AI Fails to Deliver a 4-Day Work Week - Especially at AI Companies (bbc.com) 67

"An engineering director at Google said four years ago that AI would deliver a four-day work week by 2025," remembers the BBC. And earlier this year OpenAI "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... [T]he former OpenAI employee said they would put in at least 70 hours a week, much more than they did in previous tech jobs...

Other companies have also pushed the idea that AI will effectively reduce the number of hours people need to work, for better or worse. [At OpenAI and Anthropic] 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... At Meta, workers said they have been abruptly pushed onto teams this year doing AI work being treated as urgent... 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...

Some new research suggests that AI tools are making people's workloads even more burdensome. A study out of UC Berkeley followed hundreds of workers at a US tech company for eight months as they used AI. It found the employees "worked at a faster pace, took on a broader scope of tasks, and extended work into more hours of the day"... The UC Berkeley research found that the workload of tech employees was expanded in part because of the need to constantly check the output of AI tools.

In the article Neil Thompson, an innovation scholar at MIT, pointed out a problem with estimates that AI will ease the workload on humans. "People assume that 20% less work means four-day weeks. But new work emerges."

The BBC also points out helpfully that "there are no limits in the U.S. on how many hours a person over the age of 16 can work." (While in the UK and Europe, "laws limit a working week to 48 hours, including overtime.")

    The 4 day work week is a logical fallacy. At what point do companies decide to give regular employees more pay for less work? At a time when they don't really need as many employees. That's never going to happen. They have never felt any obligation to share the rewards of productivity.

      I work a 4 day work week. My pay is slightly lower than at my last job, but my hourly rate is higher. My company started offering it years ago because they couldn't compete on salary, but they realized that some of us would really just like a better life, and that was something they could manage.

      The 4DWW isn't as transformative to me as remote work, but it's been so good for me. I'm excited to get back to work on Monday, and I don't ever feel like any part of the week is a slog. I'm happy to occasionally sit down and fix something on the weekend quickly because my brain happened on the answer while I was relaxing.

      If we all must work in this capitalist hellscape, 4 days a week is much more than 20% better than 5.

    The Working Time Directive was instituted in the 1980's. Margret Thatcher was very upset that the UK had to follow this directive to remain in the EU.

    The Working Time Directive limits weekly working time to an average of 48 hours per week over and 17 week reference period. Companies sometimes get exemptions from key employees, but there can't be no coercion to sign such an agreement. The exemptions are usually for key employees.

    Since the UK left the EU, there has been no substantial changes to the regulation. Instead, the original domestic legislation implementing it—the UK's Working Time Regulations—was converted into UK law to maintain legal continuity, and core worker protections regarding maximum working hours and paid holiday remain active

    In contrast to the United States, there is no limit on working time, and the only option the employee has is to quit (Employment-at-will). There are also 2 distinct classes of workers. Those which are non-exempt get overtime pay after 40 hours of work in a week, while those which are "exempt" only get their base salary regardless of how many hours they have to work. There is a dividing line which lists certain job requirements as those falling under exempt, and those which are non-exempt. Managers,Engineers, Accountants, and a lot of indirect labor positions are usually exempt.

    With so many people in the USA living paycheck to paycheck, quitting due to excessive overtime is very unlikely

    • You work as much as your culture and lifestyle dictate. I'm not sure any EU countries standardised on a contractual 48 hour workweek (though frequently by the hour employees tend to work longer), it was a maximum not a target. The actual average across the block is 36 hours. The highest is Greece with an average of 39 hours and the lowest is the Netherlands with 31.9 hours. Virtually no one I know from the Netherlands works 5 days a week. 4 days are pretty normal here.

      • You work as much as your culture and lifestyle dictate.

        I work plenty of hours. I work the number of hours I want to work. Now that does indicate to many people that I am a perfectionist, a once esteemed quality, now widely regarded as mental illness, a negative character trait that needs to be eliminated.And that's okay, it makes me a total beast to compete with.

        There are plenty of people in the US who work as little as they can, if they do just enough to not get fired, they consider that a win. And that's okay - maybe that makes them happy.

        This has nothing to do with AI, it's largely got to do with a culture of not attempting to fuck yourself over to make an extra dollar, something that would be seen as "slack" in the USA. Many people in Europe work to live and do the minimum, not live to work.

        Obviously people on low wages unable to make a living don't have that option, but that doesn't describe many people. I see engineers in our USA offices proudly working 60+ hour weeks. Congrats you earn over $200k, do you have any spare time to spend it?

      While 15 hours per week may be naïve, the premise itself is not.

People used to regularly work 100+ hour weeks. It wasn't until 1938 until America coded the 40 hour work week as a standard in law (60 hours was pretty damn standard before then), and there are already many places around the world where people don't live to work an

    I have never seen adding more computers equate to less workers. Computers are needy, they need regular maintenance sure, but the real gotcha is all the work a computer creates because people are constantly needed to fix it when it goes wrong and still more people to go around putting out all the little fires it causes. AI just accelerates the problem.
