South Korea
South Korea has the fastest shortening working time in the OECD,which is the result of the government's proactive move to lower working hours at all levels to increase leisure and relaxation time, which introduced the mandatory forty-hour, five-day working week in 2004 for companies with over 1,000 employees(although, confusingly, total legal working hours is still 68 hours per week: it is legal to demand 12 hours of overtime during the week(often included in the '40-hour contracted salary' for office staff, plus another 16 hours on weekends). This expanded to companies with 300 employees or more in 2005, 100 employees or more in 2006, 50 or more in 2007, 20 or more in 2008 and a full inclusion to all workers nationwide in July 2011.The government has continuously increased public holidays to 16 days in 2013, more than the 10 days of the United States and double that of the United Kingdom's 8 days.Despite those efforts, South Korea's work hours are still relatively long, with an average 2,163 hours per year in 2013.
