At our small company, we used to have group meetings based around a particular business function.......sales, support, etc. Just recently the powers-that-be created a whole new structure called "Working Groups"......spelled out in black and white. It doesn't seem to vary much from the way it was. But now it seems ALL the conversations, ALL the e-mails from the top few people HAVE to include a reference (or multiple references) to Working Groups, no matter what they are talking about.
I hadn't heard that term before, but in just a few short days, I think I'm tired of it!!
Oh well, if that's what they want/require, I can fit it into my vocabulary also (I think).
