Yes, I have expressed concerns about this person privately to him, in a nonjudgmental way. He understands, but is the type to often question repeated issues whether the source is reliable or not. I doubt my job is in jeopardy, though I know his opinion of me has suffered due to a lack of true understanding of the position I've been put in during other tough times. We have cleared up these misunderstandings, but I fear the knee-jerk statements from this other person may have damaged that progress.

Thank you for the link, I will check it out.
