Boeing’s largest union rejected a tentative labor contract on Wednesday by a wide margin, extending a damaging strike and adding to the mounting financial problems facing the company, which hours earlier had reported a $6.

Before it can get on the long path to recovery, the aerospace giant needs to get workers back in its factories.

The strike by 33,000 workers at Boeing will continue after rank-and-file union members rejected an offer from the company and decided to remain on the picket lines instead.
