The coalition of unions — the British-based TU Fund Managers; the Chicago Teachers Pension Fund; and UNISON, which is one of the largest trade unions in Britain and 130 individual shareholders — has sent a resolution to Pearson demanding that it “conduct a thorough business strategy review of Pearson PLC including education commercialization and its support of high stakes testing and low-fee private schools and to report to shareholders within six months.” U.S. and British labor unions whose pension funds own stock in Pearson, the world’s largest education company, are challenging what they say is the firm’s “over-reliance” on educational testing in the United States and plan to take up the issue at an April stockholders meeting.
