Well, I got the investigation out of the way. She interviewed several of my employees, the main question being whether I treat everyone the same, regardless of race.
My interview lasted about 20 minutes, and at one point she almost asked if I am a racist. Damn.
It went as I thought it would, the investigation is closed and I think she figured out that the discrimination complaint is groundless.
I am at a meeting right now trying to stay awake, so I have to go.
