The labor group UNITE HERE broke away from the Change to Win group of unions, and re-affiliated Thursday with the AFL-CIO.
UNITE HERE, which represents some 265,000 workers, announced it would leave the Change to Win coalition it joined in 2005 as part of an effort to push for reforms in the AFL-CIO.
"I can’t think of a more uplifting way to begin this day than by welcoming UNITE HERE back to our union family as an affiliate of the AFL-CIO," newly elected AFL-CIO President Richard Trumka said in a statement. "A united labor movement will serve the interests of working people during this time of incredible opportunity and progress."
UNITE HERE had discussed rejoining the AFL-CIO earlier this year, along with several other unions that had splintered off earlier this decade.
The re-affiliation comes after Trumka was elected the new president of the AFL-CIO at the group's annual convention this week in Pittsburgh.
"In UNITE HERE, we know what a fighter for workers Rich Trumka is, and we pledge to stand with him and fight with him to get workers what they deserve: a piece of the American dream. Solidarity will always overcome division," UNITE HERE President John Wilhelm said. "Our union will continue to be a strong and growing member in the house of labor."
Trumka emphasized that he will continue to reach out to other organized labor groups to pursue re-affiliation with the AFL-CIO.
