It can get weirder

Seems some South Carolina Boeing employees have filed a "retaliation" charge against the Machinists' union because they used the NLRB process to bully Boeing into locating the 737 Max production line in Washington State. Through collective bargaining Boeing and the union reached a 4 year agreement which included assurances that the 737 Max line would be built in Washington, and also included a resolution of the 787 Dreamliner case which ensured that contested work relocation would remain in South Carolina. The employees were assisted by the National Right to Work Legal Defense Foundation. I wouldn't bet the farm on a complaint issuing on this charge.
