Yes, there are laws that govern this. My point is that the person I was responding to was implying that only he, as the owner, and the customer were affected by his choice to be open. The effects are much larger than just him and the customer. So it is not a ridiculous argument as such. What works in practice will vary quite considerably to your idealised view. I have worked for such owners and was glad to see the last of them.

Irrespective of any laws that are in place, there are still many owners who will threaten sackings if people do not obey the owner's whim and decisions as to the hours the employee is to work. If that means that the employees are expected to be there 7 days a week then there are many owners who will sack their staff for only wanting to work 5 or 6 days a week. There are many employees who do not feel that they have any control over this and simply comply because they feel powerless and locked in. But that is a side issue here.
