Earlier quoted context omitted.
I wouldn't say "behind" in that context. I do appreciate the convenience of 24h stores, but I don't see them as a progress for workers rights.
If the owner of a store wants to open it for 24 hours and he or employees are willing to work, how is that bad for workers rights? What’s bad for workers rights are people that would like the freedom to work a late shift or early shift but can’t because some do-gooder is trying to “protect” grown adults from making their own decisions.
That would be fine, but what is going to happen is that many workers will have to work night shifts unwillingly. It's bad for their physical and mental health.
Suppose you have a town with two stores. First store is willing to open 24 hours. Second store may have to do the same to compensate the loss of customers, and the workers there may have to work night shift even if they don't want to (I actually witnessed it first hand in my neighbourhood).
This is called a negative externality, and it is a well-known defect of free market. Even though you would think that opening a store 24h only impacts you and your customers, it negatively impacts other people.
This is a subjective opinion, but I would argue that the convenience of having 24h stores isn't worth the cost for the workers. Unfortunately, I think that I'm in the minority and that eventually we'll cross that line in Europe too, and it'll be hard to go back.
