United Steelworkers inform members of activist investor Ancora Holdings Group's proposal to sell United States Steel Corp.'s modern mills and use the funds to upgrade older union-operated facilities. The union questions Ancora's plans and its opposition to the US Steel-Nippon Steel merger. Ancora, holding 1% of US Steel's shares, aims to change the company's board and appoint a new CEO. Ancora's plan involves selling Big River assets in Arkansas to invest in blast furnaces in Mon Valley, Pennsylvania; Gary, Indiana; and Granite City, Illinois. The activist investor's strategy includes substantial investments in US Steel's legacy assets to boost their productivity. The USW expresses concerns about the potential impact of selling Big River assets on the viability of their facilities. They emphasize the importance of ensuring a strong domestic steel industry for the future. The union acknowledges the threat posed by Big River Steel and its potential impact on national security.
