WHO HAS THE HIGHEST NUMBERS OF HOURS WORKED PER PERSON BY AN OECD - MEXICO TAKES NUMBER 1 WITH 2237 HOURS WORKED PER YEAR FOLLOWED BY S KOREA RANKING SECOND WITH 2163 YEARLY HOURS WORKED, GERMANY WAS 1388HOURS, JAPAN WITH 1735, AND THE USA 1788 HOURS

Koreans still work almost the longest hours in the world, according to the latest statistics.
Per-capita annual labor data compiled by the OECD shows Koreans working 2,163 hours a year, second only to Mexico's 2,237 hours.
The thrifty Dutch had the shortest annual work hours at 1,380, followed by Germany's efficient 1,388 hours, Japan's 1,735 and the U.S.' 1,788 hours.
But Koreans are not particularly productive in all the time they spend at work, suggesting that more leisure might improve their focus.
Experts have long been saying that Korean businesses need to change both their corporate culture and wage system. The focus of performance evaluations must shift from hours logged at the office to tasks accomplished. Simply clocking in at 8 a.m. and working until 10 p.m. without focusing on the quality of work does not seem to improve productivity.
