What? No one said anything about taking away breaks. People work Saturday and Sunday and take their breaks during the week.
Maybe that's why I live in France :-).
Fortunately, here in Italy, Mario Monti got rid of some of the rules about working on Sunday.
It is impossible to mandate that nobody work on any of the 7 days, because hospitals. So we already admit that some people will be working when most people are not - the question is whether we tell them to suck it up, society is going to ignore them forever, or whether we can re-arrange society so that the family of the ER doctor can also work Sunday and take Wednesday off to be together.
