(CNN) - When it comes to vacation, the U.S. lags behind many other countries, some call us the "no vacation nation." A study by Harris Interactive finds 57 percent of working Americans averaged 11 unused vacation days at the end of last year.
Reasons for not taking time off include too much work at the office and not enough money for vacation.
Unlike many other developed countries, U.S. law does not require companies to offer paid vacation time.
Workers in the UK get 28 vacation days a year, followed by 25 in Finland, France and Greece. With Greece’s serious economic issues, some say, perhaps the old vacation should be put on hold.
Japan allows 20 days for vacation.
