I agree with cbg that employer cannot be required to let you work if unsafe to do so...or hire others to provide for your safety and that of others around you.......but if there are some possible minor shifts in duties ......that keep,everyone safe...might make sense to address same....and Id,seek,some help from an epilepsy rights advocacy group PRONTO as well as a lawyer skilled at ADA issues..Mynview is it's often easier to modify something before a supposedly final decision gets made against your point of view. you may well not have good odds but some odds beat those of doing nothing.
