ThIs chapter examines the early Sweeney years, a remarkable time full of optimism for the AFL-CIO, and for many of America’s working people. Sweeney launched a wide range of reforms, putting an increased emphasis on organizing, political mobilization, and grassroots work, and forging new bonds with unions in other countries. He also introduced unprecedented diversity into the AFL-CIO, appointing more female staffers than ever before, and reaching out to female and minority workers. Sweeney’s efforts secured results; in 1998, for example, union membership increased by 101,000 over the previous year, a notable turnaround. The optimism was still evident at the end of 1999, when the AFL-CIO joined with environmentalists and engaged in mass demonstrations at the World Trade Organization meeting in Seattle. Two events – the contested 2000 presidential election and 9/11 – acted as turning points, initiating a domestic climate that was much more hostile to the AFL-CIO.
