My boss and my co-worker have had the very public appearance of a very private relationship for over a year now. I actually had to change cubes to get out of the line of fire as I got tired of all the cutesy sexual innuendo chat. Then last year, heard through the grapevine that the rumor was they WERE knocking boots. And to make it better, my co-workers husband sits about 40 feet away in another cube. I did the "proper" thing last year and informed my boss of the affair rumors thinking he was just being a ******* flirting with my co-worker and he'd check himself for professional office behavior. Their shenanigans continued and got worse (as did the rumor mill) until earlier this year when I approached one of my corporate coaches about how I should approach the situation. That was when I found out my co-worker and my friend about 40 feet away were getting divorced. So the company does an "investigation" and tells me that there was no "affair" to which I say "I don't care" since their antics have created an amazing rift and tension throughout our floor. THEN my friend getting divorced tells me about pages and pages of sex texts between my boss and my co-worker which the company does NOT know about. I've already been told by an executive to let it go even though my boss and my coworker are still both in my department. Other than the tricky legal ramifications of dropping the sexts on my VPs desk, should I just be a good boy and toe the line and just pretend that nothing has happened even though everyone laughs at these guys, and the office environment is toxic?
