Hello, posting regarding a friend who works at a corporate firm. Her line manager was very angry with her over an minor incident and called her the c word in the office in front of a witness and that witness reported it to HR. There have been previous complaints of his rude/shouting behaviour in the past but not formally or via HR. My friend is protecting him worried she will be responsible for the demise of his career. Is this a sackable offence? He is so toxic and I want her to be rid of him but she is beside herself.
