The purpose of this study is to analyze bullying behaviors from an interdisciplinary perspective: legal, psychological and pedagogical. From a legal point of view, the Romanian legislative framework on respect for children's rights has undergone a number of changes in recent years with the accession of Romania to the European Union in 2007. International legislation on respect for children's rights requires countries that have ratified these provisions to ensure that they are respected and to take measures to ensure that they are not prejudiced. Aggressiveness in students is a predictor of antisocial behaviors in adolescence and adulthood. The psychological perspective of bullying refers to the consequences of this type of behavior. Students involved in aggression are at increased risk of developing a range of psychosomatic symptoms, involvement in delinquency, alcohol and drug abuse, absenteeism. The consequences of these behaviors on the victims are associated with anxiety, depression and suicidal ideation. Through the pedagogical approach to bullying, we focus on the role of teachers in addressing the issue of aggressive behavior in students. The perceived gravity and teacher's response to bullies and victims of bullying are important indicators to be taken into account in making a successful intervention.
