Being a teacher in Scandinavia, I get ridiculous amounts days off during breaks. And having a kid in preschool, she brings home colds a lot, so I've had to take a lot of sick days these past two years (though a lot of them have been wfh-days too).
That said, apart from sick days, I haven't taken any non schedulad day off in for the last decade or so. Basically, you're going to have to mop up your own shit of you aren't there to teach your class. Substitutes aren't guaranteed, and even if you do get one, it's rare the work gets done. So taking "days off" essentially means just doubling the workload when you get back. This happens from time to time when the faculty organise trips and whatnot and we get some kind of quasi-days off where some classes are "cancelled" bit we still have to cover the same curriculum when we get back. I know I'm blessed when it comes to the amount of consecutive days off I have, but it is a bit of a pain never being able to take a trip when I want to without a massive effort (and no pay, of course).
