In the future, you may not have to work at the office, but that doesn’t mean you won’t have to work as much. That’s the upshot of a report released by staffing firm OfficeTeam. The firm’s “Office of the Future: 2020” study concluded that the future office will be increasingly mobile, with technology enabling employees to perform their jobs from virtually anywhere. But 42 percent of executives polled in the report said they believe employees will be working more hours in the next 10 to 15 years. Only 9 percent said employees would be working fewer hours.
