overworked

Hey everyone! Been with the brown for a few years now and only just found out about this AWESOME place. How cool So I work in a small mountain town hub in the Rockies...6 preloaders, 2 unloaders, 2 scanners and 4 part time sups. Due to how well ups treats their part timers....we turn and burn...

Sorry if this has already been answered here but i looked it up and couldn't find anything. So this whole week I've been loading around 1,100- 1,200 packages during my preload shift(not counting sure post bags, if i did it would be around 1,500), am I able to grieve about this? If so what is...
