I have known managers that would scream in your face two inches from your nose.
I have known a manager that pulled a driver into the office to yell at him to the point of tears, all the while knowing the driver's wife was in critical condition.
I knew a manager that told a driver to dump a leaking Haz-Mat (prohibited in or system) down the sewer.
I knew managers who forced a driver to work knowing he was being sent into battle (desert storm) at Midnight, while they stayed in the office.
I knew managers that would say they were going to try to fire you simply because you averaged a few tenths over.
I know managers that would outright lie in disciplinary hearings to try to build a stronger case.
These were the ones who were promoted.
Not all of us work in the BOG.
