John, you really are willing to open up the worm can aren't you?
If I wanted to make that distinction I would have to go after the TelCo and the CableCo too. The guy who shows up is not usually an employee of the company. They are "trunk slammer" contractors with nothing more than an address the company can mail a 1099 to. I doubt any of these guys are actually licensed. I wasn't even sure the break we gave "utilities" extended beyond the area the NESC controls. We used to give Ma Bell a break because we knew the employee was a well trained union journeyman who was going to work within the bounds of the Bell System Practices book.
Now days everyone is a "contractor", usually unlicensed.
