Sure. The NLRB can be as precise as it wishes. My point is only that a "union" is not merely what the NLRB deigns to be the state-sanctioned form of worker organizing. There were clearly recognizable unions in the 19th century that were not sanctioned by law. That does not make them any less of a union.
It is only illegal to fire an employ for attempting to form a union of the NLRB sanctioned structure. An organization of workers that undertakes a wildcat strike can be legally fired.
Okay, I see what you mean now. Yeah, the protections are not as encompassing as a non-NLRB-approved use of the word "union" might lead people to believe.
