ROCKFORD (WIFR) -- Ten developed countries with the lowest average work week contain a surprising factor. These countries are all among the top 11 countries in terms of wealth.

The list does not contain the United States. America's average worker puts in about 18-hundred hours a year or 34 and a half hours a week.

The lowest average work week is Germany. At 25.6 hours, Denmark has the highest average wage at nearly $49 per hour. Compare that to the U.S., which comes in an average of just over $30 an hour.
