I do home daycare in MN (almost 15 years), so we get our share of ice and snow issues. I have never called daycare off..even when and Ice Storm knocked out the power..we made do with a small generator).
However, there have been many times where I sat here with one kid, parents were of course very late...hours once..due to the roads. I since decided that if the schools close..then the State advises no travel...I can make that decision to close as well. But I get no paid vacation days, so if I made that choice, it would be unpaid. But...if I stayed open, but no one showed up..if they all took the common sense route and stayed home and off the roads, I would still get paid. But in the end it would work out for everyone I am sure. I am pretty easy going that way.
I will assume there is snowy weather there. I get Facebook updates from a College my daughter is considering in Colorado (Rocky Mountain College of Art and Design) and there update about an hour ago said something about classes going on as usual this afternoon....
So my only thought is she may go by state advisories if any are in place, or if the schools closed, she uses this as her policy guidelines and all of this may be in place to serve as a blanket policy to attempt to keep everyone safe? They should make sure they read the policies so they are prepared for such events.
