ChatGPT-maker OpenAI says employers should consider trialling a four-day work week as AI use and demand grows in the workplace.

Its "people-first" policy proposals set out a range of ideas to help society adjust to an AI era - something it says will bring benefits but also disruption to our lives and careers.

Among its suggestions were creating more work opportunities in people-facing sectors such as childcare, education and healthcare.

The company said its set of initial ideas - chiefly aimed at the US - aimed to prompt discussions about action needed as AI systems become more capable.

Rapid reductions in the time taken by AI tools to complete some tasks mean a transition to advanced AI is in sight, OpenAI said in its Industrial Policy for the Intelligence Age report.
