Some countries have a work ethic that makes the US workweek look like a walk in the park.

The average US workweek is 38.6 hours long. That may feel like forever to some people, but it's nothing compared to some countries' workweeks. According to a 40-country annual survey by the Organisation for Economic Co-operation and Development (OECD), the international average workweek was 36.8 hours in 2018. We looked at the OECD's Better Life Index to find out why workweeks were so long in some places, but not in others.

Next time you're feeling envious of the Dutch workweek (at 29 hours long on average, it's the shortest on the OECD's ranking), remember that some workers spend a lot more time at the office than you do.

Here are the countries with the world's longest workweeks.
