- The Boeing strike is growing increasingly ill-tempered as both sides have filed NLRB complaints.
- Talks resumed on Monday but collapsed the following day.
- Boeing is losing $50 million a day due to the strike, an analyst estimated.
Boeing filed a complaint on Thursday with the National Labor Relations Board against the union representing 33,000 of its workers.
Seattle-area members of the International Association of Machinists and Aerospace Workers have been on strike for four weeks. They walked out in September after rejecting a new pay deal from Boeing.
Negotiations between Boeing and the IAM fell apart on Tuesday, having restarted the previous day. Both sides have since filed charges with the NLRB, each saying the other is bargaining in bad faith.
Rising tensions are palpable, and a longer strike would continue to hurt Boeing.
Bank of America analyst Ron Epstein estimated that the strike is costing Boeing $50 million a day. The planemaker is also at risk of having its bonds downgraded to junk status by credit rating agencies.
