Unionized Starbucks workers are electing strike captains and getting customers to pledge they won't cross picket lines. They’re amassing in front of stores with picket signs, borrowing a slogan that UPS Teamsters used during their 2023 contract campaign: “Just Practicing for a Just Contract.” Thirty-eight stores held practice pickets in early October, and starting October 25, 80 more stores plan to hold pickets and sign up customers to a “No Contract, No Coffee” pledge, promising not to patronize any Starbucks in case of a strike.
