Should I tell my daughter?

This morning my husband woke up sick ( fever, white spots in his throat, etc...) and called out of work. According to our daughter's rules, he must ask her first if he is allowed to miss work ( he didn't ask). At 7am, she came down to breakfast and asked where he was. I explained how sick he was and how he called out of work. My perfect princess was furious!!! She stormed into our bedroom and began screaming at him. My husband was about to explain that he was sick, when she punched him in his private area then slapped him across the face. He wimpered and moaned in pain, but got up for work. Here is the problem, after our perfect princess corrects us, we must thank her for doing so, and he didn't!!! She didn't seem to notice that this morning. Should I tell her when I pick her up from school today? I know she would think more highly of me if I did. I also know that my husband will receive an additional punishment for not thanking her.
