In the days before smart phones I had a former co-worker who was in a similar situation to the OP's wife, and was frustrated that her complaints were being ignored. She got an appt. with the big boss and HR, waltzed right in with a micro cassette recorder, turned it on and plopped it on the boss's desk. She said, "This is for all our protection and to make sure there are no more misunderstandings." She ended up getting fired (low performance was official reason), but was sent off with a very comfortable severance.
