How do you deal with someone at work who hates you for no apparent reason?

1. Ignore them for anything other than professional, work-related interaction. Maintain your composure, be kind and non-reactive. Don’t let them elicit any behavior from you, as that is their reward. When you look at them or speak professionally to them, use conscious effort to focus and hold your gaze on the spot directly between their eyes.

2. If you're in an office environment, a paper trail is your friend. Do every possible interaction with that person in email. If you're in a meeting together, immediately send them an email summarizing what you decided. If they decide to go nuclear on you, it won't be just a they-say/you-say situation. Proof will be on your side.

4. Focus solely on the job and the tasks at hand. Don't talk about anything that isn't business related with / around them. If they start talking about something not business related, remove yourself from the situation. You're not going to get along with everyone you work with. Some people will hate you for no reason other than you remind than of someone they knew once. I had this older woman that worked for me who was extremely rude and short with me all the time. Eventually I called her into a meeting with HR to let her know I was sick of it. She insisted she was justified in her treatment of me because I reminded her of her ex-husband from the early 80s. I wasn't born until 1986. Some people are just fucking nuts, man. Don't let that hinder your performance at work, nor the pursuit of your professional goals. If you want to really give this person a reason to hate you, succeed and excel at your job in a respectful, honest, and professional manner. The other person will destroy their own professional reputation with their envy of you.

5. In scenarios like this, I've always found that the best way to approach the conflict is to confront the problem directly rather than ignoring it. When you get the opportunity, take them out for a coffee, or a beer, so they feel more comfortable in a slightly less formal setting. Explain to them that you feel like there might be some tension, and ask them what you might be doing to aggrevate that tension. Make sure to be engaged, attentive, and to let them know that you are open to finding a solution to the problem.Then, show them your 12 inch dick.

6. Be particularly polite (hr can't say you're instigating or escalating the problem that way) and take immense joy in that fact that you ruin their day by walking in the door every morning. Treat it like a game. Have fun with it. Source- I'm a vindictive fuck and I love watching people dig their own grave while I come out smelling like roses

7. This happens when they feel you're a threat to them. I'd recommend any of these options: - Ignoring them - Becoming their boss - Having sex with them - Killing them

8. Let them know youve noticed and ask if youve ever done anything that woukd elicit such a reaction. "I cant help but wonder, In the time Ive known you, you always seem irritated with me. Is there a reason? Id like to know so I can address it." Some people arent aware of their vibe they send out.
