Wow the absolute trolls displaying hate towards children with SEND on this thread. I don't know what kind of 'phobic' that is but it's what proper bigotry looks like.
Children are not there to validate adults who are paid to look after them and teach them.
This TA is failing the absolute basic first level of care and safeguarding responsibility - to not place their needs above those of the the child and to not make the child feel scared. The OPs child is sufficiently fearful - after ONE DAY - that they no longer want any very hard fought for 1 to 1 time. Essentially denying their access to education because a man has made them scared.
That's a pretty serious safeguarding failure right there.
And, whilst we're talking safeguarding, here's the definition of emotional abuse in KCSIE 2022, which all school staff should have been trained on (bolding is mine).
"28. Emotional abuse: the persistent emotional maltreatment of a child such as to
cause severe and adverse effects on the child’s emotional development. It may involve
conveying to a child that they are worthless or unloved, inadequate, or valued only
insofar as they meet the needs of another person. It may include not giving the child
opportunities to express their views, deliberately silencing them or ‘making fun’ of what
they say or how they communicate. It may feature age or developmentally inappropriate expectations being imposed on children. These may include interactions that are beyond
a child’s developmental capability as well as overprotection and limitation of exploration
and learning or preventing the child from participating in normal social interaction."
I personally think forcing a child every day to use wrong sex pronouns that they struggle with and which cause them cognitive dissonance, communication difficulties and distress constitutes emotional abuse.
And to those saying 'oh this is all part of life'. The fact is, most people used sex-based pronouns and forms of address. For neurodiverse people or those for whom English is not a first language, menopausal women with brain fog and many others, they simply will not be able to deal with changing the entire rules of grammar and everything they've ever learned about English grammar so that pronouns are individual rather than referring to one of two sex classes. So trans people do need to get used to that in the workplace. No-one means any harm, it's just their lived experience is that pronouns are sex-based not gender based. Anyone with a modicum of respect for the needs of others will accept that.
