We have a woman at work whom I line manage and she has been hinting heavily about an upcoming promotion. I've known her for years and know her home life is challenging. She believes she deserves it because of seniority. The problem is if I'm being objective, and I have interviewed many candidates for the same role as her, she lacks the skills, agility to get the job done, and she is not a good team player either. She also gets angry quite easily to the point of almost getting herself fired. My boss is considering not to give her the promotion, but a part of me feels sad for her because she always says she is skint and needs the 5k increase. She is well paid at 50k+. I think she will leave if she doesnt get it, which doesnt affect the business if I'm being honest. I'm not sure how to break it to her that she is not getting it without her flying into a rage and she always says she needs money for her demanding DP and 3 DCs. My head knows for a fact she doesnt deserve it, maybe I'm just afraid of her reaction and the guilt knowing her home situation?
