Nearly a month into a union walkout, the aerospace giant withdrew its latest contract offer, and the two sides exchanged blame over the breakdown.

Boeing has withdrawn a contract offer that would have given striking workers 30% raises over four years after talks broke down.

Over 30,000 Boeing workers plan to strike after rejecting a new labor contract. The strike would halt most of Boeing's production in Washington and Oregon. The rejected contract included a 25% wage increase and a new plane program in Seattle.
