Procurement Department Personnel

Maintaining the highest standards of integrity in our procurement processes,
and in bidding or negotiating contracts, is essential to performing on current and
future contacts, products and services. Special guidelines for acceptable practices
with suppliers, as revised from time to time, must be followed by procurement
personnel due to the special positions they have with regard to suppliers. For
more information about this topic, see Procurement Department Guidance for
Acceptable Practices with Suppliers.

Human Resources

We will comply with the letter and spirit of applicable laws concerning
equal employment opportunities and will maintain a work environment free from
discrimination based upon race, color, ethnicity, religion, national origin, sex, age,
disability, sexual orientation, gender identity, veteran status, marital status, genetic
information, or any unlawful factor. Certain states and cities have additional
categories protected from discrimination, and we comply with those rules.
Our diverse, engaged and dedicated workforce is our greatest asset, and the
continued well-being of our employees is critically important for our success.
Engagement happens when we bring together exceptional and diverse talent
with different backgrounds, genders, ethnicities, qualifications, perspectives,
experiences, voices and skills to ensure that we will consistently develop the
best ideas and advance our world-class ambition. Enabled by an inclusive
environment where each person feels like they belong, are valued and can speak
up, engagement allows us to forge stronger, more productive connections. We
are committed to providing all employees with the programs, resources, support
and opportunities necessary to grow. We strive to create safe, healthy, diverse and
highly engaging workplaces and hope that our decisions in this area will extend far
beyond our business, positively affecting people and communities for generations
to come. This means embracing our uniqueness by treating everyone with dignity
and respect, looking out for each other, speaking up, showing up and always
doing what is right. Our strength is derived from our people, and championing this
strength empowers each of us to make a difference in our pursuit of excellence.
