Did I act out of line?

[WhimsicalLayer]

We seen to have stomach bugs and covid resurfacing at work and we’re on skeleton staff. Limited SMT available in an emergency. Today they were near enough all out. An incident took place between two girls who were fighting. One ragged the other ones head and smacked her. Call her student A
The student injured student (student b) hung back after school and we filled in the incedent report as usual and was visibly upset. Took the statement. Did the procedure. Well not me but others did.
So, student A was already being a bit silly at the start, so I rang home and said “your daughter wasn’t following rules from the start of the lesson. I also wanted to alert you of an incident that took place at the end of the day whereby they physically hurt another student. I will be escalating it and you’ll hear from the school in due course”
Later on I sat back and thought “was that my place” bare in mind we had 0 SMT today. They’re basically all ill and one who we had left very early
Was this above my station? Should incidents be dealt with by designated staff only?

Not today, sorry. Yesterday**

Maybe just loop SMT into what you told the family so they can be prepared to deal with the situation on their return. This doesn't sound too out of line in my opinion. You didn't undermine anyone - that would be out of line!

Thank you! I spent most of yesterday worrying about what I said, thinking, “oh no, maybe that was totally above my station to do that”. I did pass it on via email and no one got back to me. But I suppose my fear, after I made the call, was disclosing what happened. I was just concerned that maybe I should’ve waited till SMT did a full investigation first??

You disclosed a fact not your opinion/perception of the event. I would think this would be acceptable.

To be honest, I feel like there ought to be someone in school who can deal with an assault between children there and then. Depending on the severity of the assault, it may not be appropriate for the children to be in class together in the afternoon, for example.

Do you have a DSL available in an emergency?

To be clear, I don't think you've done anything wrong, but I am questioning whether the school should be open in the circumstances you describe.
