What is the work you do? And did no one come to talk to you about what she said because it's kinda a "given" that she's full of crap? or that what she did is out of the norm and no one wants to be involved, or hear it? I mean, is it normal to complain about a co-worker to a group of co-workers? Where I work, if someone did that, they would be "out". They would be reported for trying to start trouble because it is so unprofessional.
