representation for autistic daughter in work disciplinary?

Hi, i was hoping if someone could point me in the right direction of somebody to speak to in regards of a disciplinary hearing my autistic daughter has at her workplace. I feel like she should be able to have someone with her due to her disability, in what would be a very stressful and overwhelming situation for people without autism, she works in a school and has been told no on else can speak for her, i don't think this gives her a fair crack at the whip, it does not seem like they are taking her autism into account here at all. thanks in advance for any help you could offer me.
