On Friday, front-line workers from Amazon, Instacart, Shipt, Target, and Whole Foods have organized to walk out of their jobs together over demands that their companies provide better pay, benefits, and protections…Despite being classified as essential workers in a crisis, they say, their companies treat them as disposable…That workers are now looking outside their own company isn’t surprising, some experts say. “The problem isn’t unique to Instacart, or Target, or Whole Foods. The problem is across essential work,” says Benjamin Sachs, a labor law expert at Harvard Law School…In other countries, there’s ample precedent for industrywide organizing among workers with similar jobs, like a delivery workers union, but not in the United States. “In fact, under existing law, it’s almost impossible to form unions and bargain at the level of the sector,” says Sachs. As a leader on Clean Slate for Worker Power, a project at Harvard Law School, he recently called for a change in labor law that would allow people who do similar types of work to band together and demand industrywide changes, either as a union or an official collective of workers. “You don’t fix cross-sectoral health and safety problems with just a group of workers at Whole Foods,” he says. Friday’s strike, Sachs says, highlights the pressing need for that kind of change. So far, companies like Amazon have successfully fought off efforts to form unions within their workforce. Withholding labor is only one part of a strike’s goals. The other part is rallying consumer action. “Even a small strike with a lot of attention can hugely influence consumers—and these are all entirely consumer-dependent companies,” says Sachs.
