My initial reaction is to confront the man by all means. And ultimately i would do that regardless of where wifey stands.
However, since it’s a work place thing, who/what is he? A subordinate? A boss? A colleague? It’s important because you want to cause your wife problems with her job.
If he’s a boss, you may be entitled to some money. Get a lawyer first.
If it’s a colleague you still might need a lawyer but, there may not be grounds for a law suit so HR may be her best bet.
If he works for her.....”Lucy, you some splaining to do”
But seriously, protect your wife even if stands where she shouldn’t on the matter.
But yeah, I’d confront him for sure....... unless you sit down when you pee. If you don’t, then get in his face.
