Rudeness, safety and knowledge sharing

So, who are there believes that it would be easy and effective to do knowledge audits, knowledge interviews, assessments or a basic reference interview with a "difficult" colleague? Certainly this represents a situation that many of us have dealt with. Expert opinion, field experience, and organizational guidelines suggest that rudeness and disruptive behavior are worth considering as they present barriers to safe, effective healthcare. Are librarians, info pros and others dealing with knowledge sharing being affected by this state of affairs? Do they in turn intimidate and belittle staff around them who may come to the library or training sessions? Are we talking about this as an element of our role in safe care? Should we be?
