Kraft Heinz, the maker of Velveeta, Kool-Aid and Grey Poupon, made an offer to buy Unilever for $143 billion in what could be the largest food and beverage deal of all time. Unilever, however, said it isn’t interested in the $50-per-share deal, which represented an 18 percent premium on Thursday’s share price. The British-Dutch company, which has 400 brands including Hellman’s, Ben & Jerry’s and Vaseline, said it “rejected the proposal as it sees no merit, either financial or strategic, for Unilever’s shareholders.” Analysts expect Kraft to sweeten its offer. Toshiba’s chaos deepened, as the Japanese corporate giant’s chairman resigned and the company said it would book a $6.3 billion loss related to its U.S. nuclear business. Analysts are speculating that Toshiba, which employs almost 200,000 people in Japan and has significant investments in the United States, may have to file for bankruptcy. Boeing workers at a plant in South Carolina voted against unionizing, perhaps the most important trial of unions’ influence since President Trump’s election win. After years of bitter campaigning, the International Association of Machinists failed to sway the factory’s 3,000 workers to organize; 74 percent voted against. American Airlines pilot union leaders voted no confidence in chief executive Doug Parker, citing pay and scheduling issues, delays in implementing their full contract and a “toxic” company culture. Pilots and management have been at odds over Parker’s refusal last year to consider a pay raise after aviators at Delta and United airlines increased pay.
