Forgive me for sidestepping the larger debate about labor (which should be had), but I think Amazon should offer the option for customers to opt out of Sunday deliveries and put other reasonable constraints on the lengths they will go to serve us.
I'm not Mormon but their community has a practice of not shopping or doing business on Sunday. As long as we as customers demand services on Sundays businesses must stay open and some company will serve us... Instead of attacking this on the supply side we as customers should have the option to demand less. I know they offer small credits for accepting slower shipping but I specifically want to put some constraints on when the people who serve me are asked to work. I also don't want their insultingly small credit for this, I'd rather they plant a tree(s) with the savings.
