I worked at a place where to plug something in (computer, lamp, etc) you were supposed to call an electrician. To move a chair from one cubicle to the next you were supposed to call a mover.
They don't do that anymore, as most people ignored these rules.
I'm an engineer. I can't carry a part from one lab to another. Must have a hourly paid union member do that. If I'm caught and they file a greivance, the company has to pay them 1 hour of my salary, then I get chewed out by management. Most of the hourly staff don't care, but there are a few that are hell bent on doing as little work as possible and looking any excuse file to a greivance.
