(Updates with comment from union in second paragraph.)
Dec. 30 (Bloomberg) -- Rio Tinto Group said workers at its Alma smelter in Quebec rejected the company’s final offer for a new labor accord.
The existing labor contract expires midnight tomorrow, Bryan Tucker, a spokesman for Rio, said today by phone.
A government-appointed mediator has scheduled a meeting with both sides at 3 p.m. today, Marc Maltais, a spokesman for the union, said in a telephone interview.
Rio intends to attend the meeting, Tucker said in an e-mail.
The Alma smelter produces just over 400,000 tons a year of aluminum.
