Corporate employees of Amazon were asked on Monday to volunteer their time to the company’s warehouses to assist with grocery delivery as it heads into its annual discount spree known as Prime Day.

In a Slack message reviewed by the Guardian that went to thousands of white-collar workers in the New York City area from engineers to marketers, an Amazon area manager called for corporate “volunteers to help us out with Prime Day to deliver to customers on our biggest days yet”. It is not clear how many took up the offer.
