Ethics and Compliance

For more than a century, we have built a reputation as a company with integrity, and we take pride in “doing the right thing.” In accordance with our core value of Ethics, we act with honesty, integrity and adherence to the highest standards of personal and professional conduct.

Code of Business Conduct and Ethics

Our Code of Business Conduct and Ethics is at the core of our culture and our commitment to integrity. Our Code is more than just a set of rules. It’s our guide to doing what’s right and making choices that represent the very best of ONEOK. All ONEOK employees and directors are expected to understand and follow our Code.

Compliance Training

Employee education, training and awareness is an important aspect of our compliance and ethics program. ONEOK corporate compliance training reinforces our commitment to conducting business with integrity, consistent with our values and in full compliance with all laws and regulations. All employees and directors receive annual training on our Code. The training covers various aspects of the Code including conflicts of interest and insider trading and other common scenarios employees may face. Certain employees, based on job roles, receive training on other compliance topics such as antitrust and anti-corruption. Employees also receive regular updates and “micro-trainings” throughout the year on compliance and ethics topics through articles, email, short videos and digital signage.

Business Partners

Our business partners, whether a supplier (goods or services), consultant, vendor, contractor, agent or other third-party provider, act as an extension of our business. For that reason, they share the responsibility to work ethically and continually reflect our Mission, Vision and Core Values. Our Business Partner Code of Conduct (“Business Partner Code”) guides this partnership.


The ONEOK Hotline is administered by an independent third-party. Employees and others can contact the hotline anytime or anywhere via phone (888-393-6135) or the internet at The hotline provides a forum for the submission of complaints or concerns regarding improper or unethical business behavior, questionable accounting, auditing or internal control matters or other matters arising under the Code or Whistleblower Policy. Those using the hotline have the option to report anonymously. The Code and Whistleblower Policy prohibit any form of retaliation against employees for raising a concern honestly and in good faith, or truthfully participating in a company investigation. All reports, including those of retaliation, are investigated.

Corruption and Bribery

ONEOK is committed to conducting business in an ethical manner and in full compliance with applicable U.S. and foreign laws including the U.S. Foreign Corrupt Practices Act, the U.K. Bribery Act and other similar laws governing corruption and bribery. Our Anti-Corruption Policy reinforces that commitment.

Human Rights

Our business has great influence. We also have the responsibility to use that influence for good – to help people thrive. That’s why we do our part to protect basic human rights and preserve the safety and dignity of everyone our business touches. ONEOK is committed to protecting human rights and following the laws regarding things like lawful pay and safe working conditions.

Human exploitation traps millions of people, including children, in horrific situations around the world, including here in the U.S. Individuals who engage in human exploitation use violence, threats, deception, debt bondage and other manipulative tactics for the purpose of exploiting people, sexually and otherwise, for profit. ONEOK is committed to conducting business in an environment free from human exploitation of any kind and has adopted a Human Exploitation Policy to reinforce our commitment.

We expect our employees, suppliers and others with whom we do business, to respect the human rights of all people and engage in ethical labor practices that are free of child labor, forced labor and other forms of exploitation.

Other Policies

Other compliance and ethics related policies include our Antitrust Guidelines and Anti-Harassment and Non-Discrimination Policy.
