Tabitha (also an alias), who works for a record label in Los Angeles and uses a company-provided BlackBerry, is a bit more stringent with her after-hours e-mail checking. She's enacted what she calls her "15-minute rule."
"I do an extra 15 minutes or so a couple times a week, max," she said. "It's usually when I'm working on a big project. They're time-sensitive, so I end up checking my e-mail after hours to see if somebody responded. At the record label, a lot happens between 6 p.m. and 9 a.m., and I like knowing what everyone is going to be talking about the next day."
Thirty unpaid minutes a week may not seem like a lot -- until you multiply that by 50 weeks and realize you're giving away 25 hours of work a year. For the full-time, $20/hour employee, that's $500 in gross pay sacrificed.
My advice to those giving their employer 30, 60 or 90 free minutes a week so they can keep up with the workload? Track your off-the-clock efforts, and make sure you leave the office early once in a while to make up for it. Don't settle for the short end of the digital stick.
