I've had migraines since I was 4 years old and I'm on daily medication which helps but hasn't stopped them completely, this has been classed as a disability, my employer put me on a sickness review, I was recently off with a sinus and chest infection as with the migraines it has left me having 1.25 days off more than they allowed, they have now set a disciplinary hearing with a view to disciplinary action, I don't know what to do, my migraines are often triggered by stress, should I contact a solicitor, can anyone help me with what to do next please?
