You may be reading the title of this post and wondering "Why would you be talking about personality conflicts when you work with technology?" There is an answer to your question and it's quite simple.
Simply put, unless you are a hermit, you interact with people every day. In today's world, much of our communication is electronic and not in person, sometimes making conflicts more apparent because we don't know how to deal with other people.
Here are a few things that I keep in mind when I notice a personality conflict in support:
Don't Let Conflict Bother You
This might be difficult for some, but the moment you let a personality conflict get to you, you're not going to do your job as well or convey what you need to as clearly.
Often when I start realizing that a conflict is getting to me, I will ask the customer to let me do some research on the issue so that I can take a few minutes to gather my thoughts and clearly convey what needs conveyed, or ask them if I can hand them off to a co-worker whom they may not have a conflict with.
Don't Let the Conflict Carry Over
If you have a conflict with a particular customer, don't carry it over to other customers that you work with. As soon as you carry the conflict over, the current customer is going to be less willing to work with you.
Your current customer does not care about the conflicts that you have with other customers. While in some cases the customer may be sympathetic to your situation, they usually don't care about your conflicts and just want their issue resolved.
Never Take the Conflict Home
This is probably the hardest for me. I try to help everyone that I work with be more efficient and effective in the way they work. Often when there is a personality conflict, I'll take that home with me and it not only keeps me from enjoying my time with family and friends, it causes me to constantly think about how to resolve the conflict and the issue that caused the conflict to arise.
I know these are all very closely related, but these are some thoughts that I've had over the past few weeks. I hope you can take these for what they are worth and use them as you see fit.
