Boeing says it has withdrawn its pay rise offer to striking workers after negotiations with union representatives reached a stalemate.
The aviation giant accused the union of not giving its proposals serious consideration.
The International Association of Machinists and Aerospace Workers union (IAM) said Boeing was “hell-bent on standing on the non-negotiated offer” which it says was rejected by its members.
Last month, Boeing announced what it called its “best and final” offer to workers, which proposed a 30% rise over four years – lower than the 40% being demanded by the union.
