This wouldn’t work because if I met The Rock I’d have no problem openly marveling at his body and throwing in an additional, “and I mean not just that, but AT YOUR AGE, so impressive!” Not doing that with a female coworker.
On the other hand, I have known multiple couples who began as co-workers, dated, married, had children, grew old together, etc. In particular I remember two teachers in my high school who were married and had children. They’d been together so long, and in the same jobs for so long, that by the time I met them, their children had long since graduated from the very high school they met at while they were still young and single. And they were still working there, still together. (And though this isn’t the point, having seen pictures of them from their younger days, they were both quite physically attractive when they were young. For whatever that’s worth.)
If it’s so vital that coworkers never reveal their attraction to each other, how would this happy family have ever gotten started?
Also, what about popular entertainment such as Grey’s Anatomy, entertainment which is based mostly around the idea of coworkers dating? I mean, not every fictional representation in TV/film equates to glorifying, but in this case it does. The fact that these characters date each is not meant to teach the audience that they’re bad people. Rather, fans are expected to like the characters and root for them to get together. For most of its run, the central relationship everyone was rooting for began as a high-ranking surgeon dating an intern. How can we condemn the act of pursuing a coworker romantically in real life, yet not condemn shows which portray that sort of thing as okay?
