A video game studio moved to a four-day workweek. It 'saved us,' employees say.

The idea of the four-week workweek is not new. Louis Hyman, a historian of work and business at Cornell University's School of Industrial and Labor Relations, explained that the current five-day workweek composed of eight-hour days was born of factory worker strikes in the 19th and 20th centuries, as well as nationwide union strength in the years following World War I. After workers pressured the likes of Henry Ford and eventually the United States government to adopt the five-day workweek, there were widespread calls for a four-day workweek. Recently, the concept has resurfaced. Companies as large as Panasonic have implemented versions of it, as have video game studios like "Guardians of the Galaxy" developer Eidos-Montreal and indie studios Vodeo Games and KO_OP.
