Gartner’s latest survey of 350 executives from billion‑dollar firms that are deploying AI agents, automation, and digital twins reveals a striking paradox: 80 % have trimmed headcount by up to 20 % yet have seen no measurable improvement in financial returns.

The study, released on June 10 2026, shows that companies cutting the most employees performed on par with, and sometimes below, those cutting the fewest. The data suggest that workforce reductions are being used as a quick way to free up budget, but the expected efficiency gains are not materializing.

Two high‑profile examples illustrate the cost of rapid layoffs in the name of AI. Klarna, the Swedish fintech firm, eliminated 700 customer‑service roles in an effort to replace them with an AI assistant. The move eroded service quality, forcing the company to rehiring staff. IBM similarly automated large portions of its human‑resources functions, only to reverse the decision when the system could not handle the nuanced judgment calls required in HR.

Jaime Raul Zepeda, EVP of Best Companies Group, argues that the disconnect stems from a lack of training and change‑management practices. “Companies are buying subscriptions to models such as Anthropic’s Claude and deploying AI agents into workflows without accompanying programs to teach managers and employees how to work alongside the technology,” Zepeda said. He added that “technology adoption has never been a technology problem. It’s a people problem.”

Zepeda points out that the most successful organizations treat AI as a high‑performing new hire: they onboard the system, train staff to collaborate with it, redesign workflows so that humans and the tool each perform their strongest tasks, and implement a structured change‑management plan. In contrast, firms that cut staff first and then introduce AI often find that the technology does not deliver the promised productivity gains.

The survey also indicates that the current wave of AI adoption is still in flux. While AI capabilities are advancing rapidly, the evidence from Gartner’s data is early. The lack of return gains associated with workforce reductions suggests that companies need to focus on integrating AI into existing processes rather than using it as a shortcut to cut jobs.

In summary, the Gartner survey shows that 80 % of companies deploying AI agents, automation, and digital twins have reduced headcount without improving financial performance. Companies that reversed layoffs, such as Klarna and IBM, demonstrate the risks of replacing people with AI prematurely. The findings underscore the importance of training, change management, and thoughtful workflow redesign in realizing the benefits of AI. As AI technology continues to evolve, organizations that invest in their people and in effective integration strategies are likely to maintain institutional knowledge and competitive advantage.
