McMINNVILLE, Ore. -- Union workers at Cascade Steel Rolling Mills in McMinnville have rejected the latest offer on a proposed three-year contract with Schnitzer Steel Industries.

United Steelworkers Local 8378 represents more than 400 workers at Cascade Steel.

Union President Joe Munger says the vote this week was overwhelmingly against the contract offer.

Union members also reaffirmed their strike authorization for the union negotiating committee, if it comes to a showdown.

Schnitzer officials have requested a meeting with union leaders and a federal mediator next week.
