Are you an off-shore contractor working for a US company? How do you really feel about working US Hours?

I have several contractors on my team who say "I'm willing to work any shift" but I need you to be honest with me on devRant... how do you really feel? Do you have families? Do you prefer to work your normal hours? Why do all of my contractors martyr themselves to work whenever they think makes me happy?

I can work around your requests, I'd probably get better work if you're happier and well rested. I'm not sure what I'm missing, are these hours actually better for you and your family?
