Rio Tinto Kennecott reaches labor contract agreement with four unions

South Jordan, Utah (April 4, 2017) – Rio Tinto Kennecott has reached a labor contract agreement with the four unions that have been in collective bargaining since late February.

Of Kennecott’s approximately 1,600 employees, more than 1,200 are represented by one of the four unions, including the United Steelworkers, International Union of Operating Engineers, International Association of Machinists and International Brotherhood of Electrical Workers.

“We have had a strong long-term relationship with our unions, and the news of ratification and successful terms represent that relationship,” said Marc Cameron, managing director, Rio Tinto Kennecott. “This agreement allows our employees and our organization to focus on safety, efficiency and our customers.”

“This is a good example of improved working relationships with the unions that represent our employees and our continued focus on making our operations sustainable,” said Rick Willmott, head of employee relations, Rio Tinto. “I specifically want to mention the District and International Leadership of the United Steelworkers, including Leo Gerard, for their efforts to progress the overall relationship.”

“I want to thank both parties for a job well done in finding joint resolution to the issues that we have faced for many years and how we will both move successfully forward in the future,” said Leo Gerard, president, United Steel Workers International.

Kennecott was informed by union leadership on April 3, 2017 that their members had ratified the proposal provided by Kennecott. These are the highlights of the new agreement:

  • Five-year agreement
  • Continued quality healthcare and retirement benefits
  • Competitive wage increases every year


The contract will take effect April 4, 2017. The agreement allows Kennecott to have predictable labor costs, which helps the business plan for future operating and capital investments.
