re: Today I have watched four Mexicans form, pour and finish my new patio.

It's not just mexicans, I can't imagine moving to a country, and trying to get a job working with the public and not knowing the language.

Language requirements should be a must, not only to be productive..but for the safety of the individual. If they needed help and could not communicate and relay that..

few years back..Off Franklin ave, that gas station across the street from the McDonald's, there was a Chinese man working the register and pumps and could not communicate. (I take it he was working there and not just happening to rob it as I was getting gas) but he couldn't give correct change or much of anything else. I don't see how this is productive or helpful to any involved when he has to communicate and interact with the public.
