I’m not so sure. The NLRB was pressured by the union to prevent Boeing from opening the SC plant. Boeing gets to proceed because of offerings of red cloth and sparkly things.
IMO it seems that this was a slight of hand maneuver to save face for thug... err I mean union leaders.
Once the plant is up and running in SC, screw the machinist union.
I defer to the folks who’ve been following this more closely than I.
“red cloth and shiny things”
