Bullying and especially Cyber-bullying simply can not be tolerated in or outside of the classroom! I am part of the No Place for Hate initiative at my school that works to create an inclusive, empowering, and engaging environment for students. We try to get all (or as many as possible) students involved because it needs to be a school-wide effort to succeed!
