Hi Group

I believe i have suffered disability discrimination at work, resulting in dismissal from a large employer.
As a worker (rather than a full blown employee) do i have a Legal right to the employer's internal Appeals process?

The employer said I could appeal and i did, but 6.5 months on my Appeal still has not happened.
I was "promised" on many occasions my Appeal would happen soon.

I have lodged a claim with the employment tribunal.
