He treats me like an adult. I come and go as I please because he knows my work is important to me and I won't miss a due date. If he needs me to be in the office at 9:00 AM, he mentions it the afternoon before, and always with humor.
He respects my opinion, and brings me into his confidence on some management issues. He encourages me to defend my work and his critiques are always about the project at hand -- he is confident about his power and position so he never feels he has remind me who's boss.
Do I get annoyed with him? Yes. Of course. We're both human and we work in a high-pressure industry. Plus, let's not forget, he IS my boss. But, if things go as badly for this agency in the fourth quarter as some have predicted, I can't think of anyone (except maybe Don Draper) I'd rather have let me go.
