Americans have mediocre work spaces, slack off 40-hour weeks

42% of office workers graded their work space design a C. Another 10% rated their cubicle or office a D, and 4% gave it an F. Only 6% gave their space an A. Logitech this week released the results of the study, which surveyed 1,003 U.S. office workers. Those surveyed spent an average of 37.5 hours a week in their workspace, whether in an office, cubicle or shared space, according to the study. In all, office workers gave their respective spaces a 2.3 grade point average, the equivalent of a C+, Logitech said.
