It really is. Some adults do get actual snow days though in jobs you can't do under the conditions.

I work outside, I literally have snow days. Can't do my masonry job from home.

I have an academic job where I can sometimes skip work (usually when I get mildly sick, so I don’t spread it to colleagues) and I get exactly the same weird feeling of “being at home and missing out” as when I got a doctors note to skip school and stay home.

It snowed pretty hard once in Alabama, and the roads got icy so they cancelled work. Management told us that we would all have to use a day of PTO for this unplanned vacation. I told my boss “Fuck that, I’ll walk to work. You’re not getting my PTO.” and he said “You can’t do that, the building’s locked.”

I was prepared to become an Issue, but the next day they must have realized how illegal that paper trail was because they retracted the PTO thing.

A similar, much more severe storm happened a few years later, and I told my boss that I was absolutely not driving to work in my little sedan. He told me he would come pick me up and that I was a big baby, then shows up sliding around in his Prius with no chains or anything. After barely making it in, no one else was at the office and everything was dark. He made me work the full shift anyway before letting me go home, and HR said they wouldn’t give me any consideration for working a day more than everyone else.

Their have been power outages that have effected my work. The excitement of getting to go home being crushed by a generator kicking on is terrible.
