This could be outing so I'm being very vague.
I have a medical condition (a lifelong MH condition) of which the specialists have suggested I only work a certain shift pattern to enable me to have decent sleep and take meds at a consistent time-the consultant has written to my employer. They have said they don't think it's possible to put me in this pattern yet they do the same thing for at least two people that I know off. Employed on and off bar a few months for seven years for this company (it's retail) and I have been completely honest with them about this. Where would I stand legally? Can they dismiss me? Thanks
