You still have times when there is nothing to do?
I haven't seen that.... in decades.
If there is no patient care there is documentation. If there is no documentation there is administration/supplies. If that is done there is something to clean.
And if that is done there might be a paper/medical book to read.Or discuss a case with someone.
...Okay, you got me...I am a former manager.....
But tbf, we have sacred break times here, but when you work you work. (And well, we have less hours than people in other countries)
