(Radio Iowa) – Union workers at a dozen John Deere plants in Iowa, Illinois and Kansas will vote Sunday on a new, six-year contract. The agreement would cover more than 10-thousand John Deere employees. United Auto Workers leaders have said the deal would provide significant economic gains and it includes a minimum starting wage of 19 dollars an hour that could range as high as 30 dollars an hour if the worker has experience.

John Deere’s Iowa factories are in Ankeny, Davenport, Dubuque, Ottumwa and Waterloo. The last time Deere workers went on strike was in 1986, during the upheaval of the Farm Crisis.
