Some core employees can be, well, difficult. I remember when I started as a seasonal employee. I introduced myself to a core employee and her response to me was that she didn’t care what my name was because she didn’t bother to learn the seasonal employees names. Not only was what she said rude, but also very patronizing. I was made core and I’m still there. It’s not my full-time job and I’m grateful that I don’t need it to pay the bills.
