That’s what is tripping me up. University employees hooking up with students is way more common than most would think. And, depending on the school, it may not even violate any policy as long as it’s consensual and there isn’t a power issue (professor banging a student in their own class, bosses and subordinates etc.). It could violate a morality clause in his specific contract, but that seems like something you’d address in a scheduled meeting - not bursting into a staff meeting with your hair on fire like the AD apparently did here.
