In my hub every supervisor I've had over the years will break jams, load, unload, sweep, etc. This also includes all the full time supervisors. They do this everyday. They will also send people home or to another area and because of that they will have to pick up some of the work; irregs/loading. They will also walk on chutes, throw/toss boxes, walk on rollers, stack packages, walk on running belts, not use load stands everyday as well. The only time they want me to follow the methods is when we are being audited, a bigwig is there, a trainer or safety committee member is doing an observation on you. Or if they need to take a picture of your wall. But after that they will tell you to forget the methods and tell you to hurry up. Just go as fast as you can and toss everything. So in turn the employee culture in the building is to also toss all the packages and not use the load stands. In the building no one has ever filed a grievance for this and it's quite normal. It seems most of the people on this forum would file a grievance. But I'm not even sure if my local even cares to enforce this. In my hub it seems like this would be a backstab and just put a target on my back.
