Is termination possible?

We took a flight and we have a carry on pet (small dog). I was not aware of pet carry on policy such as not holding the dogs carrier or having his head poke out of the carrier. We were very rudely told by the flight attendant that we should know the rules and that my spouse (delta ramp agent) should know the procedures for in flight rules. We put the dog into the carrier and put the carrier under the seat as soon as we were notified and didnt make any fuss. Could this result in termination for my spouse or loss of flight benefits?
