New York City Mayor-elect Zohran Mamdani announced the appointment of Julie Su as the city's inaugural deputy mayor for economic justice. Mamdani, a member of the Democratic Party, highlighted Su's previous role as acting US Labor Secretary, where she was instrumental in advocating for workers' rights, including fair wages and pension protections for union members.

During a press conference in Staten Island, Su emphasized the importance of dignity in the workplace, stating that in a city with significant wealth, no individual should be regarded as disposable. She articulated that justice should manifest in tangible benefits such as livable wages and supportive work environments.

Su's background includes serving as California's labor secretary and deputy US labor secretary. Her nomination to lead the Department of Labor was blocked by some Republican senators and certain Democrats, leading to her appointment in an acting capacity from March 2023 until January 2025. Throughout her tenure, she focused on issues affecting gig workers, pension preservation, and workplace safety, particularly in response to the COVID-19 pandemic.

Mamdani's administration aims to fulfill campaign promises that include free public childcare, municipal transportation, rent stabilization, and the establishment of city-owned grocery stores. Advocates for labor rights have expressed optimism regarding Su's appointment, viewing it as a significant step towards prioritizing the needs of working-class citizens in city governance. The NYC Central Labor Council and other labor organizations have praised Su's extensive experience in labor law enforcement and her commitment to fighting for working families.
