Starbucks Corp. said it reached out to the union representing hundreds of its stores to try to end an impasse over contract talks, a conflict that has frayed the coffee giant’s relationship with some of its frontline employees.

The chain is looking for talks to resume with a “set of representative stores in January” and is setting a goal of completing “bargaining and the ratification of contracts in 2024,” Starbucks Chief Partner Officer Sara Kelly said in a letter dated Dec. 8 addressed to Workers United President Lynne Fox. The company said it’s open to “ideas and rules of engagement on how bargaining could proceed.”
