Thanks, everyone. I spoke with my boss about the Bud situation. She agrees that it appears he is overstepping again. I asked her to let me respond to Bud's e-mails in my own way, and she said she would respect that. I know she is glad I told her about it.
Sadly, we do have some volunteer opportunities that would suit his interests and abilities, but he is no longer interested in pursuing them. I am speculating, but I think with the taste of administration he got before, he now believes that this is his calling with our program. Unfortunately, we don't need administrative volunteers. We have a whole board of directors for that.
My boss suggested telling Bud that some of the suggestions he is making are contrary to decisions that were already made a higher level. That is true in some respects. Some of his other suggestions would need board approval at a minimum. I would be hesitant to tell Bud that his suggestions would need board approval because I don't want to imply that I will be seeking board approval. I don't intend to do that.
I may just stick to thanking him for his time and telling him that we already have plans in hand, which have been approved at a higher level.
