Starbucks union threatens to expand campaign as politicians like Zohran Mamdani back striking workers

Unionized Starbucks workers are threatening to expand a US strike against the world’s biggest coffee chain into “the largest and longest” in the company’s history – and urging customers to steer clear.

Starbucks has said the vast majority of its cafes remain open, and expressed disappointment that Starbucks Workers United launched the strike.
