AIBU to refuse to work with someone? The said lady has a very demeaning, abrasive manner. Nearly every comment she makes is a complaint, and she literally flies off the handle for the smallest of things. Yesterday I warned her a very urgent task came up for me, and I will not be able to attend one of her meetings, but my manager will dial in instead. She flipped, swore and wrote a complaint to a C-level exec. I've been with the company for 6 years and have a clean record, literally zero conflicts with any employee, we've managed to keep it civil and friendly even at the hardest of times. What I hate the most is that I come in to my children, and bring this energy with me - beaten down, negative and tired. Obvs I've raised with my manager, but are there any other steps I could take?
