Uber mistakenly sent out an email to some of its drivers and delivery workers last month offering to cover some of their health insurance costs — only to revoke the offer two weeks later. On May 26th, an email from Uber with the enticing subject line “It’s a great time to get health coverage” appeared in the inbox of an unspecified number of the company’s drivers and delivery workers. When they opened the email, they were greeted by an even more alluring proposition: “Uber can help cover your healthcare costs.”
