Pudmuddle, I would first set up a meeting w/her to discuss the action plan and what her expectations are. Listen to what she has to say and jot down notes. Maintain eye contact at all times, sit up straight, and be as calm as you can be. Once she is finished, then address the items she mentioned one by one (from your notes). Ask her to give you examples, especially when it comes to working with your team.
Yes, her little behind has been stung and she's not happy. She doesn't like having emails posted to her w/questions, clarification and follow ups. She feels threatened because she can't remember what she's asked for on any given day. Keep in mind, she's new and she's really not advised you of what her expectations truly are.
Sit quietly, the answers will reveal themselves when you least expect them to. The past is gone, the present is a gift and you need to focus on today, allow the future to reveal itself when it is ready.
