My co-worker talks to me like I'm dirt [View All]

[undeterred]

not all the time, just when he's in a foul mood like today. So today I told him I didn't like his attitude and he exploded. He went to a manager then I did too and the rest of the day was miserable.
I could hear him talking nicely to other people on the phone, but to me he was a total asshole. We have to work together, so apparently he thinks he can get away with it- i.e., I have to put up with it.

We've had one blowup before and he changed his attitude for a few weeks, then it went back to moodiness. I'm fairly new (6 wks) so I hesitate to make too big of a deal about it, but it really upsets me. He's very moody and irritable and he controls it around customers but lets it out around me. Not ok.
