Look... I am only assigned to take care of this woman, not her husband. He has his own aide. Sure, when his aide doesn't show up, I do things for him, because I have to.. doesn't mean I should have to care for him when he has an aide. His lunch is ready to go. Take it in and feed him. You are assigned to him. I'm not doing it.
Hey when I'm a nurse making twice what I make here, I'll do twice the work plus some!
