Well no one else can control how you feel about something. If I give you a terrible load on the preload, it's still on you to get upset. The management and supervisors, the ones we see day to day and not the ones making real decisions, like to think they have control yet they can't and do not themselves have control. If they had control and decision-making ability, you wouldn't see so many drone-like pricks without an ounce of integrity. But that's the model their bosses expect and thus exert that control.
A quick aside, one of the drivers was OUTRAGED at a bad load on Friday. I mean, it wasn't bad, just not to his liking. He was throwing stuff and swearing, etc. Driver B says, with an audience of sups and drivers, and an equally screwed up load and dispatch - "I'm filing an injury report! My feelings are hurt right now and I need medical attention immediately!" It was pretty funny but goes to show how people react differently to adversity.
