Do you check your company e-mail from home before you go to bed or in the morning with your first cup of coffee before you shower? Do you commute via public transportation and work on your laptop during the trip? Do all your calls forward to your cell phone? Do you know where your desk phone is, or do you even have one? It's both a blessing and a curse that technology lets us work from anywhere, any time. Digital devices can extend the workday and blur the boundary between professional and personal lives like nothing ever has.
