1. Short staffing
When a unit runs short, the workload lands on whoever is there. You get asked to extend your shift or pick up straight duties to cover the gap. The extra hours pay, but the physical and mental exhaustion of working that long does not balance out.
"I used to be okay with working straight shifts. Then I noticed I was making more and more mistakes. The stress I could handle, but I wasn't going to risk my patients' safety. I quit," a former ward nurse said.
2. Limited upward mobility
Moving up the hierarchy now takes more than a BSN. Most advancement requires a master's degree or higher. For nurses who have been working for years, that means going back to school, often while supporting a family, and pulling time away from work to do it. For many, the math does not work.
3. Underpayment
Salaries vary by location, but the pattern holds: most nurses are underpaid, and pay tends to cap after a few years.
"Most of our new nurses make about what I make now, which is well above what I started at. It's unfair, but that's how it goes," a veteran ER nurse said.
4. Poor management
Beyond difficult coworkers, nurses deal with management systems that push them past their limits. Tasks outside the scope of nursing get delegated down to cut costs, and nurses absorb the load.
5. Too many unrelated tasks
Carrying several patients at once is the job. Getting handed housekeeping and infection-control duties on top of that is not. The extra assignments pull nurses away from actual patient care and, when they are clearly unrelated, make competent people feel like they are wasting their training.
"When I left, I didn't leave the profession. I left the system. I knew there was somewhere I'd be valued as a nurse," a nurse supervisor said.
Frequently Asked Questions
How many nurses actually quit their jobs each year?
More than you might think. The 2026 NSI National Health Care Retention Report found that staff RN turnover averaged 17.6% in 2025, up 1.2 points from the prior year, with individual hospitals reporting rates anywhere from 5.6% to 40%.
What does it cost a hospital when a nurse quits?
A lot. NSI puts the average cost of replacing one staff RN at $60,090, and the average hospital loses several million dollars a year to RN turnover. That math is part of why retention, not just recruiting, has become the priority.
Is short staffing really the main reason nurses leave?
It is one of the biggest drivers. When a unit is understaffed, the remaining nurses absorb extra patients, longer shifts, and tasks outside their scope. The American Nurses Association has flagged unsafe staffing and excessive workload as central to its nurse staffing crisis work.
Does leaving a job mean leaving nursing?
Often not. Many nurses who quit a specific job move to a different unit, employer, or specialty rather than exiting the profession. They are leaving the conditions, not the work.
What can make a nursing job worth staying in?
Protected nurse-to-patient ratios, fair and progressing pay, management that keeps non-nursing tasks off the floor, and a path to advance without going broke. When those conditions hold, the reasons on this list mostly disappear.
