Amazon delivery drivers and Starbucks baristas are on strike in a handful of U.S. cities as they seek to exert pressure on the two major companies to recognize them as unionized employees or to meet demands for an inaugural labor contract.

Amazon workers have walked off the job at seven facilities throughout the U.S., including the company's Queens location in New York City, as they push for contract talks with their union.

The Amazon delivery driver strike is nearing its sixth day during the busiest time of the year for last-minute holiday deliveries. The goal is to get Amazon to sit down with the teamsters to negotiate a new contract.
