"The 99% Spring"
Asian Pacific American Labor Alliance
In Oakland, California, hundreds of workers, youth, and activists rose to their feet to welcome Secretary of Labor Hilda Solis who opened the Asian Pacific American Labor Alliance’s 3-day 11th biennial convention on July 22, 2011. Solis spoke of the employment crisis and the recovery of back wages for victims of wage theft, and was met with a standing ovation for her strong support for the DREAM Act. The convention’s lineup of speakers also included AFL-CIO Secretary-Treasurer Liz Shuler, AFSCME Secretary-Treasurer Lee Saunders, and SEIU President Mary Kay Henry.
In accordance with the theme, "Generations United: Our Jobs, Our Rights, Our Future!" the convention successfully outreached to 200 young leaders. Fiery testimonials were given by student activists and DREAMers Ju Hong and David Cho, as well as Pulitzer-winning journalist Jose Antonio Vargas, who all shared their experience as undocumented immigrants and highlighted immigration as a key issue in the APA labor movement.
APALA honored labor and community leaders during the sold-out gala dinner, and the grand ballroom was at-capacity with over twenty APA elected officials including Congressman Mike Honda, Mayor Jean Quan and State Controller John Chiang joining convention goers for a reception and dinner Saturday evening.
Fred Ross award campaign
In early 2013, mainly Democratic Socialists of America aligned activists, together with many elected officials across the United States came together to urge President Barack Obama to award posthumously the Presidential Medal of Freedom to the legendary organizer, Fred Ross, Sr..
