That's a different issue. Whenever I hire a contractor, I am concerned about references. Whether he has a reputation for quality work is important -- much more so than who his workers are. My Salvadoran landscaper does excellent work -- so much so that half the homeowners on our street now use him, and the other half wish he had time to take on more customers. AND, when Hurricane Isabel slammed into Annapolis two years ago, and I had to have A LOT of yard work done, my homeowners insurer raised no questions about his work or his rates.
Did you read what I posted?

I'm done here.
