Teacher vs preschooler

Gab

So I made a post yesterday explaining the situation at my new job about a teacher, dragging a student across the playground due to him not listening. I’m fairly new at this job. I want to say I’m barely on my third week and this happened last Friday the dragging of the student. Everyone on the post told me that I should bring this up to the Director. Which I will. since I am fairly new here I’m still in training for mandated reporter. I know for sure. I will be letting the Director know but my question is should this be reported? Once I complete my mandated reporter training I can report to higher ups meaning like CPS in them for any suspected abuse. I guess my question is would this one incident qualify? I am a mother and I would definitely report this, but I guess I’m looking at it from another view, thinking of this teachers career technically being over with due to my fault
