I say tell your boss anyway
Is… that guy your friend? is that what you mean?
Because i dont care if he is your friend or not that is not okay.
You have explicitly told him “No” or to stop in whatever way you have stated and he keeps persisting which means he has complete disregard for your request
That isn’t okay. And it is never okay.
There are other coworkers who can help you if you ask, im sure
You shouldn’t sit there and be uncomfortable just because of that reason, my friend ~Admin 404
