Here’s a conundrum for you: You’re strolling your office and open a vacant office innocently searching for office supplies but alas, you find two workers in a very compromising position.

What to do?

According to Gregory Giangrande, chief HR officer at Time, Inc., in today’s New York Post, letting it go and looking the other way is fine if it seems innocent enough.

He writes, “And if what you observed obviously falls into the category of two co-workers sneaking off to have a little fun, then telling them their secret is safe with you and letting it go is fine.”

That said, if it was something more than that such as an inappropriate canoodling session between a boss and teammate or something that’s not-so-innocent, he points out that “you have an obligation to say something.”
