And if they don't
find a way to outright fire you, they will harass you and "write you up" and call you on every tiny omission or infraction until you give up and quit. Having a union doesn't always help, either; mine didn't do a thing for me when I was going through this, probably because the reps were too rushed and overwhelmed with their own workloads to be able to help another drowning nurse.
I think human nature also works against us, preventing us from getting together to solve this fast-growing problem of what I call "nurse abuse". It's that herd mentality: we see a member of the herd being shunned (the reason doesn't matter), and as they grow weaker, we start shunning them too---not only because we naturally want to be counted among the strong and healthy, but also because we're afraid the same thing might happen to us.
I have no idea how to deal with this problem in hospitals; all I know is, it's going to take some VERY high-profile deaths and egregious cases of patient neglect before anything is done about the "nursing shortage", and even then, nurses will take the brunt of the blame. As the shortage becomes more acute, the public MIGHT start looking at hospital administration and for-profit healthcare as the principal issues, but only if a large number of nurses "go public" with their dissatisfaction..........and that usually happens only after they are no longer working for a particular facility, or working in nursing at all.
