As a travel nurse at Mount Sinai, I can absolutely confirm that no travel RN is making $500/hour. The money is good, yes, but certainly nowhere near $500/hour. And yes, they want a 30% raise over 3 years. 10%/year. It will save money in the long run because it won’t last that long. But theoretically, yes, if it did last a long time, which it won’t, it would become more expensive at a certain point. But I do not see that ever happening.
