AI should make the 4-day work week possible for millions of workers. The question is whether they’ll use the free time for leisure—or more work

Earthly, a London-founded climate tech company, has had a four-day workweek for over two years now—way before the ChatGPT revolution took the world by storm. Following overwhelmingly positive results in a six-month pilot of the shorter week, Earthly decided to stick with it. 

Its employees are more productive with trimmed hours, and with the addition of AI tools such as ChatGPT earlier this year, the four-day week has felt even more seamless, Earthly CEO Oliver Bolton tells Fortune. Earthly now uses the platform to sift through projects, brainstorm, research and streamline operations overall, which has freed up more time for company staff.
