About 100,000 municipal workers represented by District Council 37, the city's largest umbrella labor union, would get 10 percent in raises over seven years under a tentative contract agreement struck with City Hall.
If the rank-and-file DC 37 members ratify the deal, they will also get a $1,000 signing bonus.
With the latest agreement, Mayor Bill de Blasio has settled expired labor pacts with almost 60 percent of the city's 350,000-member workforce, which includes city-run public corporations.
"It is long overdue," de Blasio said Wednesday of the settlement at a City Hall news conference. He was alluding to the 152 bargaining units whose contracts long ago expired under his predecessor, Michael Bloomberg. De Blasio has whittled that number down to 92.
DC 37's contract expired in 2010. Its members include some 1,000 job titles -- engineers, project managers, architects, librarians, museum staff, parks employees, clerks, office personnel and child-welfare specialists.
De Blasio cut a $9 billion deal in May with the 110,000 teachers and other school personnel represented by the United Federation of Teachers.
The DC 37 settlement, worth about $1.75 billion, follows the pattern set by the UFT contract. Both contracts' costs will be offset by billions in promised health care savings, the administration says.
The two contract price tags vary drastically because the teachers went without raises for about two years longer than DC 37.
DC 37 workers will get retroactive raises to 2011, 1 percent each September going to 2013, 1.5 percent in 2014, 2.5 percent in 2015 and 3 percent in 2016. The contract also provides a 0.52 percent raise on March 3, 2017. The contract expires that July. How and when the back pay will be doled out has yet to be determined, officials said.
The agreement also calls for joint committees to diversify the workforce and its management, as well as identify and eliminate waste.
Still outstanding are contracts for several high-profile unions, including those representing uniformed personnel such as police officers, firefighters and jail guards. Their leaderships have rejected the pattern set by the UFT on the grounds that their jobs are more dangerous than the rest of the workforce's and should command bigger raises.
De Blasio stood firm Wednesday: "I respect them and I respect their work intensely," but added that pattern bargaining has a "long and clear history in New York City. He added: "We expect this pattern to hold throughout the process."
