This actually happened at my last job (so at least four years ago now, since it was in the pre-pandemic days). I started drafting this a few years ago, but I abandoned it because I didn't want to get in trouble if my boss saw it. But I haven't worked at that job in almost two and a half years now, so I finally pulled it out of my drafts, finished it up, and posted it.
But yeah, we had one especially fractious discussion that inspired this post (though many other discussions were at least a little frustrating or contentious). Many of the lines are direct or near-direct quotes. And I'm probably safe pointing out here that the coworker in question was literally named Karen.
