Office politics

I feel like I'm getting the first taste of those things that you only see happen in movies about office gossip and such. Gladly, I am on the outskirts of things but I can see how I'm going to get pulled in rather quickly by the office "mates" I have made and those that I haven't. Being an analyst puts me at somewhat of an advantage because I don't quite work in the trenches, so to speak. I don't have any direct say as to how things "should be" or do the work they do or know the rules that should be followed or broken. Well, in essence, I know the rules but on the computer side of things.
Anyways, I guess rules weren't followed somehow along the lines by some people and they were by others. The problem was that the supervisor was the one not following the rules and was training new people in the wrong way. Now, my "friends" have been doing it the right way and been doing so for awhile because they implemented the change after a meeting and I'm guessing assumed the supervisor had done the same thing. (The whole problem with this entire process is the fact that there is NO process. Changes are implemented and it's like management just hopes things will take or something.)
Aaaaaaanyways, so I guess last Thursday, the supervisor was training some people and my friends heard her and corrected her. The supervisor got upset and tried to stand her ground, being supervisor and all and in turn, inadvertantly accused them of either lying or holding things back from her. Quickly enough it escalated into a who's side is who's and what is the way we've been doing things and who's allied with who.
Things ended in silence BUT this is the part that I don't like. Everyone is, of course, entitled to taking their own time and doing what they want on their own time. But, that evening, the allied ones with the supervisor went over to her house and sat around, having some drinks and hot tubbing. Things were obviously assumed to have been said. This is a bunch of women, after all. And now there is silence in the office between the 2 groups.
I get to hear about this today of all things! This is because I don't sit on the floor anymore, I'm in an office. I'm also getting pegged as anti-social but I'm thinking that's probably the better way to play it right now. It's just part of my job has me interacting with one of my friends so I got to hear about it and understand why it's so damn quiet out there lately. Also, it kinda helps that I was sick yesterday.
BUT did I get looks today! I usually do the polite office "Good morning" or smile but today, I wasn't greeted or smiled at in return. *sigh* How sad. I wonder how tomorrow will be as I have another day with my friend in my office. And we laugh and giggle. I'm sure the gears will be aturning tomorrow about what we "MUST BE SAYING" about the others. And our manager is gone on holidays. *ACK*
