Bullying in schools can take overt or covert forms. Overt bullying includes physical acts like hitting while covert bullying involves social exclusion and rumors. Bullies typically have high self-esteem and seek power, often coming from homes with harsh discipline. Victims are often insecure with low self-esteem. Adults often dismiss bullying as harmless, but it causes long-term harm like depression. Schools should implement anti-bullying policies, curriculum, and programs to address this issue.
