The offer included raises that were twice the size of those included in the first tentative contract that was rejected by 90 per cent of workers. And it would have kept a pension option for new employees and maintained the workers' no-premium health insurance coverage.
Union locals in Illinois and Iowa were split on the latest offer, with "no" votes in Waterloo, Dubuque, East Moline, and Milan. But "yes" votes in Davenport, Ottumwa, and Des Moines.
Results from Moline were not available.
