On Christmas Eve of 1968, a guard unlocked a cell door in New York and let out a 40-year-old hospital-workers' organizer named Lillian Roberts, eleven days into a 30-day sentence for leading a strike of New York State mental-hospital employees in defiance of Governor Nelson Rockefeller. Roberts, who rose from that jail cell to become the first Black woman named a New York State Industrial Commissioner and, decades later, executive director of New York City's largest municipal union, died on July 9, 2026, according to a statement from AFSCME, the union she served for most of her working life. She was 98.

She had not set out to be jailed for anyone's cause. Roberts entered the labor movement almost by accident, as a 19-year-old nurse's aide at a University of Chicago Hospital nursery in 1947, where her coworkers made her shop steward and secretary of their AFSCME local before she fully understood what a union was. The work was menial and the pay was low, and within a decade she was organizing Illinois's mental-hospital workers rather than simply representing them.

By the late 1950s, Victor Gotbaum, the AFSCME official who would go on to lead New York's District Council 37, had brought Roberts onto his union staff. When Gotbaum moved to New York to build up the council's ranks among city and hospital workers, she went with him as a director of hospital field operations. Governor Rockefeller's administration was resisting state hospital workers' right to choose their own bargaining representative, so Roberts organized rolling strikes across state mental hospitals, including Creedmoor Psychiatric Center in Queens and facilities in the Bronx and Buffalo, betting that a mobile, unpredictable walkout would wear down an administration that a single strike could not, according to an account maintained by Wayne State University's Reuther Library, which holds archival material on her career.

The tactic violated New York's Taylor Law, which barred public employees from striking, and Roberts drew one of the toughest sentences handed down under that law: 30 days in jail. She served 11 of them before Rockefeller relented and let her go home for Christmas. The strikes worked. AFSCME won the right to represent the hospital workers Roberts had walked out, a victory that helped set the pattern for how New York's public-sector unions organized for the rest of the century.

Roberts carried that organizing instinct into the labor movement's wider reckoning with race. In September 1972, she was among the leaders who gathered at Chicago's LaSalle Hotel as more than 1,200 Black union officials from 37 international and national unions founded the Coalition of Black Trade Unionists, an assembly the organization itself has called the largest single gathering of Black unionists in American labor history. Roberts helped steer the new coalition toward representing the interests of Black workers across every union, not only her own.

In 1981, Roberts left DC 37 to become New York State's Industrial Commissioner, the first Black woman to hold that post, with oversight of the state labor department's enforcement of wage and workplace law. Later in the decade she served as senior vice president of Total Health Systems, a health maintenance organization, before the union that had shaped her career called her back.

In 2002, DC 37 elected Roberts its executive director, the first woman to lead the council in its history. She returned to a union representing New York City's clerical workers, health aides, sanitation staff, librarians, and school aides, and spent the next thirteen years rebuilding its bargaining strength: negotiating a multi-year citywide contract that delivered double-digit wage gains for members and serving as a trustee of the New York City Employees' Retirement System, according to the New York Amsterdam News.

Roberts announced her retirement in October 2014, effective that December 31, recommending her associate director, Henry Garrido, as her successor. "After deep consideration and reflection, I have decided to resign as Executive Director of this great institution effective December 31, 2014," she said in PR Newswire. "It has been a great pleasure to serve the members of DC 37 and to have had the opportunity to lead this Council through some of our most turbulent times in history." She remained a vice president on AFSCME's international executive board after stepping down, closing out a run in organized labor that the union itself measured at 60 years.

DC 37 and AFSCME later endowed a scholarship and a leadership academy in her name, funding tuition for members and their children studying at the City University of New York's School of Labor and Urban Studies.

Word of her death drew tributes from across the labor movement and city government. AFSCME President Lee Saunders said her leadership "left a lasting mark on this union and on generations of labor leaders who followed her." New York City Mayor Zohran Mamdani wrote that Roberts "dedicated her life to working people" and that "from the hospital floor to the front lines of the labor movement with DC 37, she fought for the dignity of public workers with extraordinary courage and demanded that all City workers be treated with respect."

What Roberts built has outlasted her. The scholarship and leadership academy that carry her name still send DC 37 members and their children to class at the City University of New York. The Coalition of Black Trade Unionists she helped found in 1972 still convenes union officials from across the country. And the council she organized as a young field director and rebuilt as its executive director four decades later still represents the hospital aides, clerical workers, and sanitation staff whose right to bargain she spent 11 days in a cell defending in 1968.
