I'm a fan of being connected. Obviously. And I bought a Palm Treo 650 years ago so I could stay up on my work email when I'm away from my computer. But I've found that constant access to my email stresses me out. Do I really want to know there's a problem with a project when I'm about to enjoy a movie? Is there some reason I can't get that e-mail in the morning?
According to a recent study by MIT's Sloan School of Management, I'm not alone. By looking at BlackBerry use at a certain company, the study found that constant e-mail checking led to more stress. According to the study, 90 percent of subjects claimed they felt "some degree of compulsion," checking their e-mail on nights, weekends, at church, at the gym, and even when they were out socially.
The study also found that the problem stems from managers. Once higher-ups start compulsive e-mail checking, everyone else follows suit till it becomes normal that someone will get back to you at any hour of the day.
