"This is one of the worst examples of unelected bureaucrats doing the bidding of special interest groups that I've ever seen," U.S. Sen. Lindsey Graham, a Republican, said in a statement. "In this case, the NLRB is doing the bidding of the unions at great cost to South Carolina and our nation's economy."
Republican Gov. Nikki Haley, who is being sued separately by the IAMAW for vowing to keep unions out of the Boeing plant, called the labor organization "meddlesome" and "self-serving."
"This bullying will not be tolerated in South Carolina," Haley said in prepared remarks.
The IAMAW said that before Boeing announced its North Charleston plant, it offered the company an "unprecedented 11-year agreement" that would have given the company the "labor peace" it claimed it needed.
Since then, it said, Boeing "hasn't been willing to have any serious conversations about its future in Puget Sound."
"I'm ready to have that conversation," said Tom Wroblewski, president of union's District Lodge 751 in Seattle. "We need to sit down and talk about our shared future, and what both sides need to be successful long-term. That kind of conversation is what's in the best interest of our company, our members and our communities."
