A four-day working week could become commonplace in the UK as automation, and AI increase workplace efficiency, The Guardian reports, citing data from the Social Market Foundation. The study suggests that a 10% gain in workforce productivity could allow employers to produce the same output with a 38-hour week, assuming pay and employer profits remained the same. Furthermore, concluded that a 30% productivity gain could allow the working week to fall to just 32 hours or a standard four-day working week.  However, the Social Market Foundation also warned that without the right government policies the workforce might not see any benefits. The research called for big companies to be required to report their average profit per employee and to show how this is changing relative to wages. Scott Corfe, the Social Market Foundation chief economist who authored the report, commented, “Robots, AI and big data could dramatically change society for the better, addressing the UK’s productivity crisis and creating more enjoyable work as mundane tasks are automated. If we manage this revolution properly, workers will get new choices, including whether to reduce their working week and having more leisure time.”
