Does he fail to accept responsibility for his own actions?
Does he always cook up some excuse? Does he blame others for what he's done? If he's under investigation or on trial for a corporate crime, like deceitful accounting or stock fraud, does he refuse to acknowledge wrongdoing even when the hard evidence is stacked against him?
These questions don't sound a lot like any of the bosses I've had, but they do remind of some Canadian Liberals I know.
