WASHINGTON (AP) — The U.S. House moved urgently to head off the looming nationwide rail strike on Wednesday, passing a bill that would bind companies and workers to a proposed settlement that was reached in September but rejected by some of the 12 unions involved.

The measure passed by a vote of 290-137 and now heads to the Senate. If approved there, it will be signed by President Joe Biden, who urged the Senate to act swiftly.

“Without the certainty of a final vote to avoid a shutdown this week, railroads will begin to halt the movement of critical materials like chemicals to clean our drinking water as soon as this weekend,” Biden said. “Let me say that again: without action this week, disruptions to our auto supply chains, our ability to move food to tables, and our ability to remove hazardous waste from gasoline refineries will begin.”

Business groups including the U.S. Chamber of Commerce and the American Farm Bureau Federation have warned that halting rail service would cause a devastating $2 billion per day hit to the economy.

The bill would impose a compromise labor agreement brokered by the Biden administration that was ultimately voted down by four of the 12 unions representing roughly 115,000 employees at large freight railroads. The unions have threatened to strike if an agreement can’t be reached before a Dec. 9 deadline.
