When are people going to learn? Many folks act as if e-mail is akin to a verbal conversation that comes and goes in the wind. Yet e-mail has a degree of permanence that hardly ever dies.
Recent history is crammed with examples of e-mails that later became the bane of their authors’ existence. Once revealed, a poorly worded e-mail or an e-mail that should not have been sent in the first place can cause much embarrassment. That’s the best-case scenario. The worst-case scenario? Try civil liability and even criminal prosecution.
