does it make sense to ask your soon to be former coworkers if they'll work there in 2 years?

the idea is to use your soon to be former job as a fallback option.

I'm a nurse looking for an office job, but it can be it turns out to be something I don't like (never worked an office job). I was thinking of giving it 1 to 2 years to see how it is.

If I have to use my current bedside position as a fallback I don't want to change specialties, cause that would mean being treated like a newbie all over again, something I want to avoid.

I get that people are constantly looking for better options and 2 years might be a long time. The current coworkers that make the job amenable might also leave for greener pastures before I come back, if ever.
