I've worked in northeast USA and Canada for 30 years. We've had tons of ugly weather, and the funny thing is, I've only gotten truly stuck while still in my own driveway. If I get out, I'm good on snow or ice. But I call a tow truck if I am scheduled to work, I don't call in until it's nice out.
I think we need to buy cars with winter driving in mind, have an emergency kit in the car, and live close enough to main roads that we'll be plowed enough to drive. If you live in the boonies, get your own plow, because you committed to show up for work.
All my jobs, I've had my own very well prepared vehicle, and a secondary plan if mine can't make it in. Taxi services that run during the storm, or a fellow nurse with 4 wheel drive will do the trick. If you sweet talk a coworker, you might get someone that's getting off to come give you a drive in too. But get the snow tires, be ready for the storm before it happens.
