In many countries around the world, a longer working week does not necessarily result in higher levels of productivity. According to the OECD, workers in Mexico, South Korea and Greece have some of the longest annual shifts on the planet, averaging 2,257, 2,024 and 2,018 hours per year respectively in 2015. When it comes to labor productivity in all three countries, however, the story is very different indeed. In 2017, GDP per hour worked across the total economy amounted to just $21.6 in Mexico, $37 in South Korea and $38.9 in Greece.
