I don't think there is that much turnover. I've been there over a year now, and I can only think of a handful of nurses who have quit. There are a few there that have been there 5 years or longer. We have around 50-60 nurses, so some turnover is to be expected.
I think the 1st 3 months would be hard, it was hard for me to get comfortable with phone triage for the 1st few months. I think you would be able to do it, though. We talk to a lot of parents about sick kids, lots of coughing, vomiting, diarrhea, colds, and things like that. It is much less stressful than any nursing job I have ever had. Working from home is the best, too!
