Should have called in sick. Sick of the snow.
It does not matter what you "call in" for in health care.
Most of the hospitals have draconian policies that can get you fired for going on funeral leave and staying home with a sick child...forget about getting sick yourself. They don't care what you were absent for, if you have x amount of absences (most times it's three or four) within a six month period...you are gone...I kid you not.
