I think I was more nervous than when he originally interviewed me for the job i currently hold. But I had taken some time at my desk before hand to consider and structure my thoughts.
I told him all about my own personal disappointment over not been able to do the coaching training through work and how I was going to fund the course myself.
He said some very supportive stuff, confirmed that he had no issues but would check out the form filling side with personnel. He also approached them to see if they would help fund my learning. I didn't think so and I don't think he did either but I appreciated that he gave it a try.
I think he was actually relieved as he may have thought I was building up to telling him I wanted to leave.
He did get an agreement from personnel that if I needed some practice coachees that I could do that in works time - how fab a boss is that.
