I recently accepted a position at a new ED and have filled out and sent in the paperwork, but will not start orientation until next month. I wanted to resign in my current place of employment due to a physician that enjoys threatening licenses among other things, but this is a complete other story.The meat and potatoes here is that I am currently studying to be a psychiatric nurse practitioner, and today after I submitted my paperwork accepting employment, I received an email from the inpatient psych unit in my hospital offering me a PRN position until another full-time nurse resigns in October. I'm now extremely torn. The psych unit is where I really want to be, but I don't want to say no to this other job now that I've already accepted this other position. Any advice?
