From boss to co-worker or from employee to co-worker

A colleague of mine at work recently got promoted to serve as a manager from being in a position of somewhat less authority.

I'm obviously not asking about the whole co-worker to boss thing because she was in a position that was higher than my current role with the company but she is now officially in a capacity as a boss now.

I've seen plenty of stories about people who go from being co-workers to being bosses, and how to navigate that particular minefield on both sides. What I haven't seen is stories or advice related to the now-promoted person dealing with people who are her former superiors and are now her co-workers, or from people who were above her in the food chain and she is now their equals.

Any suggestions on how to navigate THAT particular situation? I'm mainly asking because I'm curious, but I also get a sense that it might be something I'll deal with sometime down the road.

 

Upper deck her....
