ALBANY, New York — In a significant setback for Democratic House candidate Brad Lander, the largest municipal workers union in New York City has played a pivotal role in blocking his endorsement by the New York State AFL-CIO. The union's discontent stems from Lander's previous actions as city comptroller, particularly his contentious audit of the city's Health Insurance Stabilization Fund.

Henry Garrido, the union's president, highlighted that the audit, which proposed the dissolution of the fund, was a major irritant. “Our members were really upset about that,” Garrido explained. The rift widened as Lander opposed the union's push to shift retirees to a Medicare Advantage Plan, further straining relations.

Despite these challenges, Lander's campaign spokesperson, Lauren Hitt, emphasized his consistent support for workers' rights. “Brad is a relentless supporter of workers’ rights to organize and bargain collectively,” Hitt stated. She recounted Lander's recent active participation in various labor strikes and his backing of legislative efforts to enhance union powers and address unfair labor practices.

The union's decision also casts a shadow over the potential endorsement of another rising Democratic figure, socialist Darializa Avila Chevalier. While her candidacy has gained attention after defeating Rep. Adriano Espaillat, Garrido admitted to needing more familiarity with her policies. “I don’t know the young lady,” he said, expressing a desire to meet and discuss her platform.

The reluctance to endorse two prominent candidates has caused concern among some labor leaders, who fear a lack of unity could weaken their position in the upcoming November elections. Jen Gaboury, Vice President of PSC-CUNY, emphasized the importance of having a strong, unified New York delegation that champions worker rights.

Garrido refuted claims that his union single-handedly influenced the endorsement decisions, pointing out the complex dynamics within the AFL-CIO, which comprises around 3,000 diverse unions. For a candidate to secure an endorsement, they must garner support from two-thirds of these member unions.

Despite the setback at the AFL-CIO, Lander has garnered endorsements from several other labor organizations, including the United Auto Workers and the Communications Workers of America, indicating a mixed but solid backing in the labor community.

As the political landscape continues to evolve, the influence of union endorsements remains a critical factor in shaping electoral outcomes, especially in strongly Democratic districts like those in New York City. Both Lander and Avila Chevalier represent the progressive wing that has recently disrupted traditional political alignments, signaling a potentially transformative period in New York politics.
