The 40-hour work week is a staple of American working traditions, as much as coffee breaks and water cooler conversation.
It was originally implemented by Henry Ford and the Ford Motor Company as a way to protect workers and ensure their productivity.
It's been the gold standard for blue-collar workers since the early 1900s and continues to be the norm today.
The US Bureau of Labor Statistics finds the average American worker labors for 44 hours each week, or just over eight hours per day.
How do foreigners compare?
But how do other countries measure up? Do Americans work more or less – and more or less efficiently? – than their international counterparts?
In Mexico, the mandatory work week is 48 hours per week, or 2,246 hours per year. There are some loopholes that prevent national law from being fully implemented, however, and some private-sector employees can elect to work longer hours without the benefit of overtime compensation.
South Korean workers clock in for an average or 2,113 hours per year, divided up into five working days.
They enjoy 16 public holidays per year and companies are prohibited by law from making workings toil for more than 16 hours worth of overtime on weekends.
How is time spent?

The Department of Labor also found women spent more time on housework; 2.6 hours to the average man's 2.1 hours daily.
The average American man works about 44 hours per week and the average American woman works about 41 hours per week.
