From the description: > The concept used is the total number of hours worked over the year divided by the average number of people in employment. The data are intended for comparisons of trends over time; they are unsuitable for comparisons of the level of average annual hours of work for a given year, because of differences in their sources. Part-time workers are covered as well as full-time workers.

So if say, the average South Korean man works 2500 hours (full time, crazy hours) and the average woman works 1000 hours (pretty crazy part time job) - the average would still be below 2000 hours.

I suppose one of the more interesting numbers would be total hours worked vs total work force (including unemployed) - it might be that eg Greece could maintain current productivity (or more likely increase, due to less strain pr worker) by going to a 6 hour work day and ~full employment.
