Members of New York City’s largest municipal union voted to approve its  contract with the city, officials said.

The Friday vote passed with 97% of all District Council 37 members voting in favor.

The five-year agreement will provide DC37 members with 3% annual raises for the first four years, a 3.25% raise in the fifth year and a one-time bonus of $3,000 immediately to eligible members.

Mayor Eric Adams and the city’s Office of Labor Relations Commissioner Renee Campion hailed DC37 for the ratification.

“This agreement will put thousands of dollars into the pockets of the men and women of DC37, who work tirelessly each and every day to keep our city running,” Adams said in a statement.

The union reached a tentative deal with the Adams administration on the contract last month.

“The overwhelming vote in favor is a testament to this administration’s strong partnership with our labor unions and a reminder that our city is stronger when labor and management work together to uplift our city and its employees,” Campion said in a statement.

The raises included in the agreement are higher than the 1.25% raises the city initially proposed.
