What about reciprocity? The teachers should be allowed to have sex with the students five times before they get in trouble.
/Sarcasm
Is that five times with EACH student, or five times overall?
And cheat 5 times before they fail the class.
This can't end well. Imagine snotty jr high kids taking turns tormenting the substitutes with the 5x's rule. And they're helpless to defend themselves or punish the kids. One teacher I had in HS had a very quiet voice and was tormented mercilessly by some kids. He threw a chair. They were suspended. He retired at the end of the year, years ahead of schedule. And that was at a time not so many years ago when one could punish a student and parents didn't defend their students misbehaviors.
And, oh, some are doing that now!
