Hundreds of Uber drivers plan to march from San Francisco City Hall to the company’s San Francisco headquarters on May 8, which the drivers believe is the day before the ride-hailing giant will have its initial public offering.

The drivers also plan to strike for 12 hours starting at noon that day, according to Gig Workers Rising, which is organizing the protests in San Francisco and six other cities around the nation, including Los Angeles and Chicago.
