Oh yea for sure, but people used to basically have to work around the clock 7 days per week with no breaks or reprieve before the labour movements interceded and fought for that 40 hours.

The 40 hour is still exploitation, but imagine how back-breaking weekly schedules were before!

Always remember, capitalists will give the worker as little as they can get away with for the most grueling work situation that can get away with enforcing.
