A new study shows mixed results in Corporate America’s follow through on diversity and inclusion commitments in the aftermath of George Floyd’s death in 2020 that ignited a global social justice movement.

Nearly three-quarters (74 percent) of Black executives surveyed by CNBC said they’ve seen positive changes in hiring, retention and promotion of Black employees since Floyd’s death.

On the other hand, 43 percent of them said the treatment of Black employees at their company has remained the same, and 9 percent said it has gotten worse. Half of those surveyed said Black employees still have fewer opportunities than other employees at their organization.

In May 2020, a viral video showed former Minneapolis police officer Derek Chauvin kneeling on Floyd’s neck, ignoring the handcuffed Black man saying that he couldn’t breathe – shocking the conscience of the nation. In the so-called racial reckoning that followed, corporations pledged to spend nearly $50 billion toward ending racial inequality and confronting systemic racism according to data analyzed by The Washington Post.

In the survey, companies received high marks for their commitment to diversity, equity and inclusion (DEI) initiatives. The vast majority, 88 percent, of Black executives said they are starting to see results from those commitments at the executive level, and 40 percent said performance on achieving DEI goals are now part of the senior leadership team’s compensation structure.

However, nearly one-quarter (23 percent) of Black executives said they are not equitably compensated compared to their peers. Nearly two-thirds said Black employees were underrepresented in upper management at their organization, and 20 percent said there were no Blacks in leadership. Only 10 percent said Black leadership is higher than it was in 2020.

“The findings of CNBC’s survey suggest that in the post-Floyd era, businesses are demonstrating an increased awareness of the significant opportunity gap faced by Black professionals,” Shundrawn Thomas, founder of investment firm The Copia Group, told CNBC.

“While pockets of improvement are noted, the results reflect the sobering reality that translating pronouncements into progress demands a greater and sustained effort going forward,” added Thomas, who will be a panelist at CNBC’s upcoming Equity & Opportunity forum.
