Very long story short, would you tell a kid that if he can't attend a class party because of behavior he can come to yours? I have a student that is very impulsive. He is in trouble more than he is not in trouble. My first year co teacher told him in front of my whole class that if he can't come to my Christmas Party because of his behavior he can come to his. His behavior is just as bad in his class as it is mine but he is taking a different approach. Every time he is bad in his class, he is super nice to him. He doesn't "get mad at him" He is not like with any other student. In fact he even told me he is overly nice to this kid just to see what happens. I am strict with all my students, I have expectations and they know it. I am not overly nice to anyone student just because I want to see what happens. I am pretty upset that he said this in front of the entire class. I feel like he has undermined my authority with my class. (btw it wasn't the difficult student who told me this it was three other students from my class) What would you do?
