Boeing and the Union

From State Line Daily:

The National Labor Relations Board has moved to stop Boeing from building airplanes at a nonunion plant in South Carolina. The Board suggests that a unionized American company cannot, without violating federal labor law, expand its operations into one of the 22 states with right-to-work laws, which protect a worker’s right to join or not join a union.

Here is the question:  Can a company in a right to work state move or open a branch in a state that is a union state?  Is it the existence of a union in that company that makes this a National Labor Relations Board issue?

I believe this decision is dead wrong.  I can’t tell you why I think blocking Boeing is wrong, I just feel it is.  Decisions like this one makes for bad feelings about organized labor.
