Sure, you can set an out-of-office auto-reply to let others know they shouldn't email you, but that doesn't usually stop the messages; you may still have to handle those urgent-but-not-really requests while you're on vacation. That's not a problem if you work at Daimler, though. The German automaker recently installed software that not only auto-replies to email sent while staff is away, but deletes it outright. If there's a meltdown at the workplace, you may not have to deal with it at all. The move affects about 100,000 employees, so it's clearly going to make an impact.
