French regulators dealt a blow to Amazon on Tuesday, slapping the e-commerce giant with a $35 million fine over what they called the company’s “excessive” monitoring of warehouse workers.

France’s privacy watchdog, the National Commission on Informatics and Liberty (CNIL), said Amazon’s surveillance systems place “continuous pressure” on warehouse employees by closely tracking their productivity down to the minute. This includes monitoring scanning speeds and timing bathroom breaks.

Regulators took issue with Amazon’s so-called “stow machine gun” indicator that goes off when workers are scanning items too quickly. They also cited the company’s requirements for employees to provide detailed justifications for any work interruptions as short as one minute.

In levying the record $35 million fine, the CNIL said these practices violate European Union privacy laws by being overly intrusive into workers’ daily lives. Amazon rejects those conclusions as “factually incorrect” and says the systems are standard practice for the warehouse industry.

But worker advocates cheered the CNIL’s action against a company known for its relentless monitoring of employee productivity.

The fine comes amid growing scrutiny of working conditions at Amazon’s sprawling fulfillment centers. Employees in the U.S. have also complained of punishing surveillance, including constant video monitoring by managers and AI algorithms. With the CNIL’s crackdown, regulators are signaling even one of the world’s most powerful companies is not above the law when it comes to worker privacy protections.
