Gov. Andrew Cuomo in a statement on Wednesday said a strike on the Long Island Rail Road is “just not an option” and added the “false belief” Congress would become involved was an impediment to any resolution.

“A strike is just not an option and would be a terrible failure by both the unions and the MTA,” Cuomo said in a statement this afternoon.

The statement from the governor’s office also said the state’s elected representatives in Washington had indicated Congress won’t become involved in the dispute — a move the governor said was an incorrect assumption made by the union representing LIRR workers.

“I want to thank the New York State Congressional Delegation for making it abundantly clear today that Congress will not act to bring about a labor settlement at the Long Island Rail Road,” Cuomo said. “The unions’ false belief that Congress would step in to mandate a settlement was a major impediment to any real progress. With this obstacle removed, it is now clear that the only path to resolution is at the bargaining table between the MTA and the unions, and they should proceed in good faith.”

Cuomo on Monday was under the impression that Congress would have to become involved in the dispute in order to save off a strike because of federal law.

“I’ve gotten involved in a number of union disputes, but those are contracts with the state of New York and they are in the contracts with the state of New York,” Cuomo told reporters in New York City on Monday. “The LIRR is a little different, because the way law is written, it’s actually Congress that can end the strike and impose a settlement one way or the other. So right now it seems that Congress is pivotal to what happens, and from what I read in the newspapers, it’s going to depend on what Congress intends to do and what they say they’re going to do.”

Earlier in the day, Cuomo’s GOP opponent, Rob Astorino, said in a video statement the governor should involve himself in the dispute and help avert a labor action.
