By far, workers in South Korea have the longest work hours in the world. The average South Korean works 2,390 hours each year, according to the OECD. This is over 400 hours longer than the next longest-working country and 34% more hours than the average in the United States. A typical workweek in South Korea is 44 hours or longer. Most people start their day at 8am and end at around 7pm or later, often having dinner before returning to work. Until legislation in 2004 that virtually abolished the six-day workweek in large corporations known as “jaebol”, South Korea was the only country in the OECD that worked Saturdays.[5]
Work hours in Japan are decreasing, but many Japanese still work long hours. Recently, Japan’s Ministry of Health, Labor and Welfare (MHLW) has issued a draft report recommending major changes to regulations that govern working hours. The centerpiece of the proposal is an exemption from overtime pay for white-collar workers.
South Korea and Japan are the only countries where death by work or “karoshi” (과로사) is a recognized phenomenon.[6]
