Caterpillar and the International Association of Machinists union reached a tentative six-year contract deal Wednesday that would end a 15-week worker's strike at Caterpillar's Joliet plant. But Machinists Local Lodge 851, which represents striking workers, looks poised to reject the agreement.

The New York Times reports that Tim O'Brien, president of the union local, will recommend members vote against the plan. And the Chicago Sun-Times interviewed striking workers who disparaged the agreement, pointing out that it keeps wages frozen for the majority of workers even as the company enjoys record profits.

Union members are scheduled to vote on the new contract tomorrow.
