Go to your directory find your SD go to each AD that reports to them copy them all onto a spreadsheet including the managers since their on the chopping block too. Riff at least 20% from that list after rack and stack everyone if you fall into the bottom 20% then you know the answer.
I did that last Friday and I'm good too go for now.
My 20% was about 16 people across 5-6 managers
Do with that what you will
