JPMorgan Chase boss Jamie Dimon says the use of artificial intelligence will reshape the workforce and eventually lead to a three and half day working week.
Speaking at the America Business Forum in Miami, the CEO said AI will reshape daily tasks across industries, allowing employees in developed economies to work much fewer hours.
“It’s going to affect every application, every job, every customer interface,” he said. He forecasts that within 20 to 40 years, many workers may have “wonderful lives” while working “three and a half days a week.”
The prediction is based somewhat on JPMorgan’s extensive internal deployment of AI. Roughly 2,000 employees are directly building AI tools, and about 150,000 staff use large language models each week to assist with tasks such as legal document review and reconciliation. The bank already has hundreds of AI use cases active across fraud prevention, marketing optimization and internal operations.
Dimon says the shorter week will be the result of cumulative efficiency gains, where repetitive or rules-based work shifts toward automation and requires fewer staff hours to produce the same output.
Transition will require support and reskilling
Dimon warned that the shift will not avoid disruption. Speaking at the Fortune Most Powerful Women Summit, he said: “It will eliminate jobs. People should stop sticking their heads in the sand.”
He argued that companies and governments must plan early for retraining, income support, redeployment initiatives and, when needed, early retirement options to prevent broader social consequences.
JPMorgan, he said, is building its approach with redeployment in mind, placing responsibility on institutional leaders to manage not only technology implementation but also the human impact of workforce transformation.
Six Pillars to Drive Impactful Engagement

AI investment requires selectivity
He also noted that AI infrastructure requires significant capital and energy, and said some projects “won’t get the power they need,” meaning that investors should scrutinize data center and AI build-outs carefully, assessing revenue models and performance risks rather than “buying the theme” outright. Some efforts may exist in a bubble, he said, but overall he believes the technology will probably pay off.
JPMorgan is running AI master classes for senior managers after finding many leaders did not fully understand current tool capabilities. One reaction he cited: “I didn’t know it could read 100,000 documents.”
Dimon concluded by saying employers need to modernize data systems to fully leverage AI: “We spend a lot of money getting data into the proper format… We’re not measuring how much it costs.”
