Here in the UK, it really depends on the school. Council run schools tend to shut as soon as the snow starts falling, but other schools (like the grammar school I went to, which was council-affiliated but run separately by a board of elected governors) vary. My old school tended to stay open unless it got really bad, which never happened while I attended the place, though the year after I left I was informed by friends still at the school that a snow day was indeed called. For barely an inch of snow.
Now though, at university we have to make it in regardless, it's down to the lecturers themselves to cancel or postpone things since the university doesn't take responsibility for them. So if the lecturer can get through the snow then we all have to, or try and catch up (which thankfully is pretty easy with online resources

). I live about 200m away from campus anyway, so it's easy for me to get to uni. As for work, I still have to make it in if possible, I work at a supermarket so we could close if there's massive trouble and no-one can get in, but usually we stay open (we haven't had to close so far

). Though one day was really bad, I was the only person on my section to get to work aside from the manager (there's normally at least four or five of us on at any one time) and we had to get cover from other sections to help us out. To be fair I did spend ages helping people push their cars up the massive hill outside the store before my shift started, so it wasn't just us who were working who had snow troubles...
I dread to think what it'll be like next week though. My dad's picking me up on Thursday next week so I can go home for Christmas, but he'll have to drive from Birmingham up to Leeds and back (for non-UK Escapists that's roughly 120 miles each way on the motorway), and the snow is supposed to start again by then and make it insanely tough to travel. I can't even get the train instead because they reckon there'll be too many delays...
