Some Goodyear Tire & Rubber Co. workers said their new contract with the world’s third-largest tiremaker is a bittersweet ending to a 12-week strike.

About 10,000 out of 14,000 striking United Steelworkers members from 12 Goodyear plants in 10 states voted Dec. 28 on the three-year agreement, which includes plans to close a Texas tire factory but creates a $1 billion health care fund for retirees.
