Thousands of New York City residential building workers are preparing to vote on whether to authorize a strike, setting up a potential labor action that could affect hundreds of thousands of apartment dwellers across the five boroughs.

Members of 32BJ SEIU, the union representing more than 34,000 doorpersons, superintendents, porters, handypersons and resident managers, will gather on Park Avenue on April 15 to take a formal strike authorization vote. The vote comes five days before their current contract with the Realty Advisory Board on Labor Relations expires on April 20.

The move follows what the union described as “dramatic and insulting changes” proposed by RAB, the organization that represents the city’s residential real estate industry at the bargaining table. According to 32BJ SEIU, those proposals would shift healthcare costs onto workers through premium sharing, create a lower-paid “Tier II” workforce, expand the use of temporary workers, weaken contract enforcement procedures and leave pension improvements off the table entirely.

Manny Pastreich, the union’s president, said the proposals cross a fundamental line. “We won’t let the thriving real estate industry raise health care costs, jeopardize retirement security, and undermine the core fabric of a labor contract that thousands of working families depend on,” Pastreich said in a statement.

More than 2,000 union members met last week to set the April 15 date, and over 1,400 strike captains are already mobilizing across the city to prepare for a potential work stoppage. The union says its members serve roughly 600,000 New York City households across 3,500 co-ops, condos and apartment buildings. That number makes clear how quickly a strike could ripple through the daily routines of residents in buildings across Manhattan, Brooklyn and beyond.

RAB President Howard Rothschild said the realty group respects the union’s right to authorize a strike and that all member buildings are preparing for that possibility. He said negotiations will continue over the next month with the goal of reaching a fair contract. But Rothschild also pointed to what he called real pressures facing the industry, including the potential for a rent freeze affecting roughly one million rent-stabilized apartments if Mayor Zohran Mamdani follows through on his campaign pledge to implement a 0% rent increase policy.

That context matters. Landlords of rent-stabilized buildings operate under tight margins, and a mandated freeze would constrain revenue at the same moment they face demands for higher labor costs and maintained benefit packages. Whether that argument lands with negotiators or the public is another question.

For workers, the stakes are concrete. Healthcare cost-sharing proposals could mean hundreds or thousands of dollars per year out of pocket for workers who already earn wages calibrated to New York’s punishing cost of living. A Tier II structure, if adopted, could erode pay standards for new hires over time, splitting the workforce and weakening collective bargaining power in future contract cycles.

Brighton Beach, Flatbush, Jackson Heights. A lot of these workers live in the same neighborhoods they serve, paying the same rents, riding the same subway lines. They are not abstract labor figures in a contract dispute. They are the people who keep city buildings running, and their pay and benefits directly affect whether working-class New Yorkers can hold onto a foothold in a city that keeps getting harder to afford.

The four-year industry-wide agreement that expires April 20 covers a workforce that touches virtually every corner of the city’s residential real estate sector. With negotiations apparently stuck after last week’s proposals, both sides have roughly three weeks to find a resolution before the contract deadline arrives.

If no deal is reached and workers vote yes on April 15, a strike could begin as soon as April 21. That would leave building owners scrambling and residents of affected buildings without the staff they rely on for basic services. City officials, who have so far stayed quiet, may find themselves pulled into the middle of talks quickly if the situation escalates.

The April 15 rally and vote on Park Avenue will be the clearest signal yet of how ready union members are to walk.
