BTW - as a teacher, I think under morality codes for teachers and superintendants, an affair could be seen as a career issue for the latter if any 'indiscretion" was occuring at a school site.
Teachers can be held account for many public realm issues by their Teacher Association. A letter to the school board about an incident where the super was being super to a teacher at a school dance or event where students are present could lead to consequences in my province.
