I was wondering if you ever work with people that have difficulities in the workplace that has to do with their disability. More specifically, I ask if there were any disability act for persons with severe profound hearing loss in the workplace being late to work due to not waking up to her vibrating alarm clock. She lives alone and cannot hear a regular alarm clock. She is put on probation for using so many personal hours due to being late because she did not wake up to the vibrating alarm clock. Thank you
