days off

Fourth of July is on a Thursday. I work midnight. Thursday is technically my Friday. Is ups closed on the Fourth? I asked a few supervisors and they haven't been at ups long enough to give me an answer.

Hi, so Im pretty excited to start but I had a few questions. I understand that we (part time) dont get payed holidays until a year in, but does that mean we need to work on the observed holidays (Christmas,Thanksgiving etc)? Also am I allowed to request days off? Thank you.
