I’ve seen some with beards. I guess it depends on your location. Every terminal might be different with their own rules. Some might require you to have neatly trimmed beard some not care at all. Just depends on the terminal management. That would have to be an interview question. I have a beard but mine is neatly trimmed and maintained as well every week also. No one ever mentioned anything about my beard. So I didn’t say anything. If you get an interview ask the person interviewing you. But 9 times out of 10 you will be able to have a beard. Pretty relaxed company overs here.
