In Canada, there is the concept of sabbatical accrual (https://ett.ca/know-your-rights-self-funded-leave-plan/). When my wife & I were backpacking in Patagonia we met a Canadian teaching couple with their two children doing the same thing, except instead of one week (us) they were on a 6mo trip from the southern tip of South America up to Alaska.

Then, the same year, we were visiting family in Grenada and met a young family (teachers) with a 4yo on a 40' sailboat they were cruising around the Caribbean on.
