I am in the NE and I have the luxury at this time of being a school nurse. When the weather is bad, and school is closed, I stay home.
However, it is not my call. If school is open, I go in. I hop in my car and I drive very slowly and that is that.
In the past, I have worked in a group home (not as a nurse) where I have stayed over, came in early, stayed late, many times due to the weather.
You do what is expected of you, that is all. : )
