An inclusive environment for all
We are committed to creating an inclusive environment where employees feel comfortable being themselves. We also want everyone to feel that their voices matter, that all cultures are respected, and that perspectives, as diverse as they are, are not only welcome, but essential to our success. We treat each other fairly and with dignity, regardless of race, gender, nationality, ethnicity, religion, age, sexual orientation or any other distinguishing aspect.
At Rio Tinto, we welcome and encourage applications from women, older workers, persons with disabilities and representatives from diverse backgrounds.
Everyone is different, and we believe that these differences are our strength. The diversity of skills, life experiences, and perspectives within our team enhances the way we work and our ability to succeed together.
