Diversity & Inclusion

diversity and inclusion representation

Diversity & Inclusion

Johns Manville knows that Diversity & Inclusion (D&I) in our workplace are critical for the long-term success of our company. We are committed to retaining, developing and attracting a diverse workforce that fosters an inclusive work environment in which all employees are treated with dignity and respect and can succeed. This is the right thing to do for our employees, our company and our communities.

D&I Council

Johns Manville’s D&I Council is composed of employees from the company’s locations in North America and Europe. The Council meets regularly and works to promote and foster an environment of inclusion. It advocates for inclusivity through content, engagement, discussion, understanding, allyship and training. The Council encourages all employees to take part in celebrating the value of diversity and inclusion.

Celebrating Diversity

A network of employee resource groups (ERGs), born out of Johns Manville’s Diversity and Inclusion Council, is focused on promoting and supporting minority communities in the workplace. This will help build a stronger and more sustainable Johns Manville.

Johns Manville currently has five employee resource groups: WIN@JMJM Wolf PACKembRACEADAPT and JM Pride. 

WIN@JM connects female employees and provides a forum for engagement around topics that uniquely impact women within Johns Manville.

The JM Wolf PACK is focused on developing a support structure by connecting working parents and caregivers together in informal and fun ways; providing educational resources for parents and caregivers to learn, grow, develop and nurture one another and on enhancing career development efforts by leveraging knowledge and experience from current working parents and caregiver leaders.

embRACE promotes education, awareness and understanding of all races and cultures. The group strives to learn about different cultures and human expressions and to defeat group think. embRACE is open to all people who share a passion for uplifting the expressions and traditions from our heritages and beyond, that make humans unique individuals.

ADAPT (Abled and Disabled Allies Partnering Together) supports individuals with disabilities, their caretakers, and family members. ADAPT acknowledges disabilities are strengths, not weaknesses and that individuals with disabilities provide valuable, immeasurable contributions in the workplace. The group provides employee education and facilitates constructive conversation to reduce stigma; build a safe, inclusive and tolerant company culture; and hire and retain diverse top talent at Johns Manville.

JM Pride Logo

JM Pride is a Diversity and Inclusion Employee Resource Group that promotes tolerance and acceptance throughout JM and the communities that we live in, to provide a safe, non-judgmental space as a support network for the LGBTQIA+ community and individuals who share a common vision of social equality.

Community Involvement

JM Gives Back

Johns Manville is a major employer in many of the communities where we operate, and it is our goal to always be an asset in those areas. In addition to great employment opportunities, we support our communities through employee volunteer programs and in-kind donations. 

JM encourages employees, their family members and friends to get involved in projects that make a difference. We provide the tools and resources they need to support the organizations they care about most. With that backing, JM employees don't hesitate to jump in when they're needed. From charity race participation and nature trail maintenance to classroom volunteering and more, we're proud of our employees' willingness to serve.

Between our Denver-area "STARS" program, volunteer projects at our global plant locations and other community investment efforts, JM employees volunteer tens of thousands of hours in their communities every year.
