Zohran Mamdani promised New York's teachers union everything they wanted – then sued them seven months later.
Now the United Federation of Teachers is fighting their own mayor in court over a $10,000 raise for school aides making around $33,000 a year.
What he just did to the people who put him in office is something even his own allies didn't see coming.
Zohran Mamdani's Promise to the UFT That Won Him Their Endorsement
The UFT – New York City's largest teachers union with nearly 200,000 members – endorsed Mamdani during his 2025 mayoral campaign.
That endorsement didn't come for free.
During the campaign, Mamdani appeared publicly with UFT leadership and personally committed his support to a bill giving school paraprofessionals a pay raise.
These are the aides who work directly with the city's highest-need students – kids with disabilities, behavioral challenges, and severe learning difficulties.
Entry-level paraprofessionals in New York City public schools earn around $33,000 a year.
That's not a living wage in New York City.
That's barely a rounding error on what it costs to rent an apartment in Brooklyn.
Lifting paraprofessional pay was the UFT's top priority.
The union delivered its endorsement.
Mamdani won City Hall.
What a Socialist Does When the Bill Comes Due
The New York City Council passed the RESPECT Check Act unanimously – 49 to 0 – on July 16.
The law offered up to a $10,000 bonus for school paraprofessionals.
Mamdani didn't veto it.
He didn't sign it either.
He let the clock run out, allowing it to become law automatically under city charter.
Then, on August 19, his administration filed a lawsuit to kill it.
The argument? The law violates New York's Taylor Law – the decades-old statute that controls how public employee pay gets negotiated.
Here's the translation for anyone outside a law school: Mamdani is claiming the city council doesn't have the authority to give paraprofessionals a bonus because that kind of compensation has to go through union contract negotiations.
It's a legal argument with some merit – which makes it more infuriating, not less.
Mamdani had months to fix this through negotiations.
Instead, he sued.
UFT Files Motion Against Mamdani Lawsuit Over Teacher Pay
The UFT filed a motion to intervene on August 25 – putting the union in direct legal opposition to the man it endorsed for mayor.
UFT President Michael Mulgrew didn't mince words.
"The City Council would not have introduced – let alone passed – this bill if it were illegal," Mulgrew said.
He added: "This administration must keep its promises, and we won't stop until it does."
City Council Speaker Julie Menin was equally direct.
"Every member of the Council, in a unanimous and bipartisan vote, supported the RESPECT Check Act because it is unacceptable that paraprofessionals who support some of our highest-need students are earning as little as $32,000 a year."
And yet Mamdani sued anyway.
He said publicly last week that his talks with the UFT have been "productive" – which is the political word for "I'm stalling."
NYC Mayor Mamdani Has Now Broken Promises to Two Unions
The UFT isn't Mamdani's first union betrayal in seven months.
New York City's building trades have been sounding the same alarm since June.
Brian Hunt, president of Steamfitters Local 638, told Fox News that Mamdani "mentioned union labor, union labor, union labor quite a few times throughout his campaign" – and has yet to show up with actual union contracts for his affordable housing agenda.
This is the pattern with socialist politicians.
They talk about workers constantly.
They pose with union bosses for endorsement photos.
They quote Eugene Debs in their victory speeches.
Then they get into office and discover that governing costs money – and the people who actually pay for it aren't the workers they campaigned with, they're the city's budget sheet.
Mamdani froze rent – one of his "super socialist" core promises, as one union boss put it – because that's political performance.
Freezing rent doesn't cost City Hall anything directly.
Giving 26,000 school aides a one-time $10,000 payment costs the city roughly $244 million.
And now you're watching what happens when the bill arrives.
When the Socialist Mayor Loses His Own Coalition
This isn't a story about the UFT getting a raw deal.
This is a story about a socialist getting exposed by his own people.
The steamfitters are warning others not to make the same mistake his campaign made to them.
Mamdani's whole political identity is built on one promise: that he's different from the politicians who sold out the working class.
Seven months into the job, his own coalition is in court proving he isn't.
The Left spent years telling workers that socialists were the answer.
New York City is the answer.
