I say take it to court. Boeing and the rest of the major manufacturers will be worthless if they allow NLRB to get a foothold in this type of decision.
The NLRBs complaint will be heard by an administrative law judge on June 14. Whatever the decision, it is sure to be appealed to the four-member board of the NLRB, which is dominated by radical, pro-union appointees. The worst is Craig Becker, an Obama recess appointee who has argued that the freedom of businesses to invest and make decisions about capital should be limited by the government in order to strengthen unions. If the NLRB finds against Boeing, the company will then appeal the NLRBs illegitimate actions in federal court. Even one of President Obamas liberal, empathetic judges would have a hard time upholding the NLRB, given Supreme Court precedent and the complete lack of a legal basis for these claims.
