Left before 6 months - eligible for rehire??

I am (luckily in this economy) employed. I currently work in an outpatient clinic, but my hours keep getting cut back due to this poor economy. It is sometimes hard to even get 25 hours a week (I'm supposed to get 32-40). Nurses are quitting and not being replaced. Also, I've discovered after being in my current position for 9 months, there's really no room for growth and now no tuition reimbursement and no raises for the next year. Lastly, I'm not feeling challenged -- at all. So I've been shopping around a bit, trying to focus on what I really want to do because I don't want to continue being a job-jumper.

Last summer my husband and I relocated permanently. Prior to this outpatient job I'm at now, I was in a position for 5 months. It was Med/Surg/Tele, straight nights, hell. I became so burnt out and thought outpatient would help me regain my sanity, if not a normal sleep schedule. I had done fine with nights in the past, and even miss that shift at times, but it was the floor I was on that was the problem. I knew I didn't want to continue on in med/surg when I took the job (I had been doing it for 2 1/2 years and swore I was getting out)....but it was the only job offer I had at the time. (It was one of those that offered me the position at the interview -- maybe should've been a red flag?)

During my 5 months there, I spoke with the hospital's Nurse Retention Coordinator about my frustrations and transfering. They were all lip service..."We don't want you in a position you don't feel is a good fit for you." Nothing ever materialized, (the Retention lady never called me back and when I DID get a hold of her, she kept stringing me along by saying things like "I'm waiting to hear back from the manager of that unit and I'll let you know"). I was told by co-workers that I had confided in that transfering out of Med/Surg was nearly impossible at this hospital because these spots are hard to fill and they didn't want new grads. They shared their stories with me about internal interviews that went well and then they would never hear anything back. This led me to believe I would never be able to transfer. So I gave my notice and left after 5 months.

This same Health System (not the exact hospital, but I was an employee of the system that is comprised of 2 hospitals) has openings in an area I really want to work. I have been thinking hard about applying; I was a good employee, reliable, got along well with everyone, left on good terms EXCEPT the whole less-than-six-months part. Any chance they'd give me another try? Does anyone have experience with this?

(Sorry my simple question turned into a long post...thanks for reading)
Call them and ask if you are eligible for rehire. Or, just apply for the job that you want and take your chances. Good luck.
