Apparently, you have been fortunate enough to not know what hiring for a new grad is like in Denver. I graduated in Aug. from a school in Southern Colorado. Graduated with honors, held positions in many organizations, was a nurse intern. Still have no job. Everyday I get up and I sit for hours on the phone, online, etc. trying to get my foot in the door. The whole new grad RN thing in Denver is, to just put it short, ridiculous. Right now, I am seriously having to consider moving to another area to get an entry level job, let alone be in a specialty area, and I'll be working nights. So, I just read your blog, and while some of your concerns are valid, I do think you are being a bit choosey and are taking for granted the job you already have. Especially for being in the ICU already...the new grad positions (and you will still be considered "new grad" even with your 8 wks experience) are really just the ones at hospitals no one else wants (psych, rehab, etc. and they are all night positions, but 70 people want them, because they are in the same boat as I am)...and they aren't hiring at this time of year anyways. BTW, Children's isn't hiring new grads, and I assure you that the NICU won't hire you, even if you did spend time there while a student: being a new grad is a whole different thing. Trust me, don't do anything drastic.
I'd kill to be in your shoes right now. If you decide to leave, why don't you give me a heads up because I would take the job your leaving. I hate that I sound hasty and really negative, but I really want to impress into you that the situation could be a lot worse and that there are people out here in unemployment land who are having a rougher time than you (and your being paid too). It might be beneficial to just accentuating the positive inorder to get through this first little bit. So what that you have a new preceptor every day...this way you are getting to experience and examine different ways to go things (you could get stuck with someone you aren't compatible with and spend months loathing that person and the exerience) and I think it is reasonable to request an 18mos. contract or pay for the course, otherwise they are paying for you to attend a class and you leave anyway (expensive). Besides, what is 18 mos.? Nothing, and if you stick around long enough, maybe you'll see you end up liking it afterall. Save up the money in the meantime, and if you break your contract, all you'll have to do is pay back for the course, yet you got more than 8 wks. experience out of it. And some time to look for positions elsewhere.
Again, sorry for the pessimism and negativity but, like I said, I am trying to give you the flip side.
