I live in Central Michigan, so we get a fair amount of snow, the majority of it from January-March. They're not as great about plowing as they should be here, so yes, sometimes the snow is loose and not packed down, and it's icy. I do have an indoor stationary bike for when it's an absolute no-go, but I'd like to get out there as much as I can.
Me too, in the Lansing area.
If you really want to fit 4" fat tires you will in fact need another bike, so the shop would not be steering you wrong there. But, if you want to ride the bike you have and ride mainly riding for fitness on (sounds like) snow covered roads and pathways, you would be well-served by a set of studded tires sized to fit your hybrid. Something like the Suomi Hakkapeliitta W240 in either 32X 700 or 40X700 size should fit your hybrid fine, assuming it has 700c wheels. (most do) Scroll down here:

You local shop may be able to order them for you or something similar. Don't flinch at the price-compared to 4" fat tires (not to mention the wheels and frames made to fit them) they're a bargain. And they'll be slow and heavy, good for getting a quick work out in unpleasant conditions, and when you put your summer tires back on you'll feel like you're flying.
Also, consider trying skiing. Either cross country or downhill, depending on what's available close to you. Or even snowshoeing.
