Threatened to be Fired for "patient safety" issues.

Thanks for the replies. With the exception of the hostile one, of course. I didn't post this blog to be insulted and I don't feel a need to waste time defending myself. That said, I have left the position several months ago and am currently looking for a job that works with my schedule. I feel that pretty much everything that can be said about the situation has been said. There have been no recent changes. I know that my NM has given out a false reference about me, but have yet to contact an employment attorney to resolve it. I know that HR is giving me a positive reference. So that's who I am listing when I apply for jobs.
