Wow! I'm so sorry this happened! I have no good advice....because that is so shady and scary to me.
I am only taking pre-requisites now, and not even in school yet....but these are the kinds of stories that bother me about nursing. Be all you can be, nice, etc., and things STILL go wrong. That is crazy.
Can you call another meeting with her, and specifically ask about the incidents, and at least be able to respond to those incidents? So she has your side of things?
And, say that you want to keep your job, so you are willing to work with her. If another incident happens, can she tell you RIGHT THEN, so you can share your side of the story?
That is shady to tell someone 5 weeks later....or however much later. I would be worried if she doesn't even want to try to address these concerns with you. I mean, you are MORE than meeting her half way. I would be suspicious of ANY work place that would rather fire someone than even try to work with them, know what I mean?
I hope it all works out for you.
The only good thing I can think of is that if it's not meant to be, then it's not meant to be, and maybe this would just make you find a better place to work, where your patients skills are more appreciated, rather than which "clique" likes you or not, ya know?
