I've been working at UPS part-time for about a little over 2 months and i have been unloading everyday with my brother (whos been working there for over a year) until they hired someone just recently to work part-time who they are now putting down by unloading. My supervisor comes down to unload every single day either moving me or my brother down to load, switching off between me and him all the time so the new guy can unload every single day. Me and my brother both hate loading and we get stuff done really fast at unload but whenever this new guy unloads stuff goes slower. My supervisor does not move this new guy down to load at all and it makes me very irritated. Im wondering does my seniority have any play into it because me and my brother both have more seniority than the new guy and i feel as if im being treated unfairly.
