Let’s see: 150 years back, the work day was often 12 hours or more, you worked six days, maybe five and a half if your employer was progressive and only worked half days on Saturday.
Store clerks often worked the entire time a store was open which might be from seven in the morning until ten at night.
No, I think this guy has got this one so badly wrong as to be laughable. This smells of being locked in an ivory tower for so long you have forgotten the real world entirely.
No one is forced to work an 8 hour day, I understand there’s lots of part time work out there and even day work where you don’t even have to show up tomorrow. Go wild.
