Working in small sort for over a year now, I’m not a bad worker I’m not the fastest but I’m not letting the belt stop and I’m doing what needs to be done. I show up I do my job and I go home. I show up to my section and start working, the belt has stopped from being jammed multiple times but not from my side I notice the Ft sup kind of off to the side glaring at me, I ignore it and then he start walking down the SS lane yelling about “we need to pick up the pace you guys are sleeping if you’re not ready to work go home” after 10 minutes of that he comes up to me and says “what’s wrong with you that’s making you incapable of working faster then slow” I told him ”I feel like I am working at a moderate pace” he says “no you’re not how do you like small sort because how you’re going we might get you over to outbound where you can drag ass over there” at this point I realize he’s just angry and needs someone to intimidate so I keep moving to tend to the bags. He’s literally following me trying to be a bully over how I work. “Why are you not closing the bags at this level, who trained you, maybe you need to be trained again” he’s in my way and I need to go around him so I just said “excuse Me” and he goes “no you will look me in my face and listen” after a minute of me not responding he says “either you do your job faster or I will send you to another position or better yet don’t come back” I feel like him being so excessive wasn’t necessary and can a sup even force you to move out of a position??? I felt like a grievance might be something I could do but is it worth it?
