De Blasio reaches labor deal with largest city worker union

Mayor De Blasio struck a tentative deal with the city’s largest municipal-workers union Wednesday, settling on a 10 percent wage hike over seven years.

The agreement with District Council 37 is similar to the contract approved by the teachers union in May.

More than 100,000 workers will tally 1 percent retroactive pay hikes for 2011 through 2013 — the years they worked without a contract.

Their wages will increase the final four years of the contract with a 1.5 percent pay hike in 2014, 2.5 percent in 2015, 3 percent in 2016 and an additional compensation of .52 percent for part of 2017.

The workers will also score a one-time $1,000 ratification payment.

DC 37 represents about 60 percent of the city’s work force, including librarians, janitors, civil engineers, police administration aides and school aides.

The contract will cost $1.75 billion.

But the mayor projects that with the health savings agreed to by the Municipal Labor Committee, the net cost of the contract agreement to the city will be $955 million.

De Blasio has said that he expects all city unions to follow that pattern.
