According to the Washington Post, workers at Amazon's San Bernardino airfreight fulfillment center in Southern California on Monday left their posts in protest for higher pay and benefits. 

"We're not making enough to save anything ... If something goes wrong with my car, I don't have savings. I can't afford to eat healthy food. I have to buy chicken nuggets or noodles," said Sara Fee, a lead organizer of Inland Empire Amazon Workers United, who sorts packages at the air hub. 

Inland Empire Amazon Workers United said 150 workers from the Amazon Prime Air facility in San Bernardino walked out, while Amazon told WaPo (a Jeff Bezos-owned newspaper) it was more like 74 employees. This is the first instance of a coordinated labor action to hit Amazon's air cargo network.

The workers are demanding a $5 per hour increase, health benefits, more safety standards inside the facility, and an end to "retaliation at the warehouse," according to the organization's Twitter account.
