Holy cow. Are you me writing under another name??!!
I have the same problem!! Last week it got so bad that I did say something. There are three members of another team (I sit in cube land) that are SO loud and literally talk ALL DAY LONG about nothing work related. I've mentioned to my boss that they are too loud, I've had customers/coworkers on the phone that can't hear me because they are so loud, and one of my coworkers leaves early on a regular basis because she can't get her work done.
So last week they were smelling all of the samples to a candle magazine and going on for hours about how they smelled like dirty gym clothes, stinky arm pits, etc...gross. Othe conversations have included things such as strip bars, what the boss eats every day for lunch, and other stupid things. The conversations (and one extremely annoying laugh) go on from 7-330. I work from 630-330, but they don't start rolling in until 7.
The main trouble maker rolled her eyes at me and turned around, the other two apologized. I had to work late that day and they started getting loud again around 4, but I'm normally gone by then. The rude girl left and told the annoying laugher to "be on her best behavior" and I laughed so loud they knew I was still here.
I am all for having fun at work, but not to the point that it makes it hard for others to get their job done. And that is how these ladies act. They are "new" as of March and sometime late spring because we had a big contract switch and all of our really good people left...sucks big time.
So the one girl who was rude will probably be nasty to me until she leaves (which I hope is sooner rather than later, but I doubt it). The other two are fine...I'm glad I said something though, because it needed to come out.
