Acharge nurse, depending on your facility can have many responsibilities. She can:
1. delegate admissions,
2. delegate breaks,
3. determine if there is sufficient staffing for her shift and the next shift and modify as needed.
4. take charge in a code situation,
5. be available to all staff nurses for questions on policy and procedures.
These are the few I can think of. I think she deserves a little extraa money for it. I certainly wouldnot do it for free.
At our hospital they pay a whopping 0.60 an hour for the task.
