When Russia invaded Ukraine last February, more than a thousand major corporations pledged to stop doing business in Russia. Most of them kept their word. But according to Yale professor Jeff Sonnenfeld, major corporations like Heineken, Unilever, Philip Morris International and Oreo maker Mondelez haven't kept their word. “These companies are breaking their promises. They are functioning as wartime profiteers,” Sonnenfeld said. “It’s beyond disappointing. It’s shameful and unethical.” Sign the petition urging big corporations to keep their word and immediately stop doing business in Russia.
