There is a 5th grade teacher at my school that has become very friendly with two of her students. She sits with them at lunch, brings them fast food in the mornings, and has even invited them to her son's birthday party. None of that really concerns me (I don't teach that grade), but now the students are acting out to other teachers in the building. For example, they were walking through the hallway (during class time), opened another teacher's classroom door, picked up her classroom phone and said "I'm going to call my mom." No knocking, no asking, no hello to the other teacher. They have also been overheard negatively discussing teachers and the administration with the teacher they are close with. When is enough enough? How can they be reminded that they are the students and we are the teachers? Is it my place to report this teacher to administration?
