14% of the Dutch have burn-out symptoms (1 out of 7) according to:
Dutch newspaper: https://www.volkskrant.nl/de-gids/hoe-opgebrand-is-nederland... which cites : https://www.volksgezondheidenzorg.info/onderwerp/overspannen...
Note that having burn-out symptoms is not equal to 100% burn-out and unable to work.
That sounds accurate, because a report released just this week found that about a third of all Americans suffer burnout in their jobs[0]. At least the Dutch are doing something about it.
