Does anyone else have problems with one of their co-workers? If you're no longer working, did you have problems with an old co-worker?

I have trouble getting along with one of my co-workers. I swear his only purpose in life is to make people feel like a worthless piece of sh**.

He does this to everybody, not just me. Any time you do something slightly wrong, he's like, "Why did you do that? That is NOT what we're supposed to do." Then if you say it was a mistake, he says, "You were NOT supposed to do that. I can't believe you did that." It doesn't matter if you apologize to him or not. He still goes around telling everyone that you made a mistake.

I'm like, "Seriously? F*** off, douchebag."

He acts like he's smarter than everyone else, too. For example, one time I told him over an internet chat that something wasn't working. (FYI, we have an internal chat for sending messages to each other at work.) Then he was like, "It works. Why can't you learn how to use it properly?" I said, "It doesn't work." Then he snapped back, "YES IT DOES. How come other people were able to use it?" (At that point, I realized he never actually checked if it worked.) Then I showed him it didn't work and he never responded back. He can't admit when he's wrong.

I don't even know what to do with this a**hole. I have to work with him sometimes, which sucks. He's also my age, so he definitely doesn't know as much as he thinks he does... but he acts like he's been working in the industry for 30 years.
