ill treatment

I'm a parent and I'm sick and tired of a new principal who's treating kids as if they are in military school, I think that's even better. School starts at 6:30am and if kids are late by 5minutes he sends them home, what message is he sending to students that time is much more important than their education. Today my child went early and he has decency to send him back home to come with parent, we are working must we stop what we're doing f his incompetence. New principal needs to be appointed because none of the parents will stand for this and worse he is arrogant and rude
