School safety agents are calling on the de Blasio administration to resolve their gender-based wage discrimination lawsuit.
The union representing the agents, about 70 percent of whom are women, first filed the lawsuit against the city back in 2010.
They say it's unfair that school safety agents make $7,000 a year less than other kinds of city security guards, who they say are mostly men.
Mayor Bill de Blasio has said he wants to settle the suit, which protesters say is the largest of its kind in the country.
"Put an end to the ongoing unfairness that these dedicated public servants have endured for far too long," said City Council Speaker Melissa Mark-Viverito. "It's encouraging to hear that the mayor wants to settle, but we want to move it ahead much more quickly."
"It's representative of what thousands upon thousands of women experience on a daily basis," said Sonia Ossorio of the National Organization for Women.
Protestors were joined at City Hall by Lilly Ledbetter, whose Supreme Court case against Goodyear led to the creation of the federal fair pay law that bears her name.
