Today was my second day at a warehouse. I have never worked in a job like this before. I am in charge of boxing and labeling car parts. Towards the end of my shift, the manager came over to me and ripped all the stickers I was about to use out of my hands super aggressively and said I was doing it all wrong. He then (after ripping one of them in half) put them up almost the same exact way I was. A bit later that day a person was trying to reload a nail gun and he did the same exact thing to them. Is this normal behavior in warehouse environments? I thought about quitting, but I really need the money. Am I just being a wuss?
