This is a horrible example. My wife is a senior ICU nurse and deals with this. Getting through nursing school and being a nurse are completely different skill sets. Some of the new grad nurses are genuinely dangerous with their patients and are unteachable. Some never develop the independence that nursing requires. Some straight up play doctor and are a lawsuit waiting to happen. This has the same energy as a cop union getting a violent pos reinstated.
Every decent union contract I have seen has an employee improvement/termination process outlined. Management has to do their job and follow the process outlined.
The nurse might be an absolute screwup but the management obviously failed to follow the procedure. So the recent grad got her job back… for now…
Her post would seem to hint otherwise.
