In the last building I worked in, that's the air drivers job. Shuttle around ground misloads. the safety committee union rat didn't do squat, not even misloads
Just sat in the A/C office and blabbed all day. Sad!
P.S little story summerized.
About 3-4 years ago, I was sorting on the "sort aisle" - there were 2 guys unloading and me sorting. Because of a jam on a sort belt, I moved laterally to break a jam that was behind me.
Moving out of my work area by 3 feet, to unjar the boxes, A 50 pound tube rolled off the belt and fell onto my leg (overflow above all the other boxes from the other side) Of course, it was the enourmous flow that caused this to happen, yet management claimed it was my fault for being out of position! and this was posted into my record, and I eventually took on more problems and harrassment because I did report the injury at the time.
That was very very painful and I was not going to leave without reporting it.
Saftey at UPS? Does not exist - until work is performed at a reasonable pace, and you put yourself in positions where you cannot possibly be injured for any reason. The above references a good example of doing too much (apparently, in UPS's eyes) to not distrupt the operations.
