Well exactly, and the democratic party is basically a mouthpiece of the teacher's unions. To criticize the teachers union at all would quickly remove you from the democrat party. My mom has shifted rightward a lot but is not a die-hard republican. She is a die-hard never democrat though. She votes straight ticket against the voter's pamphlet issued by the California's teacher's association every year.
So the teachers’ union who is there to protect the teachers, is against the teacher? Do we have a source for that?
I've read some other stories like this commented throughout the post. It's not far-fetched, cause even if a union is really for the teachers, it has to choose its battles.
