My son works at a car dealership (big name) as an entry level mechanic. His is ADD is currently takes medication. He did not disclose to his manager when he was hired. There have been on occasion when he is not in his bay and waiting on parts at the parts counter, or taking a car for a test ride, in the bathroom etc... a lot of little things. Yesterday he forgot to write the space number of where he parked a customer vehicle and he reprimanded him in front of the woman and other customers asking what was wrong with him and did this while at the parts counter asking what was wrong with him and if he has a problem following processes. He went on to say (not in front of the customer)s but in a room with 2 other people in management) do you have some sort of chemical imbalance (very nasty) that you can't follow processes, whats wrong with you.......My son is almost 20, he was almost in tears and said "actually I do and I take medicine for it" he then said I don't give a shit that's not my problem and you better straighten up" the other 2 people in management had to tell this person to stop and just talk normal. My son came home devastated..........As a mother of a son this age, I feel helpless because I cannot get involved. Is this behavior tolerable?
