Work can be stressful as it is. Working with different personalities for hours on end can bring out the worst in all of us. So how do you deal with a mean co-worker?
When a partner is rude to you, it may be difficult to immediately respond. Some people are inclined to let violent actions slip in the expectation that the offender will quit. Others have found themselves trying to fight back. Whenever a colleague treats you poorly, how can you change the trajectory? So if the conduct continues or worsens, how do you know what you’re dealing with?
Understand The Source
The first step is to understand what’s causing the behavior. We can never fully understand the action be we can try to understand its source. Try putting yourself in your colleagues shoes. Consider that maybe you were the first aggressor and your colleague was just reacting.
Stand Up For Yourself
Don’t be scared to publicly state your discontent with the treatment. This is hard to stand up for yourself, because if anything goes wrong, it will be recognized and revealed. It’s good for the heart because no-one is supposed to live the wrong way. Standing up against something that’s unfair is demonstrating the power of the character. In doing so, you build a happier future for yourself and others.

Enlist Help
Never be afraid to tell a superior about the abuse you have been experiencing at the hands of your coworker. More often than not they will listen to both sides and come to a verdict that will alleviate the situation.
Conclusion
When you work with someone who frequently argues or mistreats fellow workers, you can dread going to work even though you enjoy your job. Workers have a tremendous effect on their workers’ workplace results and job satisfaction, and a weak work ethic and disposition may drive coworkers to other employers. Hence deal with a mean co-worker swiftly.
