CEO Satya Nadella had words of warning for the tech sector after the tech giant joined the growing ranks of companies laying off workers – in his case 10,000.

Nadella made no direct mention of the layoffs on Wednesday when he put in an appearance at the World Economic Forum’s annual meeting happening this week in Davos, Switzerland. The job cuts had been disclosed that same the day.

When asked by the forum’s founder Klaus Schwab on what tech layoffs meant for the industry’s business model, Nadella said companies that boomed during the COVID-19 pandemic are now seeing “normalization” of that demand.

“Quite frankly, we in the tech industry will also have to get efficient, right?” Nadella said. “It’s not about everyone else doing more with less. We will have to do more with less. So we will have to show our own productivity gains with our own sort of technology.”

Among big tech firms, Apple is so far the only one not to announce any job cuts.

“Apple is a major exception: It did not appreciably increase its rate of hiring over the last two years, and also has not announced any layoffs,” CNBC reports.

Microsoft declined to answer questions about where the layoffs and office closures would be concentrated. The company sent notice to Washington state employment officials Wednesday that it was cutting 878 workers at its offices in Redmond and the nearby cities of Bellevue and Issaquah.

As of June, it had 122,000 workers in the U.S. and 99,000 elsewhere.

Microsoft is cutting far fewer jobs than it had added during the COVID-19 pandemic as it responded to a boom in demand for its workplace software and cloud computing services with so many people working and studying from home.  Its workforce expanded by about 36% in the two fiscal years following the emergence of the pandemic, growing from 163,000 workers at the end of June 2020, to 221,000 in June 2022.

“A big part of this is just overexuberance in hiring,” said Joshua White, a finance professor at Vanderbilt University.

White, the Vanderbilt professor, said all industries are looking to cut costs ahead of a possible recession but tech companies could be particularly sensitive to the rapid rise in interest rates, a tool that has been used aggressively in recent months by the Federal Reserve in its fight against inflation.

“This hits tech companies a little harder than it does industrials or consumer staples because a huge portion of Microsoft’s value is on projects with cash flows that won’t pay off for several years,” he said.

Among the projects that have been attracting attention recently is Microsoft’s investment in its San Francisco startup partner OpenAI, maker of the writing tool ChatGPT and other AI systems that can generate readable text, images and computer code.

Microsoft, which owns the Xbox game business, also faces regulatory uncertainty in the U.S. and Europe delaying its planned $68.7 billion takeover of video game company Activision Blizzard, which had about 9,800 employees as of a year ago.

Microsoft’s workforce expanded by about 36% in the two fiscal years following the emergence of the pandemic, growing from 163,000 workers at the end of June 2020, to 221,000 in June 2022.

“While we are eliminating roles in some areas, we will continue to hire in key strategic areas,” Nadella said in a blog post. He emphasized the importance of building a “new computer platform” using advances in artificial intelligence.

He said customers that were accelerating their spending on digital technology during the pandemic are now trying to “optimize their digital spend to do more with less.”

“We’re also seeing organizations in every industry and geography exercise caution as some parts of the world are in a recession and other parts are anticipating one,” Nadella wrote.

Other tech companies have also been trimming jobs amid concerns about an economic slowdown.

Amazon and business software maker Salesforce earlier this month announced major job cuts as they prune payrolls that rapidly expanded during the pandemic lockdown.

Amazon said that it will be cutting about 18,000 positions and began notifying affected employees Wednesday in the U.S., Canada and Costa Rica, with other regions to follow, according to emails from executives. The job cuts, which began in November, are the largest set of layoffs in the Seattle company’s history, although just a fraction of its 1.5 million global workforce.

Also Wednesday, the U.K.-based cybersecurity firm Sophos confirmed it had laid off 10% of its global workforce — 450 employees — on Tuesday. Sophos, known for threat intelligence and detection, was acquired in 2020 by the private equity firm Thoma Bravo for $3.9 billion.

Facebook parent Meta is laying off 11,000 people, about 13% of its workforce. And Elon Musk, the new Twitter CEO, has slashed the company’s workforce.
