Couple of points: Nurses get put upon. Will you leave on the dot at 1700? There are nursing jobs where you hand off to the next person on duty ie staff nurse, so when you go home you don't have to worry about anything, but most of the 9-5 jobs the job has defined responsibilities. Even if one is off the clock there are still thoughts running around inside your head. It takes a bit of skill to be able to put them aside every day.
It's really hard to fit everything you need to do at the weekend on a 9-5 compared to the flexibility of shifts. You have to be rigorous in terms of doing personal work in the evening after the job has finished.
Tbh have to look at career progression as well. Its not a straightforward choice.
And here I am rocking an A71 that still works fine...why spend the money?
