I don't know exactly where they are pulling those numbers from; but last time I checked, reports of average working hours around the world were averaged over everyone, even part-time/temporary/seasonal workers. So the average for full-time workers is much higher, and the average for part-time workers is lower. The overall average is useless for anything other than loose comparisons between countries.

As a South Korean, my impression is that full-time workers in desirable positions tend to put in around 2,500 hours per year. We recently introduced a new law that puts a hard limit (for any given pair of employer and employee) of 52 hours per week, averaged over a 3-month period. There's been a lot of pushback from businesses that either require or encourage working even more hours.
