Americans don't know how to take time off:
Western European laws require at least ten and usually more than twenty days. And it’s not just the slacker Mediterranean countries. The nose-to-the-grindstone Germans and Austrians require employers to grant at least twenty paid vacation days a year. In the United States, some of us don’t get any vacation at all. Most American workers do get paid vacations from their bosses, but only twelve days on average, much less than the state-guaranteed European minimum. And even when they get vacation time, Americans often don’t use it.
Perhaps Americans are Protestant-ethic work obsessives; we are likelier than Europeans to say that we want to work more hours than we do. But this leisure gap is a recent development. In the 1960s Americans and Europeans worked about the same number of hours. Leisure time then expanded everywhere—only more slowly and much less in the United States than elsewhere, leaving today’s disparity.
A recent study found that the average American works an extra 365 hours a year because of their smartphones.
