How could you possibly have a work-free day? Who'd drive the bus taking voters to the polling place? Who'd be manning the emergency room at the local hospital, or driving the ambulances, or enforcing the law, or keeping the power plant running, or spotting for forest fires, or... I love the concept of a "work-free day", but I'm guessing that something like 5-10% of the workforce is doing infrastructure stuff that needs, absolutely needs, to happen every day simply to keep society functioning.
