaranteed by our Bill of Rights and Constitution.
For what it’s worth, I have 25+ years experience as an urban public school teacher. I HATE Common Core. The standards it promotes is bad. And federal intervention in local issues is in itself wrong.
My point on this thread was more general. Employees should have the right to speak out as private citizens. But employers should have some rights too.
