Harassment is a form of repeated aggression directed at another person. It can take several forms, including physical, verbal, relational, and cyber harassment. Physical harassment involves hurting someone physically, while verbal harassment uses threatening or insulting words. Relational harassment disrupts peer relationships through social exclusion or rumors. Cyber harassment uses technology to bully others. Being harassed can negatively impact students' self-esteem, grades, and mental health. Common signs of harassment include a sudden dislike of school and depression. Schools should implement anti-harassment programs and interventions for both bullies and victims to address this serious issue.
