The bullying faced by students at school is a troubling problem with consequences that require greater attention from teachers, social workers, or parents. Harassment can cause adverse effects to those who experience these behaviors in many respects, such as physical, social, emotional, psychological, or academic. These negative effects are considered as abuses and violations of human rights. By examining some sociological and psychological theories about the phenomenon of harassment, this paper focuses on the General Strain Theory (GST) and the Procedural Justice Theory (PJT). According to these theories, when students experience such violations, they are more prone to developing violence, or preventing phenomena through social support. This paper evaluates the dissemination and development of the exercises that occur at school, identifying the relevant behaviors, the consequences of these behaviors, and the risk factors for the pupils, the family and the school. No prevention or awareness-raising program for the phenomenon of harassment can be successfully implemented without the involvement of "parties" involved in drafting policies/strategies for the protection of children's rights.
