"Permanent" is in quotes because there's no such thing as a permanent job, right? Downsizing happens, people stay home to raise kids, nurses burn out in one specialty and learn another, and workers leave a job for any of these reasons or one of a hundred others.
But...I've taken an RN job that I have assumed will be a job I'll work at for at least a year or more. For me it's been strange to orient at a permanent job after working as a travel RN. My anxiety level is much higher! When I was traveling, if I didn't like the charting system or didn't feel the MDs were available enough, I could always console myself with the mantra: "It's only 13 weeks!" Now, when I'm finding less-than-desirable aspects of my new job, I'm forced to recognize that I'll be dealing with those aspects for the duration of this job. And there's no "Hey, it's only 39 shifts" to make me relax.
