Pros
Good benefits. guarantee of 27 hours work a week at minimum. Very physical work, so you will stay in shape. Very task oriented work, have to know how to juggle problems and make good, quick decisions.
Cons
You get blamed for everything, regardless of how well you do your job, makes it hard to try and go above and beyond your duties when you arent recognized for it. I.E. getting done early, filling out all your paper work on time, getting more scan checks than required. Constantly harassed by both upper management and drivers/loaders for every little mistake; even if its not your fault. An air goes missing, a package breaks open and spills, or a loader goes over his max time because he wants to help are all things you will be blamed for making it hard to stay motivated to your job and help your team of loaders stay focused and get done.
