Americans spend most of their day--and in some cases--their evenings--in
the office. In fact, according to a Gallup poll, Americans clock in
more office hours than any of their global counterparts. Full-time
workers average about 47 hours per week in the office, which equates to
just about six days a week. And nearly four in 10 workers said they do
50-plus hours in the workplace weekly. But working all these hours might just be counterproductive, say experts.
