Immigration Law Giving Unions a Boost Labor leaders increase organizing, see more interest By John Johnson, Newser Staff Posted Apr 30, 2010 9:20 AM CDT 13 comments Comments Day laborers and civil rights advocates gather to make posters for a protest this weekend.

With Hispanic workers worried about discrimination, labor leaders are ramping up organizing efforts and seeing a surge in interest. “They’ve stepped it up big-time,” an immigration and labor attorney tells the Phoenix Business Journal. Unions have long tried to improve their presence in Arizona, especially in industries made up heavily of Hispanics, such as construction and services. This may be their chance. “The more downward pressure you put on workers, the more likely they are to join a union,” says the director of Arizona's AFL-CIO.
