Corruption in the Workplace

Engaging in or supporting corruption can damage our company’s reputation, reduce economic viability, and escalate the cost of doing business. The worldwide impact of corruption on business is staggering, with an estimated annual cost in the trillions of dollars. 

MPC maintains an Anticorruption Policy which prohibits employees from offering, promising, authorizing, paying for or providing anything of value directly or through a third party to a customer, potential customer, vendor, business partner, Foreign Government Official, National Oil Company, U.S. Government Official or other third party for the purpose of obtaining or retaining business, gaining influence, or seeking any other improper advantage for the Company.

This video provides an example of just one of the many forms that bribery, a form of corruption, can take.

We’re all responsible for fighting corruption in the workplace. Remember to keep your eyes and ears open and report any questionable practices immediately. Reports may be made to supervisors, managers, Human Resources, Audit Assurance & Advisory Services, HESS&PQ, Law, Business Integrity and Compliance or the Integrity Helpline.
