I need some help, I work with a very good friend and have been friends for almost 10 years. She has some mental health issues and I have been there for her as best I can. Lately she has made it impossible to work on some days, she is constantly up and stirring the pot to different employees and never completes her work on time. I work for the owners, high stress and high responsibility. She gets away with murder, calls out sick all the time, vacation, talks very loud and gets everyone upset. I need to figure out a way to nicely tell her she is out of control in the work environment (considering her managers wont!!) I hate being in this position, I did go to her before about this and she wasnt too nice, and blew off coming to my wedding. I have since distanced myself as best I could without a big confrontation, I am not confrontational at all... Most of the time things are fine, but there are days I want to run out of here screaming, going to managment DOES NOT DO A THING.... any suggestions???
