rar I like to think - I DO think - that any of the schools I have worked in would have made a response to being informed of what happened. There are several issues here: appropriate behaviour from adults on school property, the problematic area of bringing sentimentally important items to school where, unfortunately there is always the risk of loss / damage, the ongoing pastoral situation re the 'offending' father -and in particular his child and the potential fall out with / the emotional needs of the other child.
I am not suggesting that the school get involved in any other way than pastorally, but if I were class teacher of either / both boys, I would appreciate being informed so that I could be supportive to them.
With child protection issues in school, it is when we record incident after incident and paper trails are created and grow that further action eventually gets taken. In the incident that gilly witnessed, my greatest concern is for the child of the offending parent and I think it is worth this incident being reported and recorded for his sake. We don't address inadequate parenting overnight, but through gradually building a picture of failures, something may change in time.
Anger management!!! Help needed.
