PITTSBURGH -- The man who guided the nation's largest union federation for 14 years is bidding farewell.
John Sweeney is expected to reflect on his legacy when he delivers the keynote address late Sunday afternoon to hundreds of delegates at the AFL-CIO's convention in Pittsburgh.
Sweeney built the AFL-CIO into a political powerhouse for workers' rights and social change.
But unions also continued to lose members under his watch as millions of U.S. manufacturing jobs disappeared.
Sweeney will be succeeded by longtime deputy Richard Trumka later this week.
Trumka has pledged to make the AFL-CIO even more aggressive politically and to spend more time wooing younger workers.
