Timothy, thanks for sharing your story here. I think managers and HR folks need to reflect on what you've said. Even if an idea person is stepping on toes by pushing too hard, what is the correct response? To apply labels like "disobedient" and "insubordinate" (or "unfocused" and "undisciplined")? Or to engage in self-reflection and ask, "Why is this person getting under my skin? Do I need to be more open? Am I being intolerant, because this person is so different from me? Can our company benefit from this person's thinking--and I just need to help this individual find a more effective way to package and present new ideas in our organizational culture? It's sad and expensive when employers lose idea leaders in the manner you described.
