Be smarter at work, slack off
`”The physiological effects of tiredness are well-known. You can turn a smart person into an idiot just by overworking him,” notes Peter Capelli, a professor of management at Wharton.
Still, putting in more than 50 hours a week at the office has become routine — and that doesn’t count time spent doing paperwork at home, answering e-mail at the airport, or talking on the phone in the car.
Sooner or later, companies’ performance has to reflect that, Capelli says. “On the organizational level, what you get is, everyone is so focused on running flat-out to meet current goals that the whole company is unable to step back and think.”‘
