FALL RIVER — Hundreds of people flocked to the Amazon job fair here early this month: store clerks, security guards, technicians, an EMT, an iPhone repairman, even a manager at a hospital — some unemployed, many not — ranging in age from teens to retirees. They were lured by the prospect of a full-time job with benefits at a company so successful it has obliterated jobs across the retail landscape.

Amazon the job killer is also creating jobs at a staggering pace, mostly in its massive warehouse and delivery operations. But will there be enough for the workers displaced by its vast success? Are people better off packing and shipping boxes than selling suits and skirts?

The Internet has roiled industries throughout the economy, and its impact on traditional retail has been seismic. Brick-and-mortar stores have seen their prospects erode precipitously in the past year. Sears, Macy’s, JCPenney — once mighty chains — are on the ropes.

But this revolution may be less about eliminating jobs than redefining them. Michael Mandel, chief economic strategist at the Progressive Policy Institute in Washington D.C., says that e-commerce is creating more jobs than traditional retailers are losing.

When jobs in warehouses, known as fulfillment centers, are counted, e-commerce companies have added more than 400,000 jobs since 2007, while brick-and-mortar retailers lost the equivalent of 140,000 full-time jobs, according to Mandel’s analysis of Bureau of Labor Statistics data. E-commerce warehouse workers also earn 31 percent more on average than their in-store counterparts in the same geographic area, he found. And unlike traditional retail, many of these jobs are full time, with benefits.

“E-commerce is a job creator, not a job destroyer,” said Mandel, who says he’s the first analyst to consider warehouse workers as part of e-commerce. “It’s a win for consumers, who get more convenience. It’s a win for workers with a high school education, who have access to more jobs at higher wages. And it’s a win for retailers that expand into online sales. The only one it’s not a win for is shopping mall owners.”

“A retail apocalypse? Nah. It’s an evolution.”

Staffing specialist Simran Gill talked to applicants at the check-in table during a job fair earlier this month at Amazon’s Fall River warehouse.

Amazon has more than 382,000 full-time employees in the United States, 125,000 of them at its fulfillment centers, and its nationwide job fair Aug. 2 was intended to bring in 50,000 more, the majority of them full time. In Massachusetts, where the company has 3,000 employees and is looking to hire 700 more, job seekers at the warehouse in Fall River waited hours for a chance to tour the facility and apply for a job.

Lenny Betances, 32, a CVS manager in Long Island, showed up in a tie, with his resume. The father of three, who did supply chain work in the Marines and previously worked at a Target distribution center, was hoping his logistics experience could help him land an operations manager role. And what better place to do that than at an Amazon warehouse the size of 20 football fields?

“You just have to keep up with the times,” Betances said. “I shop online for…
