Workers at the Illinois Department of Transportation could soon be going on strike. 

The eight local unions that authorized strikes are spread throughout Illinois and represent around 3,800 employees, with 95% voting in favor. They include drivers, highway maintainers and bridge tenders. 

The primary roadblock to getting a new contract is that the state wants to switch workers to a different healthcare plan, something they are opposed to.

The last contract between IDOT and Teamsters expired last July.
