WATCH: Why Americans Work Around The Clock

Americans have a reputation for prioritizing work over play, often sacrificing personal time entirely in favor of finishing professional tasks. Other countries look at Americans as workaholics, and similarly, Americans often laugh at the European work ethic.

But how did this dichotomy come to be? What is it about American culture that fosters an attachment to work that can often lead to "workplace burnout"? According to economist Daniel Hammermesh, it starts with nights and weekends, two periods of time in which Americans seem to continue working while other cultures have stopped.

Watch what Hammermesh had to tell HuffPost Live about the American work ethic in the clip above.
