MASSENA -- Contract negotiations between United Steelworkers and Arconic are “stalled,” according to a statement from the union.

USW members at Arconic will continue to work under their existing contract while negotiations continue, USW said.

The union’s news release said Arconic management is “demanding economic and non-economic concessions that the union has dismissed as excessive.”

“USW International Vice President Tom Conway, who chairs the negotiations, said that the proposals currently on the table from Arconic contain concessions both too broad and too deep for USW members and their families to absorb,” the union said. “Representatives of the USW negotiating committee will return to their local unions in the coming days to provide detailed updates from the table and discuss the union's next steps.”

“Arconic should understand by now that we are determined to negotiate fair agreements and nothing less,” Conway said in a prepared statement. “Our members throughout the aluminum industry—especially at these facilities—create tremendous value and have earned and deserve a contract that recognizes that their contributions to the company's success.”
