Nope, but I was a truck driver, and worked with other truck drivers for the last 30 years. Any truck driver that steals time (more than a few minutes here and there) and takes naps when he knows he shouldn't will never change. I retired from UPS's LTL freight division and UPS is the King of employee surveillance. Millions and millions spent on DIADs, Telematics, supervisors physically following drivers, etc. Now and then it did weed out a bad employee, but what it did every day was breed hatred and distrust of Big Brown by all involved. So, if you're just concerned about this one guy have somebody follow him for a day. He'll fuck up.
