He won with labor support, but something’s going to have to give.

Mayor Zohran Mamdani’s democratic socialism has a union problem. His agenda depends on delivering better City services at lower cost — but the public-sector unions that endorsed him, however reluctantly, have little interest in the efficiency reforms that would make that possible. Before Mamdani can build his urban welfare state, he has to reckon with allies standing in its way.

The vision is ambitious: free buses, universal childcare, City-run groceries — a supposed assault on the cost of living for working-class New Yorkers. But expanding government’s reach requires first proving that the existing government works — and recent events like the Long Island Rail Road strike don’t help the case. Mamdani cannot credibly promise expansive new programs if he cannot fix the ones already in existence.

Recognizing this, Mamdani argued in his inauguration speech that “for too long, we have accepted mediocrity from those who serve the public.” An early executive order calls on each City agency to appoint a “chief savings officer.” During his budget presentation, the mayor highlighted his plans to identify savings by “reducing bureaucratic waste and rendering agencies more efficient and cost-effective.”

Mamdani is right that New York City government can be slow, expensive and resistant to change. The civil service system can take months to grade entry exams — helping explain why the City has more than 14,000 jobs vacant. The Department of Sanitation’s contract with the Teamsters Local 831 has created the norm of two workers per truck, which the Citizens Budget Commission calls the single biggest source of avoidable cost in the department. The union president’s response: “I don’t think there’s ever gonna be a one-man truck in New York City.” Public schools tell a similar story: Per-pupil spending is nearly $42,000 — the highest in the nation and nearly double the California average — yet standardized test results are below the national and State averages, and middling compared to other large cities. Enrollment has fallen by more than 123,000 students since the pandemic and is projected to decline further. Even as students disappear, costs go up.

Despite being nominal allies, Mamdani's and the unions’ goals conflict.

However, reducing what others see as bureaucratic waste threatens public-sector unions and the workers they represent. Efficiency efforts almost always mean doing more with less — automation, consolidation, streamlined processes and elimination of redundant positions. For unions, this is threatening on two levels simultaneously. Fewer positions means fewer dues-paying members and a smaller institutional base, which directly erodes union power. Beyond head count, many of the things that look like inefficiency from a management perspective — restrictive job classifications, limits on task assignments, overtime procedures, seniority-based placements — are hard-won contract provisions that unions and their members regard as fundamental worker protections. Agreeing to streamline them means giving back gains that took decades to secure and opening the door to further erosion in future negotiations.

In short, despite being nominal allies, Mamdani's and the unions’ goals conflict. While Mamdani has occasionally skirted the issue by pointing a finger at failures of contracting services to the private sector, the reality is that, with the exception of shelter, very little of core services — police, fire, education and sanitation — is outsourced. Workers in City hospitals, public parks, environmental protection, housing authorities and libraries are heavily unionized, civil-service-governed workforces, and the unions have successfully resisted privatization of core functions for decades.

Democratic socialism has a ready answer for every fiscal problem: Tax the rich. But even on its own terms, the math doesn’t work. Mamdani’s millionaire’s tax requires Albany’s approval — and Gov. Kathy Hochul has largely said no. And even if she hadn’t, the revenue wouldn’t even fully fund free universal childcare. It would barely cover the budget gaps the City already has.

Therefore, the deal Mamdani is currently offering the City unions is respect, partnership and stability in exchange for patience, flexibility and political alignment — but not much cash. The looming question is whether Mamdani’s idea of collaborative bargaining and finding worker-driven efficiency is possible or if traditional patterns of adversarial bargaining take hold.

State and City budgets will determine how much money the mayor has to play with. While the City is supposed to pass a budget by June 30, the State passed its budget on May 27. One of the most contentious issues was Tier 6 pension reform — public-sector unions’ top priority. The deal lowers the retirement age for teachers from 63 to 58 after 30 years of service and cuts contribution rates for all Tier 6 workers. Statewide cost is $557 million annually — below the unions’ $1.5 billion ask. New York City will absorb a disproportionate share of the costs given its large Tier 6 workforce — a recurring, permanent obligation starting at $128 million in year one — slightly reopening the City’s budget gap. In short, the unions’ victory on pensions may come at the expense of salaries and efficiency reforms.

Indeed, the depth of Mamdani’s fiscal bind is illustrated by his most recent budget maneuver: floating a plan to delay payments into the City’s pension funds, which could save at least $1 billion in the upcoming fiscal year but would push the deadline for meeting long-term pension obligations beyond 2032. A mayor who campaigned on more generous pensions is now proposing to defer paying for that generosity to stay solvent, in effect borrowing from future generations to fund the present.

When the dust from the budget deals has fully settled, the mayor will turn to labor negotiations, with important questions about timing and “pattern bargaining.” Recall that under New York State’s Triborough Amendment to its collective bargaining law, any union contract that “expires” remains in effect until a new one is negotiated. That means public workers continue to receive pay increases as they move up the salary schedule without a new contract, which incentivizes unions to hold out for a deal that is better than the old contract. For instance, rather than negotiate with Mayor Bloomberg during his third term, the unions simply waited to sit down at the bargaining table with his successor. That’s part of the reason why the Police Benevolent Association’s contract, which expired in July 2025, hasn’t been renegotiated.

The other reason is that New York City typically engages in pattern bargaining, whereby one contract with a big union — historically DC 37 or the United Federation of Teachers (UFT) — sets the broad terms of salary raises for other union contracts. However, Mamdani won’t face UFT until late 2027, which leaves DC 37, whose contract expires in November, as the primary candidate to set the pattern. A strategic question for Team Mamdani is whether they set the pattern with DC 37 or wait until the UFT contract expires. 

A mayor who campaigned on more generous pensions is now proposing to defer paying for that generosity to stay solvent, in effect borrowing from future generations to fund the present.

Moving ahead with DC 37 has the advantage of acting while economic conditions are as favorable as they’re likely to get. Waiting until the UFT contract expires in late 2027 raises real risks: a recession, a federal funding cut or some other fiscal shock could arrive in the interim. That concern is sharpened by the fact that Mamdani entered office facing significant budget gaps despite nearly two decades of uninterrupted economic expansion. If the City can’t balance its books in good times, the answer in bad times won’t be pretty. Failing to set the pattern with DC 37 would mean waiting until late 2027 — nearly two years into a four-year term — with virtually every major union contract already lapsed. That’s not a recipe for efficiency reform. It’s a recipe for managed drift.

Mamdani needs a clear-eyed strategy for the unions, not just goodwill. He will face immediate pressure to demonstrate good faith, but with little fiscal headroom to do so. The core problem is that, however aligned the rhetoric may sound, the unions’ fundamental goal is straightforward: higher compensation for their members. For them, the most direct route to “affordability” in the city isn’t free buses or City-run groceries — it’s a bigger paycheck. And if Mamdani can’t deliver on wages, it is difficult to see how he can ask unions to give ground on the work rules and staffing flexibilities that any serious efficiency agenda requires.

It is helpful to recall that the Bloomberg administration had to raise teacher salaries 8% above the civilian union pay pattern to get the UFT to agree to abandon the work rule that required principals to hire the most senior teacher seeking a transfer within the school system irrespective of the principal’s assessment of that teacher’s quality. The reality is that changing work rules that some union members like costs a lot of money. 

If Mamdani’s salary offer is unsatisfactory, the Triborough Amendment lets unions simply wait. They can likely outlast Mamdani, who will face a mounting paradox: a democratic socialist at war with organized labor. Prolonged impasse will be his political problem, not theirs.

For all the fanfare about democratic socialism, Mamdani risks ending up where most of his predecessors did — making modest concessions, deferring hard choices and leaving New Yorkers with the same sluggish, expensive government they’ve always had. Bloomberg moved the needle on education; Giuliani on policing. Everyone else managed the equilibrium. If Mamdani can’t crack the union problem, his democratic socialism won’t fail loudly — it will just quietly echo the status quo.
