This is also true to a similar degree to how the US defines it. It's an important point, since a lot of people are arguably underemployed, but are still included in employed statistics. I just didn't want to get too far into the weeds of the definition and distract away from the point of how unemployment excludes people while employment does not.
Surely there's a Full Time Equivalent (FTE) employment definition somewhere to capture exactly this issue. But if there is, it never seems to come up in public discourse, possibly because it is difficult to understand or for people to directly relate to.
