hello, i'm a part time employee at UPS. I work in preload and sometimes at local sort. i've been working for seven years now. last night my immediate supervisor told me I had to cut my hair and that I needed to shave, too. and then my center supervisor told me the same thing. on the seven years working I've always been able to have my hair or beard as I would want, since I never work to attend customers or as a driver or nothing, i just handle packages. now, my question is: are part time employees, working inside the center, "with no contact with the outside world," required to shave or cut their hair? and what should I do next time my sup tells me to shave or cut my hair? thanks a lot.
