New York CNN Business  — 

Corporate America has said very little following this week’s Texas school shooting that left 21 people dead. Yale professor Jeff Sonnenfeld is calling out their silence.

Sonnenfeld, a vocal advocate of corporate social responsibility, applauded Goldman Sachs CEO David Solomon for speaking up but said more is needed.

“This voice is a start but still not the loud chorus of CEOs and other leaders needed,” the Yale professor told CNN in an email on Friday.

Jeffrey A. Sonnenfeld, Senior Associate Dean for Leadership Studies & Lester Crown Professor in the Practice of Management at Yale University.

Sonnenfeld, whose list of companies cutting ties with Russia pressured other brands to do the same, noted that many leaders have shied away from making statements following Tuesday’s shooting at Robb Elementary School in Uvalde, Texas.

“As before, where are the united clergy, the trade union leaders, the pension funds, the institutional investors, the professional associations and the campuses (who did speak out so well post-Parkland)?” Sonnenfeld said, referring to the 2018 shooting at Marjory Stoneman Douglas High School in Parkland, Florida.

Neither the US Chamber of Commerce nor the Business Roundtable, the two leading business trade groups, have issued statements since Tuesday’s shooting.

Playing with fire

Corporate America has faced growing pressure from their employees and shareholders to act socially responsible. Many companies have recently taken stands on hot-button concerns, including abortion rights, unconscious bias in the workplace, gender equality, LGBT+ issues, voting rights and the preservation of democracy.

The Business Roundtable in 2019 said corporations are no longer beholden exclusively to shareholders, and companies have a responsibility to improve society by serving all stakeholders – including customers and employees – ethically, morally and fairly.

Yet, recently, some Republican politicians have taken action against companies that have spoken out about controversial new laws.

Georgia’s Republican-controlled House in April 2021 voted to revoke a major tax break for Delta Air Lines (DAL) as punishment for its CEO’s public criticism of the state’s controversial law that restricts ballot access. Lawmakers ultimately let Delta keep its tax break. But Georgia Republicans rescinded a similar tax break in 2018 after Delta cut ties with the National Rifle Association.

This year, Florida eliminated a tax break for Disney after CEO Bob Chapek, under pressure from employees, denounced the state’s so-called Don’t Say Gay law.

It’s not clear if companies’ lack of action on the latest mass shooting is a result of complacency, fear or some other reason. But Sonnenfeld says the silence is deafening.
