Any job that deals with the public is deemed as a job that people can’t just call in and take a day off in my book. There needs to be coverage. Mall, hospital, home health care, hotels, and more. People who sit behind a desk, and can just get to the work tomorrow, or reschedule meetings, is very different than having to be somewhere in front of another person.
Ice is a killer. It is almost impossible to drive on ice, and this is why the south has so much more trouble than the north, besides being less experienced driving in wintery conditions. The south hovers around the freezing mark all too often, above and below, so snow is very heavy and wet, and things melt in the days time, and freeze to sheet of ice during nightime hours. Not to mention almost nobody has snow tires on their vehicles. Northern cities frequently have below freezing for extended periods, the snow is more powdery and dry.
Four wheel and front wheel drive, and being more inches above the road, help get through deeper snow, but it does not help stopping, and braking is the biggest safety hazard in winter conditions. Another thing southerners seem to not grasp. Too many people I know talk about driving through the snow, when the real deal is driving slowly, and keeping your distance from other cars, and using your brakes as little as possible. Being familiar with your ABS brakes and how they function, or pumping your brakes when you need to use them.
So, my answer is, if you have to go to work, you give yourself plenty of time to get to work, stay on the beaten path, as few back roads as possible, keep a bag of kitty litter or salt in your trunk if you are worried about getting stuck on ice and having no traction. Along with keeping a blanket in case God forbid, you have to wait for someone to pick you up if you get stuck.
