I would have reminded her that although she hasn't been around long enough, you definitely have and my record should speak for itself. That's what I would have told her. And if I was mad enough, I would have told her that because I now see that she's the type to bet the farm on petty rumors spread by petty people, I would be watching her closely in the future. I would really be upset. Any supervisor worth their salt knows that you don't accuse people of things you have no proof of. That's just ridiculous.
