Workers fear AI most when they use it without seeing a productivity gain

Workers appear most anxious about AI not when they avoid it or master it, but when they use it without seeing a clear productivity gain. Federal Reserve Bank of Boston analysis found that the share worried about losing their own job to AI nearly doubled from 5 percent at the end of 2024 to just over 10 percent at the end of 2025. A much larger 60 percent expected layoffs or fewer workers across their industry. The most revealing result was hump-shaped. Workers who strongly agreed that AI made them more productive had an estimated 6.1 percent likelihood of job-loss concern. Those neutral about productivity gains had a 21.2 percent likelihood and were also the most likely to report new, unmanageable expectations. Highly productive users were more likely to consider asking for a raise, but they represented only 6 percent of the regression sample. The findings are survey perceptions, not causal proof that AI created productivity, fear, or wage pressure. They still identify the adoption middle as the place leaders should examine. Employees can be required to use tools, surrender parts of their workflow, and face higher output targets without receiving better training, credible measurement, more autonomy, or a share of the gain. Workforce strategy should track usable output, rework, workload, bargaining outcomes, and team staffing, not licenses and prompts. AI adoption becomes durable when workers can see the value, influence the workflow, and trust that efficiency will not simply become an unreasonable target.
