UPS and FED EX are both rather easy jobs, but physically and mentally, the shit will drive you nuts. I use to work for ups for about 3 yrs. Ups has the better benefits package, but fedex will give you more money because they have no benefits. During the whole dot com era there was tons of room for advancement, but nowadays I hear its hard to move anywhere. I just got tired of the same ol shit everyday, lift sort un/load, keeping the missorts out of the trailer. Then if you do a good enough job and keep your shit on pace, or ahead of the rest of the workers, youre rewarded with more work.
good luck player. it aint a job for the weak. all the shifts suck, and you punch out covered in dust n dirt, exhausted and probably mad as hell.
