The HR crook was still employed in the department at the time the teacher received a notice of "no rehire," and then shortly thereafter he was demoted (I am sure because of numerous complaints against him, including yours truly).

This is nothing short of blackballing, which is illegal, and retaliation by the principal for falling out of her "good graces." The school district is full of these vindictive, incompetent people who pull down over 100k a year and can't be removed because they have an "association" which seems to stick up for them no matter how lousy they are and being part of the district's "inner circle."
