Hi Rachel,
You say this is a person who has never been a supervisor before, and you’ve never worked with her. Did she work in another area before, or did you know her at least a little? Did she receive any “how to be a supervisor” training. She’s probably scared “shi*less” that she won’t be enough of a leader, and is overcompensating.
But, knowing the reason doesn’t help you any, does it?
Perhaps you could schedule some time together so that you two can get to know one another a little better – maybe ask her to have lunch with her so you two can get to know each other. And if you go “out” and leave the workplace, it can be more casual.
Start out by asking about HER. If she came from a different “work group” who did different things, ask her questions about how long she’s worked in the same place, ask her what her job responsibilities were before. Ask her how she’s getting “used to” working with new people, and possibly in a “new area.”
This way she almost HAS to ask about you. That would open the door for you to discuss your past accomplishments. Acknowledge that you both have to adjust to working with different people, and you’re more than willing to “help her” out in any way you can. Let her know what you worked on before – she has NO WAY of knowing your specific skills. Talk about the things you worked on that you think brought out the best in you. Don’t talk about it in the light of what she’s doing wrong, or how she can better do her job.
And be careful of going over her head too many times. She just might perceive that the 2 of you “conspiring” against her. And, if you talk too much to anyone about how the changes aren’t working for you, it can appear you can’t be adjustable in the work place and learn to take change as it comes. There’s only thing you can be sure about – that there will always be changes.
You don’t need to become best friends to have a good working relationship; but you do need mutual respect.
But maybe one or two of these ideas can help. I’ve never worked in a school environment, but i’ve had a lot of experience in working in large financial institutions and have had to learn how to make the “politics” game work for me. I’m considered a "very experienced non-manager, and want to keep it that way.
Once again, writing too much,
peace,
c.
