im still working my way through this thread but up to yet all i can think is this guy must be like moss from the IT crowd!
Dear god man, its 10-15kg boxes, thats nothing, most people use that weight in dumbells with one hand and your complaining about using 2 hands!
If you worked for me id be looking of a way to make you redundant which shouldnt be hard as theres no work for you.
The place is a team, you help everyone because when you need help they will help you and you wonder why its a dead end job for you when theres no effort put on your part.
Pushing pencils around......dear god!! Now i see why the guys in the warehouse laugh at you, put some effort in and you will gain their respect
You'd be surprised at the amount of people who appear rather muscular that struggle with 10KG+. I've lost count of them now, but I refer to them as "dignity weights"

Hopefully your excuse is that you've just started.
