Not knowing much about how they're delivered through the continuum, nurses, particularly practical nurses, the greater majority of whom work casual or part-time, many times will get their shifts 24 hours in advance. You may not know from a tour of duty, which is about two weeks long from tour to tour, whether you're going to have work or not. Speaking from a personal perspective, you can't very well register your child in a full-time day care not knowing if you're going to have day care or if you're going to have shifts to pay for the day care.
