I have a very horrible and difficult meeting tomorrow with a colleague I really do not like. At all. It is very rare that I don't get along with colleagues, but she is a nightmare (and EVERYONE has problems with her). The reason this is difficult is because: 1) She is in a managerial position but useless 2) She is unreliable 3) On this project I am senior to her and she hates that fact (she is the kind of boss who literally stamps her feet and gets hysterical and bullies her staff, but she is not my boss or senior to me, so it frustrates her) 4) She is as stubborn as a mule 5) She blames everybody else for things she has not taken care of herself. I need to get her alongside, otherwise the project will not move on - and I am not having that! I am good at staying calm and on topic (at work ) - but she is like a red flag to a bull for me (had several meetings with her over the years - she is DIFFICULT!) I am trying to avoid saying "Listen, I am Project Manager and you do as I say" (cos that is a thing I would never do) but actually, that is what I need to tell her! as she has not been meeting deadlines, nor communicating with the team. Her line manager approached me today...to wish me luck! (jeeze, thanks for the flowers, babe). What kind of stopping sentences do you use to move the topic back to where it should be and in the direction things should go? NORMAL language doesn't work with her - she also tends to burst into tears or have a tantrum (which makes me want to laugh, but I can't do that, it would make things worse).
