Re: Running them ragged
No, that's a C-suite thing. Ultimately they set the performance standards, and the manning requirements, without looking at the two together. Lower level management is tasked with meeting those standards, and will themselves be written up/fired if their people don't meet the requirements. Management isn't the enemy so much as they're caught in the middle, and their performance reviews are based on the performance of the people under them.
One of the reasons I like my peon position and will never work another management gig.
