Disability discrimination

I’m having a lot of issues at work and facing dismissal.  This has gone to the most senior level of the organisation, and is what I believe to be a very clear case of closing ranks.  

Has anyone been in this position and what did you do?  I can’t afford a solicitor but am thinking of approaching the no win no fee ones.  My employer has not made reasonable adjustments and has turned a blind eye to blatant bullying comments made by other staff members.  

I have demonstrated I can do the job, and have it in writing (before I disclosed autism) that there are no issues with my ability to do the work.  That has since changed to concerns that I can’t do my job.  And that as a junior member of staff they can’t make reasonable adjustments because that means I would be unable to learn from other people.
