What to do when you don't like your colleague.
And since you can't choose the people you want to work with, and you most likely don't want to have to leave your job, you can do a few things to maintain your sanity around the co-worker who makes your blood boil.
1. Check yourself
Often times, when you hate people it's because they have a character within them that you hate in yourself. Accepting yourself and your flaws can go a long way in helping you manage a cohesive relationship with the coworker.
2. Document their bad behaviour
If your coworker is someone who is manipulative and a liar, ensure that you keep a record of any offences they may be making. This is especially if you have no power to dismiss them. If you're in a position to report their troubling behaviour, go ahead and do so.
3. Change your interactions with them
Avoid them if possible. If a conversation with them can't be avoided, always try to include a 3rd party.
4. Don't gossip about them
Your dislike could be because of a personal preference when it comes to people you would rather interact with. Avoid the urge to badmouth your coworker as it may come off petty and resentful. And could even get you in trouble if you make it a hostile work environment for them.
5. Don't threaten them
Never send threatening messages to get them to stay away from you.
