i have recently had 2 seizures (even though i am on medication) which i know is due to work stress as my biggest triggers are stress and lack of sleep. my employer cut my hours which will now put me in financial difficulty when they were not meant to be allowed to and then tried to change my shift patterns to which i said no as had other people yet my shift was changed on the rota ( luckily when i explained no again the issue seemed to be dropped) i had informed a manager i was very stressed and that could trigger a seizure yet no adjustments were made and no offer of support was made. my manager seems very keen to get rid of me and after being signed off this week by a doctor after my seizure i am concerned when i return to work my employer is going to try ad dismiss me. is this allowed? i also realized my employer has never asked me about my epilepsy or done a risk assessment or even asked what to do in the event of a seizure could i complain to the union about this?
