Let the Code Be Your Guide

The decisions we make every day shape how we show integrity at work and how we earn the trust of our coworkers, customers and communities. When the right path is not immediately clear, our Code of Business Conduct and Integrity Decision Model can help point us in the right direction.

This brief video offers an example of how a routine business situation can raise important ethical questions. It is a reminder that acting with integrity often starts with noticing when something feels off and taking the time to ask for help.

As you watch, consider how these principles apply in your day-to-day work: protecting trust, speaking up when needed and using available resources before a concern becomes a larger issue.

Making the right decision may not always be easy, but our Code points us to resources that can help. If you have a question or believe you have witnessed misconduct, speak up through one of the available reporting paths, including your supervisor or manager, Human Resources, Business Integrity and Compliance, or the  Integrity Helpline.
