Right to work
Nobody has the right to deny you a job because of your epilepsy. People are only allowed to deny you a job if your epilepsy causes risks in their performance of your job, and there is nothing they can do to make it possible for you to do the work (what the law calls reasonable accommodation). For example, the owner of a matatu or taxi can deny you a job as a driver because of the chance that you get a seizure while you drive. However, they cannot deny you a job as a receptionist because you have epilepsy: epilepsy does not hinder you from answering phones or receiving visitors.
