Imagine you are the VP of a department and you put your workers in the best position possible to succeed but they keep screwing up super basic things they should have learned in high school or college.
However, you can’t fire them due to their contract, the people that would be their replacements screw up in the same ways or worse, and you can’t hire new ones, that may or may not be better, for a whole year.
You don’t personally train most of these people either. They have other managers to do that, ones that that you have had no hand in hiring.
Also, your company has basically no money, so you can’t hire top of the line employees either. You have to make due with what you can afford.
That’s the comparison.
