I worked as a nursing assistant while in nursing school and understand the work. It is hard, physically work but I left every morning at 7:00 am. Now as a RN I work with some good NA's and one older very lazy NA that I'm about to lose patience with, I physically do most of her work for her and still have to remind her to do the little things.
All I can say is I left work this morning at 7:45 am and my nursing assistant left at 7:00. I have never seen an NA or CNA stay a second pass 7:00, they want us to help them with there job but they can't stay late and help us with ours!
