In the 16 days my husband spent in the hospital every other nurse we met was great. Yeah, he was that sick. Sorry, Barbie was not doing her job that night and is lucky that all she got was a minor jab from me. The other nurse know it and told me to come to her if he needed anything else.
As to the rest they work 12 hour days by choice so they can have four days off and I have yet to meet one that worked at two hospitals for a total of 72 hours. In most places that would violate union rules. Maybe your area is different.
