If an accusation of abuse has been brought against a teacher, then that teacher should be put on paid administrative leave until the matter is investigated to protect everyone. Teachers are so vulnerable to being accused of abuse by spiteful students and should be thought to be innocent until proven otherwise.
Fired. If a teacher is abusive, or somewhat perverted towards any students should be fired. A teacher at my old middle school he would look down girls shirts and touch their butts and flirt and he is like 50. All the people know but won't fire him same about another teacher who slapped a kid across the face and he didn't get fired. I find this wrong and sad!!
