I work in retail but I cope 99% of the time, but I’ve got friends who stutter who are delivery drivers, hgv drivers, the person to person interaction is very minimal and they have no problems at all. It’s a difficult one because from what I can think of there’s not many jobs out there that don’t require you to speak to customers, use the phone, stand up and give presentations etc. Try something like Amazon delivery maybe? Or factory/warehouse work? Postal work. Kitchen work. I’m sure people will have suggestions than me, good luck anyway!
