I run my own small business. My general manager has transpired to be a rather tricky character and God help anyone who gets on the wrong side of her. She has very short-term friendships as she always falls out with friends and she holds grudges over the tiniest thing. We are a small team but she has taken a dislike to one of them who was in tears with me today. I also think she doesn't like me. She is disrespectful and rude and very bristly in the office. She's also not great at her job and does the bare minimum even when others need help snd are bending over backwards to help each other out. My worry is if I start issuing formal warnings that things will get worse and she has access to so much sensitive information, expensive product and is the main point of contact for customers and I'm scared of what she could do if she feels spurned. But I don't want her upsetting other staff members and creating such a negative atmosphere and I don't want to feel awkward and on edge in MY office for MY business! But where do I stand? I can't just pay her her notice and ask her to leave, can I? Any advice would be so gratefully received. Thank you. X
