Pittsburgh, Sept. 13 (UPI) -- U.S. President Barack Obama's speech Tuesday at the AFL-CIO convention comes amid a revival of labor optimism and spirit of empowerment, union officials say.
A grass-roots push of AFL-CIO members representing every congressional district during Obama's 2008 presidential campaign helped him win the election, the Pittsburgh Post-Gazette reported.
"We recognize that working people are at the edge of a huge wave of change," said John J. Sweeney, AFL-CIO president. "We're ready to mobilize as never before to create an economy that works for everybody.
The convention will bring together 1,000 union delegates, 2,000 guests and 250 visitors from unions throughout the world.
