Amazon’s Tracy, California, warehouse uses fleets of robots to move and sort stock, while more than 3,000 people still work alongside them. Business Insider’s account shows the immediate change: less walking and cart-pushing for some workers, more monitoring, maintenance and troubleshooting for others.

What happened
At the 1.4-million-square-foot site, Hercules robots bring inventory pods to workstations, while other machines sort parcels and move carts. Workers still pack orders, load trailers, deal with damaged or misrouted items and intervene when machines fail.
Business Insider describes employees moving into roles supervising robot fleets and responding to faults. One worker, Briana Brager, moved from picking to coordinating responses when robots stop or chutes jam, after two weeks of intensive training and further job shadowing.
Amazon told the publication that the Tracy site employs more than 3,000 people, up from roughly 1,000 when it opened in 2023. The company says its more automated fulfilment centres are about 25% more productive, process orders up to 25% faster and support roughly 30% more skilled jobs. Those are Amazon’s figures, not an independent comparison.
Why it matters
The warehouse is a useful case study in the less tidy version of automation: machines take over particular tasks, while people handle exceptions, keep equipment running and do work the systems have not replaced. Amazon manager Mohammed Khan estimated one Robin sorting robot could do roughly the work of two to seven people performing that task manually. That does not tell us the net effect on employment across the business.
The site’s reported headcount has grown, but Amazon says rising customer demand drove that growth. It is not evidence that robots created the additional jobs, or that similar outcomes will follow elsewhere. The more immediate question is whether the new roles are accessible to workers whose old tasks are automated, and whether training and pay make the move worthwhile.
Our read
This is a more grounded picture than either “robots take every job” or “automation creates better work for everyone”. People remain essential at Tracy, but the work is shifting, and the company’s productivity claims do not settle what happens to jobs across the wider network. The detail worth watching is who gets trained, who moves up, and who is left with fewer hours or fewer routes into work.
What to watch
- Whether Amazon publishes comparable staffing and job-role figures for more automated sites.
- How many workers move into technical roles, and what training and pay those jobs require.
- Whether the work still done by people changes as Amazon develops Project Tetromino, an AI-and-robotics effort to automate sorting and vehicle loading at delivery stations.
Discussion spark: When robots take over physical tasks but workers move into monitoring and maintenance, what evidence would convince you that the change has improved workers’ prospects rather than simply shifted the risk onto them?
