I once saw a manager, who was an absolute witch to most but had her favourites, get walloped in the face by a colleague. By all accounts the manager had just tried it on with the colleague, who was not interested in women.
The colleague remained with the company and is still there as far as I know. The manager left quietly.
I had a similar experience to DanceLikeFredAstaire’s above with a line manager who disliked me and I couldn’t understand why. She worked in the same room as me and wouldn’t talk to me. She was just a vile person and on one occasion she’s been screaming her head off at the other person she line managed in the corridor outside and vice versa. We all heard it. I only worked there for 4 months and had never felt so unwelcome.
All communication unless I went and spoke to her was by email. This proved to be how she came unstuck. She emailed me and asked me to look into options for off the shelf drug and alcohol testing of all things. I did this, sent back numerous examples of kits - costs, how they worked, how accurate they claimed they were etc. Thought nothing of it.
About a week later I was asked to go into her manager’s office and my manager was already sat there. The manager’s manager started laying into me, “this idea you’ve had about off the shelf drug testing,” and how terrible it was.
I had my phone with me and while she was rambling at me, clearly getting annoyed because I was using my phone as she ranted at me, I forwarded the email I’d had from my manager, which showed exactly whose idea it was.
I said, “go and check your inbox. I’ve just forwarded you the email so you can see for yourself who really deserves the credit and the rant about how stupid the idea is. It wasn’t mine.”
My manager was looking horrified at this point, realising what I’d done, and I just laughed. She lost her cool and said I was mocking her. I replied, “indeed, so what are you gonna do?“ With that she started stuttering and said, “I’ve got to go,” got up and walked out of the office. Her manager looked gobsmacked and started talking at me.
I said, “I’m not interested. You know fully well the sort of person she is and you’ve done nothing about it for years, so you’re an enabler. Wish the next person good luck from me because I’m going to leave now.” I went and collected my stuff and walked out.
Only job I’ve ever gone AWOL to this day. They’d struggled to recruit for the job for months before I’d accepted it and I was still seeing it being re-advertised 5 months after I left.
