According to the national curriculum in Swedish schools, teachers have the responsibility to prevent and discourage psychological and physical harassment (Lgr 2011). This study focuses on 7 teachers with their viewpoint and understanding of bullying as a human based social problem. The teachers, as the informants, give their personal explanation on how they act, prevent and discourage bullying in their school. The research places the emphasis, based on, interviews from which teachers are telling, relating and explaining on how they say that they are preventing and discouraging bullying. The conclusion from this study is that the interviewed teachers do, from their viewpoint, understand bullying as psychological and physical harassment problem which is based on a question of interpretation in regards to the victim. The informants do place different emphasis on what causes the problem, if it is a question of the individual or of it is a problem based on the socialization between individuals. The conclusion is also that the teachers know how they should and would act in the prevention and discouragement of bullying in school by continuously making conversation with students about bullying and their behavior. Further more the conclusion is that teachers within their school cooperate and that they receive support from their schools by further-education in how to work with the prevention and discouragement against bullying.
