Tech leaders say AI means less work - their staff say they work up to 90 hours a week

For years now, executives at companies that are pouring hundreds of billions of dollars a year into developing various artificial intelligence tools have insisted that the technology will ultimately mean people will spend less of their time working.

An engineering director at Google said four years ago that AI would deliver a four-day work week by 2025, external.

Earlier this year, and just one year after that engineering director's prediction, OpenAI took up the challenge, in a manner of speaking. It formally urged companies to start testing out a four-day work week (with no change in pay), claiming that AI will soon be able to speed up so much human labour that the corporate world should prepare itself.

However, a former OpenAI technical employee who left the company last year told the BBC the firm never actually trialled the four-day work week it suggested others should try while they were there.

Instead, the person described what was often a gruelling work culture marked by frequent "crisis meetings", working on weekends, and "super cut-throat" performance reviews that would see colleagues suddenly let go.

"You go in on Saturday or Sunday just to catch up or make sure things aren't broken," the person said.

Other companies have also pushed the idea that AI will effectively reduce the number of hours people need to work, for better or worse.

Anthropic has boasted that its popular coding tool and chatbot Claude is capable of working on its own for seven hours without a break, external, essentially a full corporate workday. Meta's Mark Zuckerberg has said his company is in the middle of the year when "AI starts to dramatically change the way that we work" and that such tools let far fewer employees do more than they ever could have before.

While Meta has since laid off 1 in 10 of its employees, Anthropic's chief executive Dario Amodei has warned that as AI tools inevitably become more productive, it could mean, external even broader job losses.

Despite these claims, workers inside these same tech companies, who are not only developing but using the very AI tools that will purportedly perform at least some of people's work, say they are clocking in far more than the typical five-day, 40-hour work week.

US tech workers are typically well-compensated, external, and while other industries such as investment banking, law and medicine also often see people work long hours, a 14-hour workday was not always the norm in tech. For years, it was a more typical 9-5 office job.

But the former OpenAI employee said they would put in at least 70 hours a week, much more than they did in previous tech jobs. The person now works at a start-up also focused on AI, and said their work-life balance has improved, working closer to 50-60 hours a week, "outside of sprints".

A "sprint" is term for a common period in technology companies in which people work long hours in the weeks leading up to a release of a new feature or product.

Inside AI companies and larger tech companies working furiously on AI projects, however, such sprints can be extreme.

At OpenAI and Anthropic, for instance, sprints can stretch on for many weeks and top 90 hours of work in a seven-day period, tech workers that the BBC spoke to for this story said.

Neither company responded to BBC requests for comment.

Being 'drafted'

At Meta, workers said they have been abruptly pushed onto teams this year doing AI work being treated as urgent. They called it being "drafted", according to one current and one former employee, because people were not given a choice.

"They just move you over," the former employee said. "You can't say no – or if you do, you have to quit."

They said although Meta recently began to walk back, external that strict take it or leave us approach, by then many workers had already been forced onto such work.

The hours on such teams at Meta are often long, with staff working into the night, on weekends, and feeling they are "on call" during the hours they are not working, according to descriptions of the work from the current and former employees.

There are no limits, external in the US on how many hours a person over the age of 16 can work. In the UK and Europe, for instance, laws limit a working week to 48 hours, including overtime.

Meta's current AI projects include the creation of an AI tool that can be used for software engineering and other kinds of work, and building AI model infrastructure that can measure an AI model's success in replicating various tasks, the employees added.
