As a domestic high-tech worker, I can confirm this is true.
I can ALSO confirm that! Sure they work long hours, but they are sloppy as hell, you can't easily communicate with them, and towards the end of any project, some 'natives' have to move in at the last minute to clean up their dammed messes(if they can). The MBAs that make all of the bone-headed decisions don't care though....
I’ll second that.
