I may have been, depending how you view this. I was separated, and got involved with a woman who worked for a vendor of my employer. At around the same time, that vendor company pursued me, and I took a job there. So now I was working at the same company as the woman with whom I had this relationship.
I quickly saw she had some emotional issues. I kept them in perspective. As time went on, I reconsidered my marriage. I was upfront with her in this regard. But she clearly was becoming unhinged even though I had made no decision nor spent time with my wife.
One weekend I drove up to visit my daughter at my estranged wife's house. It was a day visit only. When I got there, my wife was livid. The woman had been calling her nonstop in the two hours I was on the road. Threatened her, hangups, called her a slut, etc.
I stayed the afternoon, and drove home. Got back to a phone message (this was before cell phones were too prevalent) from the woman telling me, in no uncertain terms, that if I didn't stay with her, that I could kiss my new job goodbye. She was in management, and would see to it that I would be transferred to her department, and had better knuckle under to anything she wanted.
I took the tape from the answering machine, made two copies, and went to work Monday morning. When she arrived, I put one copy on her desk, along with the written complaint to HR I had drafted. I asked whether she would like me to get my manager in the room for the conversation we were about to have. Amazingly, it still took a few moments for her to realize how stupid she was to put her threat on a recording. The color drained from her face as she realized she had sunk her own ship. I explained that any "me and you" was over, totally, and immediately. I was sending the tape to HR, and it would be their decision how to handle it. I would not request any action as long as she no longer had any interaction with me professionally. She begged me to reconsider sending the tape, apologized, etc.
She was fired 6 months later. I was with the company another 9 years. Given today's environment, her threat could be perceived as sexual harassment in the workplace. Had she not screwed up by leaving it in a recording, I would have been screwed...I had moved 150 miles to a new location where I knew nobody. I'd need to find a new job, move back to where I was, etc. just to get out of a controlling person's grasp.
