Hey, you're free to drop your child off into the Public School unknown for 8hrs a day. That's your call. But Parents need to have other options available. Who are these Teachers? They're complete strangers. Having so much faith they'll do the right thing when it comes to your child, seems to be a pretty frightening gamble. Why take the chance? Probably best to seek alternatives at this point.
True story, I knew a woman personally that everyone loved (I didn't care for her much, she made my skin crawl at the get-go). You know, one of those schmarmy gals that made all the social rounds, rubbing elbows and really putting on a show whenever people were around. She was into being an aide at charter schools. She even pretended to be a teacher once before they found out she didn't have a credential. Turns out the reports started trickling in that kids were being "touched" in inappropriate places by her. Her husband, super crazy & super aggressive makes it so nobody will challenge her legally. So she is still teaching at private schools. Last I heard she's working with the most vulnerable of all, the least able to know enough or to report what is going on: handicapped kids. Everyone who doesn't know her dark side thinks she's a saint..
..At least at public schools there are real and pressing standards, and tons of oversight. Just because you don't know someone, doesn't mean that they haven't been scrutinized and continue to be scrutinized. In fact, an anonymous teacher has a better chance of being fired than some crony that everyone is friends with (and therefore extremely uncomfortable about confronting should any problems arise). I've seen this issue play out more than once. There isn't enough money in the world to make me send a child to a charter or private school..
