I get around 400 pph. But my sup still yells at me for not going faster. Yesterday, we had a really huge jam in unload and it hit me really hard and I simply couldn't deal with it. My sup came in and said "you have no idea what's going on do you? Snap out of it. You have no clue do you?". He broke my jams and yelled "GO! Pick it up! You suck today!" I always get upset with him for saying this but I usually just nod in acknowledgement. Today he did the same thing. I was going at over 400 pph but he came in again telling me I was going too slow. I was really busting my ass. As usual the end of the trailer had egress issues with packages falling off and building up. So my sup comes in again today while I was trashed and tells me he'll powerload for me. Well he started power loading, while yelling about how the packages wouldn't fit. And he started complaining about my egress and said that it should be completely clean and he started freaking out and screaming really loud and said "THIS IS COMPLETELY UNACCEPTABLE, I HAVE NO PLACE TO MOVE BECAUSE OF THIS REALLY MESSY EGRESS". I told him that it's something I have to deal with all the time and that the packages were out of my reach when they fell off. He said I should have picked them up at the start of the day when the flow was lighter. But I said that the packages didn't fall off the belt at the start of the day, but much later. At the end of the day he always yells at me to "MOVE" and get the irregs in as quickly as possible. Even though I'm already moving quickly. It just makes me upset because his yelling doesn't actually affect my speed and his rude behaviour is demoralizing. All the other employees hate him and have confronted him. He has personally told me he's trying to get one of them fired. He tries to write them up all the time or report them to the full time. I guess I'm his favorite since I never talk back. But another sup told me he makes fun of me behind my back. I have never confronted him because I don't want him to write me up out of spite Anyway, I was angry at him but I always try to remain as calm as possible. I asked another sup on how to deal with him and he said "don't worry about him, he's always crying on the radio, he's not from the area so how would he know? next time he gives you trouble tell him "how would you know?". I told him that I couldn't say something like that because it's too rude.
