Most of the public might not know what PR is all about, but we can spot the symptoms: we stay open longer than the corner deli, dealing with insane work weeks in which we have to be ready to address clients’ problems at any moment, whether we’re sitting at our desks or catching up on our DVR queue. We frequently turn down Friday night invites because we don’t have the energy to do anything but crash after five hectic days. Oh, and don’t even mention weekends…

For these reasons, most people in PR will identify with a study, covered in the Harvard Business Review, that paints a picture of a professional class that’s pretty much always on the job.

The survey of “executives, managers, and professionals” found that a majority of those who use smartphones for work (that’s all of us) are “connected” to their jobs for approximately 13 1/2 hours each weekday and 5 hours each weekend for a grand total of 72 hours. Yep, we’re on call for a majority of our waking hours.

So tell us, PR professionals: are you ever really “off the clock”? How many hours do you work in an average day/week?
