Thanks for the replies.
My wife exchanged emails with the teacher and she acknowledged the fact that there have been multiple reports of bullying by these two kids from other students and parents. The solution was changing desks but then incidents moved to the lunch room. Then to the playground. This specific child of our three is honest to the point he tells on himself if he does something wrong. I'd be a lot more hesitant if it was one of the other two.
These may get taken care of or they may escalate. I just have a bad taste in my mouth from the district in general based on how the "stabbing" incident was handled among other things over the years. Also hearing things from our two teacher neighbors about the state of the district and being handcuffed if things do escalate. It may just be a waiting game right now.
I was just hoping we'd at least make it though the first years of elementary before dealing with this crap again.
At this point, your teacher should have shared the voluntary sign up to share contact info with other parents list. Join and send out a message (minus the offenders families) about class behaviors and encourage open dialogue. Share that you've gotten some vague information from the teacher about misbehaving reports and you would like to compile them with more accuracy as they are ongoing. Use a burner email and simply include your real email in the reply all list.
Kindergarten is far too important of a year to establish liking school or fearing school. This needs to stop immediately.
Admin should be monitoring lunchroom. My elementary kids, MS, and HS kids all have active monitoring going on by admin.
Which building is this? Maybe we have been blessed by very good admin and you got a bad draw.
And, yes, teachers are relatively handcuffed in the responses they are allowed to take. Escalate in a way that the teacher isn't blamed.
