zl1camaro said:she's undermining your authority. Did she say that in front of others? If she did then that makes you look bad, if it was in private then tell her don't do it again but make sure you stand by that.
No, we were in private. The biggst problem with this person is that we used to be roomates, and then she came to work for me. Because of this friendship she thinks it is appropriate to sometimes say and do things that are NOT. I had to write her up today because she was late for the second day in a row. FTR she has worked here two years now and is maybe getting more comfortable.
