While it's not always possible to completely avoid a co-worker, you can strive to keep interactions as infrequent as possible. Simply avoiding interaction is probably the easiest way to cope.  Some interactions are probably unavoidable, especially if you two work together directly. However, you can avoid chatting with this co-worker in the break room or during downtime. If you notice your co-worker come in, politely excuse yourself by saying something like, "Well, got to get back to work. Nice seeing you."  When you do have to interact with the co-worker, keep things professional. Avoid bringing up personal matters or things irrelevant to the task at hand as, when dealing with someone who dislikes you, this is an invitation for negative interaction. Many psychological studies indicate that it's very difficult to dislike someone who likes you. If your co-worker feels you respect and like him or her, some of the dislike he or she may have towards you might fade.  Tell someone else in the office that you like and respect the problem co-worker. That information may get repeated secondhand. When such a message does not come directly from you, your co-worker may be more likely to believe it. Show a genuine interest in your co-worker's input. People tend to like people who pay attention and engage with them. While you should still stick to avoiding this person when possible, during the times you do have to interact listen to what he or she says actively. This might make your co-worker's dislike you less.  Small, friendly interactions can help as well. Something as simple as "good morning" can go a long way. If you have trouble interacting with a particular colleague, try to separate your work life from your personal life. You do not have to socialize with colleagues outside of work. If the co-worker who dislikes you is frequently part of Friday night happy hours, forego these events and seeing the friends you know from outside work. You do not want to report behavior unnecessarily. However, you should certainly report any behavior that's interfering with your ability to do  your job. Talk to Human Resources if the situation gets out of hand.  Management can help negotiate situations if your ability to do your job is threatened. You should keep a record of your interactions for a week or so if you plan to report just so you have solid information to show to officials.  Make sure you focus on how your co-worker's behavior affects the company. Speak in objective terms and explain about how productivity and morale are damaged by your co-worker's attitude.  Remember, this is a last resort. You do not want to get labeled the office tattletale. You should only report your co-worker if you feel he or she is harassing you, attacking you personally, and is persistent in his or her actions despite your attempts to avoid or rectify the situation.
