Responsibility

We have a responsibility to do the right thing – in our business and in the communities where we operate – and to be a responsible corporate citizen.


ONE Focus

We seek to be recognized as a leader in protecting the environment and the safety and health of our employees, contractors, customers and the public.

We vow to continue our commitments to the communities in which we operate and where our employees work and live by investing our time, resources and money.

We promise to act environmentally responsibly to ensure that our actions will benefit future generations.

We pledge to do these things while still providing the quality products and services that our customers have come to associate with the ONEOK name.

We understand that our shareholders expect us to deliver returns on their investments but never at the expense of the safety of our employees or unreasonable impacts on the environment.


Our Values

Ethics: Our actions are founded on trust, honesty and integrity through open communications and adherence to the highest standards of personal, professional and business ethics.

Quality: Our commitment to quality drives us to make continuous improvements in our quest for excellence.

Diversity: We value diversity, as well as the dignity and worth of each employee, and believe that a diverse and inclusive workforce is critical to our continued success.

Value: We are committed to creating value for all stakeholders – employees, customers, investors and our communities – through the optimum development and utilization of our resources.

Service: We provide responsive, flexible service to customers, and commit to preserving the environment, providing a safe work environment and improving the quality of life for employees where they live and work.
