From JNJ: go to HR, where your wife works, and tell them, he is hitting on multiple women, at work, and trying to break up their mge,s---they will deal with this cuz, what he is doing will mess up the work environment---and could cause them to lose good employees, such as what you are being forced to suggest to your wife, and possibly be involved in law suits if THEY do nothing.

This is some leverage to get the other man to leave the job instead of your wife having to leave. Most companies have an extreme, almost irrational fear of lawsuits, even unfounded ones, and will take decisive actions to correct situations potentially giving rise to them.
