Dear Mary: My son’s school principal is out of control and roars at pupils and even staff

I am concerned that the principal in my son’s school is a bully. He has been overheard verbally abusing one particular teacher, culminating in him roaring at her to “get back into the classroom and do the job you are paid to do”. This was done, in my opinion, to one of the best teachers in the school. The woman was bawling, understandably, and not given enough time to compose herself. This was not fair on her or the children.
