Everyday Respect

Transparency is key to making meaningful, lasting changes that create a safe and respectful workplace. That’s why, in March 2021, Rio Tinto commissioned an expert-led independent review of our culture to better understand, prevent, and respond to harmful behaviors.

At U.S. Borax, we are taking specific actions directly linked to the 26 recommendations proposed in the Everyday Respect report, which include: Contractor listening sessions, an early career network, and leadership and employee-wide training.
