This loathsome whale is Karen Lewis, the head of the Chicago teachers union.  In a recent speech, documented here, she reports that:

1.  While a teacher, she would lie to parents about the performance, or lack of it, of their child in her class.

2. She would then use these lies to make a "hostage" of the child.

3. She advocates that teachers organize to make the job of any principal that they don't like as miserable as possible, with the aim of getting rid of that person.

Unbelievable.

As one commenter to the article said, the solution to immoral sweating beasts like this is giving parents the freedom to move their children to charter schools or religious schools, along with the public money to support that child's education.  

Starve the beast, and you might get better education.
