I need help with preparing for a disciplinary

I have a disciplinary against me on bullying and harassment grounds for supporting students in their grievances against a staff. I have documents for the management case, my own summary of defence and many witness accounts and supportive evidence. I need someone to read through it all and offer advice. I believe I'm being victimised. Need expertise in whistleblowing, equality, bullying and harassment, and data protection. UK based advisers only.
