Amazon’s robots work hand-in-hand with human employees

Company's fulfillment centers rely heavily on automation, raising concerns

PHILADELPIA — Amazon employees start their shifts passing through turnstiles and a sign reminding them what they can’t bring with them as they report for work alongside robots.

Cellphones, belts, keys and loose change must be stored away in one of hundreds of lockers by the break area at the West Deptford, Pa., fulfillment center. Inside, 7.75-inch-tall robots that can carry up to 1,250 pounds and have no resemblance to the humanoid robots of science fiction help them do their jobs.

The robots — effectively shelves on wheels — zip around at 5 feet per second inside a large cage on the second and third floors of a warehouse the size of almost 30 football fields.

While Amazon hires tens of thousands of people in the process to staff warehouses like the one opened in September in Gloucester County, Pa., the Seattle-based company is also embracing automation and deploying robots to do work once done by humans. Critics and labor advocates worry that automation could replace human workers and that the machinery-rich Amazon warehouses are an unsafe working environment.

“It’s not humans vs. machines at all,” Tye Brady, the chief technologist at Amazon Robotics, told the BBC this month. “It’s humans and machines working together to achieve a task.”

Amazon has grown rapidly, from 20,700 employees in 2008 to 647,500 full-time and part-time employees in 2018. In West Deptford, the company said it has more than 1,500 full-time employees and uses more than 3,000 robots.

Amazon’s net sales increased 31 percent in 2018 to $232.9 billion and its net income more than tripled to $10.1 billion.

“Despite these vast resources,” a report from the National Council for Occupational Safety and Health states, “there is little evidence the company has made a significant effort to address worker complaints about stress, overwork and other conditions which can lead to illness, injuries and even fatalities.”

Six workers have died at U.S. Amazon facilities or operations since November 2018, and 13 workers overall have died since 2013, according to the report.

Amazon insists that its facilities are safe and that increasing automation does not mean it will hire fewer people.

A 2017 report from McKinsey Global Institute estimated that automation could displace up to 800 million people globally by 2030, even as it acknowledged that automation can create jobs.

‘Little race cars’

Items from Amazon or vendors make their way into the West Deptford facility on a conveyor belt and travel to the second floor where “stowers,” such as Lisa Bailey, 51, of Camden County, work.

She stands outside the cage of robots and scans products ranging from Amazon Fire Sticks to pretzels to Ziploc bags. The robot carrying a shelf full of cubbies waits patiently as Bailey fills it. Other robots are moving around behind it, traveling close to each other, but never colliding. Once Bailey finishes, the robot whisks the shelf away.

“They look like little race cars,” Bailey said on Friday inside the air-conditioned facility.

In the second-floor station next to Bailey, David Grieco, 45, of Lafayette Hill, is a “picker.” He follows instructions on a computer screen while removing items from the moving shelf, now paused in front of his work station. He scans items and places them in yellow plastic containers on a conveyor belt.

Those containers travel down to the ground floor, where Tyleira Thompson, 22, of Sicklerville, “a packer,” puts the items into the cardboard boxes that will arrive on a customer’s doorstep.

After taping them shut, Thompson places the cardboard boxes on another conveyor belt that takes them under a machine that sticks on the shipping labels before they go out into the loading zone, where trucks are filled for deliveries throughout the Northeast.

In cities such as Houston, Salt Lake City, Tampa, Fla., and Sacramento, Calif., employees are doing the same work alongside robots.

The general manager of the West Deptford site, Roberto Miller, said the robots do monotonous tasks so employees can have more engaging jobs. While a human may have needed to lift heavy boxes before, now a large robotic arm does that work and the employee may work as a machine operator.

The West Deptford site is Amazon’s fourth robotic fulfillment center in New Jersey, the company said. Amazon launched its operations in the state in 2012 and now employs more than 17,500 full-time statewide.

Amazon has been in Pennsylvania since 2008 and said it has more than 10,000 full-time employees across the state.

Amazon continues to hire, and has more than 150 openings in New Jersey, the company said.
