Nepotism - Sales DataRobot Employee Review

When we were told 'earn your seat' I took this to mean: perform well and one will be rewarded. I did not think this meant hiding your friends and former colleagues underperformance. Letting go of someone who was performing, but not 'drinking the cool aid' is understandable. However, how do we then have people who have not closed any revenue in the trailing calendar year? These type of inconsistencies are creating distrust in our leadership. The arrogance is causing underperformance, without any course correction.
