Bullying is a pervasive issue in schools, workplaces, and online environments that involves the repeated harm, harassment, or intimidation of a person or group by another individual or group. This behavior can take many forms, including physical, verbal, relational, and cyberbullying, and can have serious negative effects on the mental health and well-being of the victim. Research in this area seeks to understand the root causes of bullying, its impact on victims and perpetrators, and effective prevention and intervention strategies to address this harmful behavior.
