I know many nurses.....
Some are over-worked no doubt about it....but they put up with it.
I also know many nurses that have great hours...and make good money.
fwiw-
I spent 7 years as a critical care nurse before finishing my Master’s and becoming a nurse anesthetist. Bedside nursing is one of the toughest jobs for a whole host of reasons. However, as I said, unions are not the answer to nursing’s woes.
