Since you asked
Right at the end of the day I got an invitation to complete an evaluation of my boss’ coaching skills. He provided my name as someone who could give input for some online evaluation.
Earlier in the day I had talked with him about some of our recent interactions that frustrated me. I did it when I was not currently being frustrated and I think I was pretty able to express the root of my concern without drowning it in pure vexation. Indeed perhaps I was too temperate, since later he gave my name to evaluate his coaching skills. Nearly all of my answers landed on the wrong side of the scale.
The survey was completely anonymous, of course, so I suppose I should be working on my resume now.
