Each person will encounter his fair share of bullies in life. There will bullies in school, in cyberspace, and even at your workplace. Dealing with bullies is never as simple as standing up to them or beating them at their own game when it comes to dealing with bullies at work. Most often than not, these bullies already have a solid foothold on the company and, most likely, has a high ranking position. However, there are several ways of making the situation better.
Go to the boss
Unless the bully happens to own the company, most likely they answer to someone. If the bullying persists and you feel that it has gone too far, you can always tell a person of higher authority. Unless they want to get fired, bullies will not cross their boss. Just be confident and tell them that the situation is interfering with your work.
Go to human resources
Every company has a set of rules. Each of these rules is supposed to be enforced by the human resources department and give out any kind of disciplinary actions needed for violations.
Bullying, in any form is not tolerable. Unless, the person is really a big influencer, the HR department can handle it.
Leave the company
At the end of day, a negative work environment is never what you want to be part of. The stress will just double and in the long run, and the quality of your work will suffer. Your health might just also get affected. Having a fresh start somewhere else may just be the thing that you need.
