< So I ask you again: in your opinion, would a seven day week be a good thing or a bad thing? >
For people that choose to work 7 days a week, it would be a great thing, they will be allowed to exercise their constitutional rights.
For people that don't want to work work 7 days a week, all they have to do is simply not take a job that requires them to work 7 days a week.
Currently we have a nonstated generally-accepted 5 day a week workweek, that doesn't mean that everybody in the country right now is working 5 days and only 5 days a week. If some employees want to work 7 days a week for straight time (if the OT unconstitutional laws were repealed), that is not going to force everyone to work 7 days a week, and we know that is the case because currently there is a disparity of the number of days worked by employees, some work 5 and some work 3, the disparity will not be removed if the OT laws are removed.
Except that wouldn't be the choice. Any more than people have the choice to work every other minute now. Just as has already happened before (see "Century, the 19th") the absence of safe guards will generate a competitive market dynamic that will lead to 7 day weeks. Would it be better than the status quo for a majority of American workers to work 7 day weeks? Yes or no?
