Many nights, the e-mails from his boss arrived between 2:30 and 4:30 a.m. — "no man's land," in Michael Bodnar's words.
"I wouldn't know if he was starting his workday wicked early, or if he hadn't gone to sleep yet — or if he never slept," said Bodnar, a data center manager from Ashland, Mass.
"He used it to strategic advantage," said Bodnar, who has moved on from the vampire boss but remains agitated at the memory. "He would draw you into something in the middle of the night. He'd plant a seed of doubt."
Even as some U.S. firms boast about policies that encourage workers to unplug — allowing unlimited vacation time, for example, or discouraging after-hours e-mails — many workers like Bodnar say they are afraid to go offline. The employee who sleeps through a 3 a.m. e-mail risks losing out on business.
If only they lived in France. Last month, labor unions and corporate representatives there agreed to limit after-hours e-mails. The agreement, which would give workers an 11-hour e-mail-free window, aims to improve work-life balance. Word of the French e-mail limits went viral in the United States, where work is increasingly encroaching on the rest of life, one message at a time.
More than four of 10 cellphone-owning adults have slept near their phones so that they don't miss a text or an e-mail, according to 2012 data from the Pew Internet Project.
Statistics on the volume of late-night work-related e-mails are hard to come by, but one thing is clear: Middle-of-the-night e-mailing is a source of stress — on both sides of the "send" button.
Consider Liz Cohen, executive director of Families First Parenting Programs in Cambridge, Mass., and a bad sleeper. She's also a boss who often sends e-mails at 3 a.m.
