No. They just get hi fives from their dad.
A lot depends on how the teacher was acting though, an affair carried on outside of school hours for example would be considered a personal action on their part.
On school grounds or with the person acting in that effect, makes sense. I guess the employer "should have known".
But usually don't these sort of things begin as flirtations on school grounds and then continue "offline" so to speak? I dunno, obviously I'm not a lawyer but it just seems like an absurd amount of onus is placed on employers to thought-police their employees or scrutinize every detail of their behaviour at all times...
