The Starbucks Workers United escalated its “Red Cup Rebellion” strike over unfair labor practices on Black Friday, announcing that 120 stores in 85 cities had joined the effort, while Starbucks claims fewer than half that number were impacted and that the strike has caused minimal disruption over the last three weeks.

Since calling the strike on November 13, the company’s highly trafficked “Red Cup Day” when it gives away free reusable coffee cups to customers, Starbucks Workers United reports new stores have been added to its strike list each passing week, now totaling 120 stores.

SWU claims that baristas in 550 unionized stores are prepared to continue escalating the strike until Starbucks delivers a fair union contract and resolves hundreds of unfair labor practices charges.
