I’m only looking for relationships that cross hierarchial levels. Just having an affair with a co-worker doesn’t count. neither does having an affair with someone who outranked you, or whom you outranked, if you were in separate departments so neither of you had supervisory authority over the other. On the other hand, if you had an affair with a former boss or subordinate while you were both still employed by the same company, that counts.
I have twice. In the first case, I had left the company and needed to come back for a brief period while I was getting trained for a better job in another field. I had a friend with benefits who had since been promoted into the same job I had left, albeit at a different location. She gave me with the job with the mutual understanding that I’d be leaving as soon as I got the job I really wanted, and we maintained the fuck-buddy relationship in the meanwhile. It worked out well, as she got the services of someone who knew the technical aspects of her job and was perfectly willing to give her help, and yet had no desire to supplant her.
In the second case, after I’d moved into the new job at the new company, I had a boss I thought was quite the hottie. Since I intended to keep this job indefinitely, I kept my thoughts to myself. However, eventually she transferred to another city. Last year while we were in Vegas for a convention, we ran into each other, caught up over drinks–and, well, it was Vegas.
