Real talk, I've worked for some horrible employers back home in Wichita, but -never- has any fired me for taking time off due to an emergency. If anything, they said, "go and take care of it." And that was that. I don't know what part of the world you come from but even in Kansas (a very socially and economically conservative state) we don't haggle people over three days off for an emergency. We suck it up and deal with it.
