Cyberbulllying was once thought of as a problem facing schoolchildren, young children and teens. However, this isn’t the only case of cyberbullying. There have been many cases of cyberbullying among adults, especially in the workplace.
In different cases, the cyberbully could be a different thing. In some cases, the cyberbully could be a jealous peer trying to scare you off the job. At other times, the cyberbully could be an outlaw manager. The one way to fix the problem is to confuse the bully and gain power over them so that their sense of power that they feel they get from bullying others is no longer a threat to you.
Victims are caught off guard and usually retaliate in the same aggressive manner. OR they take stress leave.
Again, these people seek power from attacking others, it doesn’t help to give in to their desires. Most people don’t realize that these people don’t know how to deal with real people. They’re passively aggressive, using pressure tactics to hurt others.
If you are cyberbullied at work, or even anywhere, take swift action. Document the case and report the incident to an appropriate supervisor or authority (if it becomes a dangerous situation). DO NOT cyberbully them back, that would defeat the purpose of trying to stop cyberbullying.
