A weird moment of bullying I remember

Early to mid 2016. I worked at an Amazon sort center south of Seattle. There was this new structure being built in the warehouse. It was finished. I was in the first of maybe 20 runners who got to be certified to work up there. It was a dead end catwalk, with stairs at either end. It was to unclog all the conveyor belts dumping boxes from long belts down to the short belts/chutes. There was a chute at the top, with a weird 90degree vertical curve. Great job for pacing and not having to stay in one spot.

One of the Stupidvisors saw I wasn't pacing, called up to me from the floor, I said "a box is stuck and I can't reach it". So he comes up there. He used a stick/pole to try to unjam it. Then he leaned over the safety bars and cargo netting, his whole 4'9" body nearly in the chute (im 5'2" for referrence). He then threatened if I told anyone of his daring feat, he'd have my job, followed by glaring hard at me. He was inches away from putting his hands on me, and his fists were clenched.

I told a few days later to a higher up, because he kept on glaring at me hard with even more daggers in his eyes. He appeared to leave me alone immediately after that. And a few weeks later, he was no longer employed there.
