The union representing Boeing factory workers who are currently on strike in the Pacific Northwest says contract talks “broke off” with the company after another bargaining session

Boeing said on Tuesday it has offered to extend the timeline for a vote on a new contract by the union representing thousands of its striking U.S. West Coast workers, after they rejected the company's initial Friday deadline.

Boeing has withdrawn a contract offer that would have given striking workers 30% raises over four years after talks broke down.
