A colleague of mine has gets on my nerves, half because of the way she does things, half because of the way I'm wired. Recently she brought up an issue which I think was just a waste of time and an artifact of a derailed process, and also she negleted an, IMHO, really important issue.
My response was bad. I responded with irritation and then snarkyness about other things that were also bothering me. This eventually drew in one other coworker and our manager and I'm really sorry they had to endure all this irritation between us going back and forth.
Edit: This happened in the late afternoon in an open-plan office when most of our co-workers had gone. We were 'arguing' (restating our positions in increasingly irritated voices) for about 10 mins and then the other 2 joined in for another 10 - 15 mins. In the end we reached an agreement on what needed to be done, with the help of the other two.
I would like to clear the air (maybe gauge if the air needs clearing first) between myself and said colleague and maybe also apologise to my other coworker and manager.
The way a handled it was counter-productive. I still feel i'm right though, so I want to apologise for my handling of the situation without taking back the content of what I said.
There is a vaguely related question on the inter personal skill forum, but my question is about a workplace setting.
