I'm not disagreeing with any of the possible impact on the boss's productivity, but rather how a majority of response here are of the kind: "Fire him, be the alpha male! Ouga ouga!" Firing him might be the correct answer; but it's in no way evident.

Try this thought experiment: suppose you have 2 employees. Would you fire one of them if he sleeps with the other's girlfriend, or would you consider this a 'personal matter' and not interfere?

If I am a small business and only have ~50 employees, I would probably fire them. It's only a personal matter until it affects work. This would obviously affect work.

You would fire BOTH of them?

I would ask him to resign, and if he doesn't he'd be fired. Clearly it won't be good for my business to have these 2 working together. The fact that he's clearly showing bad judgement means it's an easy decision as to which one should go.
