Americans say a work day lasting 7 hours or less is most productive, according to a recent poll from YouGov. In total, 52 percent of those polled felt the most productive length of a day in the office
was under seven hours. Broken further, 15 percent felt they were most productive when putting in a daily grind of six hours while 5 percent said 5 hours.
Americans work an average of 8.7 hours every day, putting in a 1,788 hour shift each year. Even though this may seem extremely long, Americans actually trail other developed countries in annual average working hours
. Mexicans and South Koreans work 2,237 and 2,163 hours every year respectively.
