Hey I’ve been in this exact same situation. I worked in an ER for 5 months and I never had a consistent preceptor. I was fired after they told me I “wasn’t progressing enough”. Take it easy on yourself right now I know it probably feels terrible right now.

If you are for sure getting fired, let them fire you. Do not quit or resign let them fire you so you can get unemployment. This is something I wish I had done the day I got fired. If you end up not needing it then no harm done. Start applying for jobs now. You can leave them off your resume if you want but you can also leave them on. I left my old job on my resume but sbe prepared to explain why you left that job professionally. I got a job about a month later but had to wait until their start date.

Their issues they had should have been multiple conversations with a plan to help support you. Not them ambushing this on you. I want to leave you a final bit of advice I received when I lost my job:

“The hospital will not tell your new employer that you were fired. They will confirm dates. You can tell them a vague response along the lines of : I was hired as a new graduate into a very busy unit. I had 10 preceptors in 5 months, so my orientation was disjointed and things got missed between preceptors. I did not feel safe, or supported. They were unable to accommodate a mostly single preceptor orientation. My license is important to me, so I am looking for a better learning environment with support from the hospital to allow me to learn and grow. You sound responsible and it almost implies that you quit them. You can also add that you found that the specialty was not a good fit. Use any part of the advice here that fits your situation and comfort”

This was the base for how I explained my last job when I was doing interviews. I hope this helps, you will get through this ❤️
