Fortunately I have no other students with behavior challenges in my class so no concerns there.
You're very fortunate in that!
But the other kids can start to think, "Johnny gets away with ___. Why am I bothering to put in effort?" Been there, felt the results of that.
Yes and no. The child was here but the teacher is gone. Both special education teachers from last year are gone. Both the principal and assistant principal from last year are gone. My principal is a first year principal. Both of our special education teachers are first year special education teachers. We're also currently supposed to have three special education teachers and only have two.
Is the teacher still in the county? Does anyone have his or her phone number? It's a rare teacher who isn't willing to help another -- and the more information you have, the better off you are.
General question to all teachers - wouldn’t the union help with this if someone was fired for calling 911 in a true emergency and the teacher was in fear or their life or that of their students?
The majority of teachers aren't in union states.
All behavior is communication. This child is acting out as a coping mechanism due to a stress response to a situation he cannot explain (fight or flight, he obviously goes to fight...this is involuntary so don't blame the kid) ...
Yes, and kids aren't always in control of their emotions /actions. They're KIDS.
I remember years ago I had a girl who came in and was absolutely horrid to me -- out of nowhere! I had to call for an administrator to take her out of class. At the end of the school day she came down the hall, head down, avoiding eye contact. She shoved a note into my hand and kept walking. The note apologized, told me about something genuinely horrific that'd happened at her house before school (so bad and so unique that I won'to even repeat it), and said "I know you weren't to blame, but I took it out on you."
The fact that you have so many new staff is very telling. And having unfilled special education positions is unfortunately all too common. This means the teachers you do have are dealing with too many cases. Your new admin are probably doing all they can to keep their heads above water. If you try to deal with everything without help, they will let you. Talk to the special area teachers (PE, music, etc) and enlist their help.
I retired at the end of last school year, but it's been about three years since our Special Ed department has been fully staffed. We're in a teacher shortage again, and Special Ed seems to be the hardest to fill -- that's certainly a big part of this problem.
I strongly suspect no one is sitting around saying, "I just don't care"; rather, it's almost certainly a matter of not enough resources.
