These threads come up every so often and are always ridiculous - and this is one of the worst yet. Half-cracked nonsense about ‘burner phones’, drafting in male friends to make anonymous calls and demanding pay-offs in return for silence… you’ve all been watching too many ITV dramas. And drama is the key word here. How many posters here think this would genuinely be a good thing for the boss’s wife, rather than just enjoying the idea of something so juicy going on in their workplace?
Even if you leave the supposed moral dilemma aside for the moment, there are practical considerations here. What happens if the wife gets a call where ‘unknown number’ or a number she doesn’t recognise flashes up and she rolls her eyes, thinks ‘bloody cold callers’ and presses cancel? Or if the email goes to spam and is never seen? You can’t be sure she’ll ever even get this anonymous message.
Even if she does, unless she already suspects her husband, her first thought is likely to prank/poison pen. Wouldn’t you think that if you trusted your partner? She might not even confront her husband - and even if she does, if he’s lied well enough so far to cover up an affair, he’s hardly likely to crumble under the pressure now. Even if the wife doesn’t assume it’s malicious, he’ll soon try to convince her it is - and again, unless there’s already a lack of trust, she’s likely to believe him over an anonymous letter or call.
All those crying ‘But she deserves to know!!!’ seem to assume the OP will be believed. Why? Would you? Even if the OP didn’t go down the anonymous route, the wife’s options are believe her own husband, or a woman he works with who she barely knows. And what can the OP tell her? Someone else saw them in ‘a passionate embrace’ - pretty easy for the boss to call bullshit on that, or at least claim it was misinterpreted. The OP actually has zero in the way of hard evidence.
In a nutshell, the OP has two choices. One is to go to great lengths to anonymously inform a woman she barely knows of a suspicion she harbours (and it IS on a suspicion, even if it’s likely to be a correct one), with no way of knowing if the message will even reach her, if it will be even vaguely taken seriously if it does, and which could still be traced back to her given that she’s already quizzed the boss about it. Two is to, as the very first response in the thread said, keep her beak out.
I know which I’d pick.
