The last few months I've dealt with some real mean girls. I've always said if you've got haters then you're doing something right. However, to help anyone else out who might be dealing with this or find themselves dealing with it in the future here's a few tips:
1. We can all agree that not everyone in the world is going to get along. People are different. We like different things. We have different view points. We have habits and dislikes that others like and love. We are all adults so let's agree to disagree and let each other be.
Trash talking others to co-workers. That just brings it into work. Don't do it. Steer clear!
3. Sometimes friendships end for whatever reason. Wish the other person the best and be done with it. Don't talk about them and talk about their business with other people. If people want to engage you into talking about them either tell them A) I'm not going to talk about them/it. or b) It's not something worth talking about and change the subject.
Real life mean girl or girls won't leave you alone. If you're in school- report them. If you're in a work environment- report them. No one likes a mean girl, especially a dean/principal and especially not a boss. Most work environments have an HR or a way to talk about working in a hostile working environment.
Vent it out. Write it in a journal. That's the beauty of a journal. It's private and yours. Its not out there for the world to see. Be classy.
Lock it down. Real life mean girls love ammunition so stop their news flow. Make sure your facebook/twitter/instagram is all private. If you don't allow them to follow you then you've at least put a stop to them seeing it on their phones/computers.
7. I know you really want to do this....
It's tempting but don't do it. That's just what they want. Breathe in. Breathe out. Eventually the mean girls will move on or learn their lesson. Either way you'll be a stronger person and prepared for the next time another mean girl comes along.
