Amazon said Tuesday that it will lay off about 14,000 corporate employees, marking the latest cuts in the company’s multi-year effort to rein in costs.

In a blog post, the company wrote that the layoffs are being carried out to help make the company leaner and less bureaucratic, while it looks to invest in “our biggest bets” including generative artificial intelligence.

“This generation of AI is the most transformative technology we’ve seen since the Internet, and it’s enabling companies to innovate much faster than ever before (in existing market segments and altogether new ones),” Beth Galetti, senior vice president of people experience and technology at Amazon, wrote. “We’re convinced that we need to be organized more leanly, with fewer layers and more ownership, to move as quickly as possible for our customers and businesses.”

The layoffs are expected to ultimately be the largest corporate job cuts in Amazon’s history, CNBC previously reported. Reuters reported the cuts could affect as many as 30,000 employees, citing sources familiar with the matter.

Amazon is the nation’s second-largest private employer, with more than 1.54 million staffers globally as of the end of the second quarter. That figure is primarily made up of its warehouse workforce.

It has roughly 350,000 corporate and tech employees, meaning the 14,000 job cuts represent about 4% of that segment of its workforce.

The company indicated that it will continue to lay off employees in the coming year, even as it plans to keep hiring in “key strategic areas.”

Amazon CEO Andy Jassy said in June that the company’s workforce would shrink further as a result of it embracing generative AI, telling staffers that it “will need fewer people doing some of the jobs that are being done today, and more people doing other types of jobs.”
