OP, I would write this. I hope it helps:
"[Name of head], just to follow on this, and re-reading your email, I am shocked that you are unable to see the gravity of the situation. Please clarify how a child that has been bullied will have a great time whilst being in close encounters with the very person that has bullied her? This trip is for enjoyment, not for a child to feel terrified and anxious.
I understand that there were different teachers last year, and that all new staff may not be aware of the situation, but you have full knowledge of everything that our daughter went through. You are fully aware that she is suffering with depression, anxiety and thoughts of suicide. Whilst she may do her best to keep on appearances in school, she is still struggling internally.
Since finding out that she will be sharing a room with [bully], her anxiety has worsened and she is in a state of fear. Please clarify to me how you in the position that you are, and the duty of care you have for the children can justify this decision at all? We as her parents will not allow this, and we are failing to understand your acceptance of the situation.
The school is neglecting our daughter's welfare by not taking this matter seriously. If you insist on not changing her we will have no option but to take our appeal further to the next stage. This will include a complaint to the governors, our local authority and Ofsted. I am sure they will understand that there is a failure of safe guarding a vulnerable child here and will act appropriately.
In order to resolve this situation we are requesting:
-
That she is not put in the same bedroom as [bully] or in the same activity group during the school journey.
-
That all adults on the trip are informed of the situation so that they can keep an eye on things to ensure the well-being of our daughter.
Should you still refuse to reconsider, other than taking this up with the relevant authorities, I will be excluding my daughter from the trip and will request a full refund.
I sincerely hope that you do reconsider and act in accordingly.
I am happy to discuss this with you further and also with the staff that will be attending the trip.
I look forward to your response.
With regards,
