I've been at UPS for about two months now (I work out on the ramp at night) and I've heard that we have to come in on black friday this year. Every year I go out of town with my family for thanksgiving and we always stay to do all the black friday junk so I probably won't be able to make it to work that Thursday or Friday night. Would I be in any kind of trouble if I let my sup. know i won't be able to come in, cause I know this is when peak starts up but I have yet to call in or miss any days. Thanks.
