We are talking about the people who clean up the nastiest human waste that our bodies are capable of producing. I was already surprised that this number was ever less than 100% tbh
I couldn't do it, and god bless them, but that is unlikely a cause of people leaving the profession - that would be like a computer programmer saying they were leaving the profession because they suddenly found out they have to stare at a screen most of the day.
I also find that '90%' number suspect as someone that works very closely with the healthcare community - there is a lot of turnover, and its hard to hire nurses right now - but almost always when someone leaves their job it is because they went down the street and got a 25% raise, i.e. they didn't leave their profession, just their job.
She left the profession due to the long hours, low pay, and poor treatment.
