They're talking about two different things - one is about people leaving the labor force entirely, whilst the other is about people quitting their current jobs. Now, there might be some overlap but there doesn't necessarily have to be all that much because a bunch of people were made redundant earlier in the pandemic and some of them aren't going to return to working again.

Yep, it's a bit crazy how most Western school systems I'm aware of are still designed like it's the 80s and every household has a parent at home full-time.

E.g., school finishes early afternoon, large amounts of school holidays that dramatically exceed the annual leave entitlements of two parents combined, etc.
