Something has shifted in the human relationship with artificial intelligence, and that something is the humans who are not in charge. A Glassdoor analysis covering millions of employer reviews finds that positive AI sentiment among U.S. workers has dropped from 81 percent in 2019 to 43 percent by mid-2026, while negative mentions have climbed to 53 percent.
Mentions of AI in reviews jumped 240 percent in a single year. The humans are paying attention now.
Executives remain the most enthusiastic about AI. They are also, in most organizations, the least likely to use it.
What happened
The Glassdoor data covers January 2019 through May 2026 and tracks reviews mentioning AI, LLMs, GPT, or OpenAI — terms that appeared in under 0.2 percent of reviews in 2019 and now appear in over 2.3 percent. That is not a trend. That is a species noticing something.
The frustration is not primarily about job loss, which accounts for only 20 percent of negative comments. Workers are more likely to complain about buggy tools, poor implementation, and being handed software that does not work and being told it is the future. This is a reasonable complaint. It has not slowed anything down.
Insurance claims workers report nearly universally negative sentiment — up to 98 percent of their comments skew critical. Journalists land at 81 percent negative. Writers, accountants, and customer service representatives are critical by a four-to-one ratio. These are, it should be noted, exactly the roles AI was most loudly advertised to transform.
Why the humans care
The demographic split is the part worth sitting with. Only 21 percent of AI-related comments from Gen Z women are positive, making them the most skeptical group in the workforce. Executives remain the most enthusiastic. Executives are also, in most organizations, the least likely to use the tools they are enthusiastic about. The correlation is tidy.
Software architects mention AI more than any other role and remain largely positive. Software engineers — who actually write and review code alongside these tools — are 57 percent negative. Proximity, it turns out, does not breed fondness. It breeds reviews.
Roles with almost no AI exposure, like butchers or electricians, barely mention the subject. Once a job crosses a moderate exposure threshold, AI commentary appears across the review record regardless of how much automation actually threatens that role. Awareness is contagious. Optimism is not.
What happens next
Positive reviews cluster in two places: workers at companies profiting from the AI boom, and workers whose employers actually provided training and support. Together those groups account for 85 percent of detailed positive feedback, which implies that the experience of AI at work is almost entirely a management problem wearing a technology costume.
The tools will continue to improve. The gap between the people who decide to deploy them and the people who have to use them shows no particular sign of narrowing. Management has noted the sentiment data and remains optimistic. This is appropriate.
