Walkout at Amazon Air Hub in San Bernardino

Dozens of Amazon employees at the company’s air hub in San Bernardino, Calif., on Monday abandoned their workstations mid-shift over low wages and concerns regarding heat safety.

The walkout in Southern California marks the first coordinated labor action in Amazon’s growing airfreight division, which uses Prime-branded planes to fly packages and goods around the country much like UPS or FedEx. The employees, who are independently organized, said they didn’t plan to return to work on Monday, in an effort to pressure Amazon to raise wages and improve safety.
