Amazon's Robot Fleet Exceeds One Million, Human Workforce Over 1.5 Million

Amazon's robotic workforce in its warehouses has now exceeded one million units, according to recent reports. This expansion of automation coincides with the company employing more than 1.5 million full-time and part-time workers worldwide, making it one of the largest private employers.

The company states that robots are utilized for tasks such as moving heavy items and retrieving goods from high shelves, aiming to reduce physical strain and risk for human employees. However, labor groups and researchers have raised concerns that increased automation might accelerate work pace and lead to more repetitive motions, potentially increasing worker fatigue and injury.

A study published in the ILR Review journal in April 2025 indicated a 40% reduction in severe injuries at Amazon's robotic warehouses compared to its traditional facilities. This finding supports Amazon's argument that robots are handling the most physically demanding and hazardous jobs. Conversely, the same study documented a 77% increase in minor injuries related to repetitive stress in robotic warehouse environments.

Analyses of employee discussions online suggest that while the physical burden may be lighter with robots, the mental toll can be higher due to faster work paces and more repetitive tasks. Separate reports from 2021 and 2022, based on data submitted to the government, claimed that injury rates were higher in Amazon's robotic warehouses than in non-robotic ones.
