Surprise, surprise! The average American worker slacks off about 1.7 hours per work day. Almost half of them spent this time unproductively on the Internet (sorry, guys! I know Neatorama's not helping your productivity!), 1/5th socialized instead of worked, and the rest ... Oh, I'll finish this post l8r.
Useless meetings, conference calls, video conferencing.
Useless training (especially safety).
Endless reports that never get read (or acted upon).
And the biggie - how many hours AFTER the employees shift do the employer nag them via email/text/voice?
