She started 7 months ago and had been acting like she's the manager by telling us, who have been there years, what needs doing and trying to get us to do her work for her. We work in a health setting. A surgery and patients come in and out. She's constantly butting in peoples conversations trying to join in and she sits at the desk where patients are and puts eye drops in and eats her food in front of everyone instead of waiting for her break. She has also annoyed other people at work about these things too.
She once muttered under her breath "well i won't talk to you anymore then" when i asked if she was still enjoying her job because she kept moaning. And she also turned off the heater she knew i was using when she asked me to do something again but i said calmly, " just do it when you're not busy".
Anyway i was fed up i hated her trying to talk about my personal life with her. i tried answering calls when she tried to talk about stuff other than work and that failed so i said i prefer to only communicate when it's related to work. She went straight to the manager to complain about me! now i have to go into work not knowing what the atmosphere will be like
