Bullying is the use of force, threat, or abuse to intimidate or aggressively dominate others. It is often repeated behavior that involves an imbalance of power. Bullying tactics can be perpetrated individually or collectively and include verbal harassment, physical assault, or other acts intended to assert domination. Bullying occurs in different contexts such as through cyber means, against those with disabilities, or in workplace and school settings. Prevention efforts aim to reduce and stop bullying through various campaigns, events, and anti-bullying laws.
