Rant about my kid's school

Can I just say how much I hate dealing with my children's school?  I have fairly smart children. They aren't genius kids or anything but they are not walking around with air between their ears either. Our school district loves to hire "new" teachers or promote someone from one thing (my daughter's teacher was the school librarian until this year) to a teaching position. While I understand that these people have to start somewhere in their teaching careers, I just wish my kids wouldn't get them every single year. With Little Man, they never know how to handle his hair trigger temper. Sassy Pants always seems to get the teachers who have never in their entire lives dealt with a head strong kid before, and Little Miss is learning this year that she can't just get by on how cute she is. Sassy Pants teacher and I just are butting heads this year. Talking to that man is like beating your head against a brick wall. Not going to get anything out of it but a splitting headache. Sassy Pants talks. Anytime he can have his mouth running it is. He is a non stop chatter box. I warned his teacher of this. When they line up to go anywhere, the teacher tells them to be quiet and not talk, so of course my son has to talk. They have a color system for when they are in trouble.

Purple - excellent day!
Blue - Great day!
Green- good but not anything to brag about (this is where my kids thrive)
Yellow - not bad but had to be warned once
Orange - getting worse, second warning
Red - basically your screwed. We will call and email both your parents and you are possibly getting ISS (in school suspension)

So yesterday Sassy Pant's teacher decides that he isn't going to give him any warnings anymore. If he gets in trouble for the littlest thing he will automatically go from where ever he was on the list to red. If he gets red he gets grounded at home. His teacher knows this and has decided to use it against my son as a sort of blackmail. Be extremely good or I will put you on red! WTF?! Really? You are going to emotionally blackmail my son into behaving a little better so you don't have to stop being lazy and deal with him? You can't tell me in that whole class of 21 kids that my son is the worst. I know he loves to talk and will most likely be named class clown but he isn't violent or anything. Then, he calls Mr. Fluffy, who just happened to be taking a test and forgot to silence his phone so he automatically failed the test, just to tell him that Sassy Pants had not been turning in homework for three weeks. Really? Why didn't you tell us sooner?! This man has both of our email addresses and phone numbers so there is no reason why he could not reach us sooner than this. Why wait three damn weeks to say anything at all? I am so frustrated with their school that I just want to scream. They refuse to keep us in the loop on anything then cry about it when we don't know what is going on.
