Investors who proclaim their attachment to ESG should address longstanding worker concerns first, says bottling plant worker Cesar Moreira. : This Labor Day, KKR has an opportunity to improve working conditions and honor the rights of Refresco employees by remedying unsafe working conditions and supporting a fair contract that prioritizes worker health and safety. Earlier this year, private equity firm KKR acquired a majority stake in Refresco, the world’s largest independent bottling company. Refresco produces beverages such as BodyArmor Sports Drink for Coca-Cola, Gatorade for Pepsi, Arizona Iced Tea, and Tropicana juices.
