This is a fairly classic situation at primary school I'm afraid. It's absolutely infuriating.
Having been through this with DS where I didn't really understand and feel really bad that I didn't back him enough (i let everyone talk me into the "oh the kids must just avoid each other/they're all equally to blame" crap) and now with DD as well (she's not being bullied as such, but there are two very unpleasant children in her year group who sor tof bully all the rest of the children at a low level), my advice is:
- Make sure your child knows you will support her. she should avoid the bullies etc but if the bully does cause a reaction and the school calls you in, you will support her.
- tell the school firmly but politely, in writing as well, that you expect your child to be safe at school and that it is their responsibility to ensure this.
- Consider writing to the Board of governors or local Academy management (I haven't done this becuase our board and academy are both shit but I am considering putting it on record when DD finally leaves at the end of this school year).
The other thing that I learnt is that sadly, these bullies are actually the ones who will suffer long termn and I actually feel quite sorry for them. In DS case, two of them came to the same high school with him and the one mother in particular was very quick to use very negative language about DS and claim that her child's behaviour was justified.
In the first term of Year 7 these two children attempted to pick up the bullying and getting Ds into trouble that they'd so successfully implemented in primary school. The first instance was in the FIRST week of Year 7.
COMPLETE FAILURE. At high school there was a much more robust process in place to assess what had happened, including witness statements from other children and, to my amusement, CCTV. DS was completely and totally exonerated of two accusations and these other boys, and a bunch of their new cronies, got a range of punishments ranging from detention to exclusion.
Unbelievably, about a year later, the one child tried to start it up again and, again, it led to a massive issue. And yet again, the school investigated and agreed DS had done nothing to justify this behaviour.
Meanwhile, DS is doing very well at school and has flourished while these other two children are, by all accounts, struggling massively. I trly believe that between their parents and the primary school, they were not set up to succeed and it's still harming them, even as they are now doing GCSEs. Even DS feels sorry for them now.
There is a girl in DD's year who doesn't bother DD at all but I've heard that she can be a real bully to a number of other children, and she's 100% the teachers' pet. She's going to a different high school so we won't see her, but I suspect she'll have the same problem as these boys from DS' year. In part, I can tell because the similarities with the mums is startling.
