The opposite is also true - don't imagine a 1930's production line factory or bank clerk as the reality of a majority employee population working day.

Farmers, truck drivers, pilots, bakers, hospitality workers, nurses, street sweepers, security guards and a thousand other jobs are NOT bound to a 9-5 working time. Indeed, outside of government or large corporations, I struggle to find many professions that ARE bound (or have to BE bound) to these hours.
