Instacart workers across the country are walking off the job today. They say it’s an emergency protest against unsafe working conditions and low pay during the coronavirus pandemic.

Instacart allows customers to send in orders that workers then pick up at grocery stores and deliver to customers’ homes. Needless to say, it has become very popular in the last few weeks.

In an open letter, Instacart worker-organizers with Gig Workers Collective detailed the danger and humiliation that they face right now thanks to what they say is the company’s negligence, even as “Instacart has turned this pandemic into a PR campaign, portraying itself the hero of families that are sheltered-in-place, isolated, or quarantined.” Instacart, workers say, is not providing adequate protective materials like hand sanitizer or paid sick leave.
