A federal mediator has been called in to work with the NewPage paper mill in Delta County and the United Steel Workers Local 221.
Two years of talks have failed to reach a labor settlement at the Escanaba paper mill where 800 people are employed.
Contract talks were called off earlier this month but started back up today with the presence of a negotiating mediator from Green Bay.
The union requested the mediator and the company agreed to meet in mediation.
The union says job safety and training are the priorities.
NewPage officials say they are hopeful an agreement can be reached.
