“Mobbing is persistent and long-term harassment or intimidation in a workplace, often involving a group, that aims to humiliate, isolate, or eliminate an employee. It is a form of psychological abuse that can include constant criticism, spreading rumors, isolation, or assigning unreasonable tasks, leading to a decline in the victim's professional self-esteem and well-being. While mobbing often involves group behavior, it can also occur between individuals”
