  The initiative will advance opportunity for communities that have historically faced employment discrimination and professional barriers, including: people of color; women; first-generation professionals and immigrants; individuals with disabilities; LGBTQ+ individuals; Americans who live in rural areas; older Americans who face age discrimination when seeking employment; parents and caregivers who face employment barriers; people of faith who require religious accommodations at work; individuals who were formerly incarcerated; and veterans and military spouses.
