On NOW!!!
Listening now. I have some experience with rotten principals. The most important thing is to document every encounter with the school system, write everything down like a reporter/attorney. A diary of sorts, a paper trail. I was escorted off school grounds under threat of arrest while eating lunch with my third grader and banned from the property. I got that partially rescinded and then went to a school board meeting with a handcuff on. Never said a word. I just jangled my new ‘bracelet’. And then, I got her. She was plastered all over the front pages for weeks. She picked the wrong person. My third grader is a grown woman now. But that woman NEVER taught again, much less ran a school.
You’ve got good friends behind you on this, you’re lucky. I had to do it alone, I was surrounded by chickens.
