Boeing and the union that represents 33,000 striking employees at the company say talks between the two have broken down and no new talks are scheduled.

Boeing on Tuesday said that it has withdrawn its pay offer after negotiations with the International Association of Machinists and Aerospace Workers (IAM), whose members are on a strike against the company.

Boeing withdrew a contract offer for 33,000 machinists who have been on strike since mid-September, and said further negotiations “do not make sense at this point.”
