The world’s biggest trial of the four-day week is underway in the UK, RNZ reports, where more than 3300 workers and 70 companies are leaving Monday-to-Friday behind. 4 Day Week Global co-founder New Zealander Andrew Barnes first trialled an extra day off at his Aotearoa company Perpetual Guardian in 2018, and has been doing it ever since, citing increased productivity and happier employees. “Once you eliminate a lot of the busyness that impacts companies and employees, you find that actually productivity goes up,” Barnes says.
