You're likely here because you’re stuck in an automated loop. Maybe you're a nurse trying to verify your employment for a mortgage, or a fresh graduate wondering why your application for a clinical coordinator role has been "under review" for three weeks. Honestly, the Mount Sinai Hospital HR department is a massive machine. It has to be. When you’re dealing with one of the largest health systems in New York City—we’re talking over 42,000 employees—the human resources function isn't just one office with a water cooler. It’s a sprawling network of recruiters, benefits specialists, and labor relations experts spread across Manhattan, Queens, Brooklyn, and Long Island.
It's frustrating. I know.
Getting a straight answer from a "Human" Resources department shouldn't feel like solving a Rubik's Cube in the dark. But at Mount Sinai, the "Health System" umbrella covers everything from the Icahn School of Medicine to Mount Sinai Morningside. Each wing has its own quirks. If you're looking for the central hub, you're usually looking at the 150 East 42nd Street location in Manhattan, though much of the "front-facing" HR work has moved to digital portals and decentralized office clusters near the individual hospital campuses.
The Reality of the Mount Sinai Careers Portal
Most people start at the Sinai Careers portal. It’s the gatekeeper. If you're applying for a job, you aren't emailing a person; you're feeding an Applicant Tracking System (ATS). This is where most resumes go to die if they aren't formatted correctly. You’ve got to use the right keywords—not because it's "gaming the system," but because the recruiters at Mount Sinai are often managing hundreds of open requisitions at once. They use filters. If the job description asks for "Epic EMR experience" and you just wrote "computer skills," the HR software might never show your face to a human being.
Recruitment at Sinai is specialized. There isn't just one "recruiter." There are nursing recruiters, allied health recruiters, and non-clinical corporate recruiters. They operate in silos. If you're trying to follow up on an application, calling the general Mount Sinai main line is a waste of your afternoon. You'll get transferred four times and end up back at a dial tone.
Instead, look for the specific talent acquisition lead on LinkedIn. It’s way more effective. Look for titles like "Talent Acquisition Specialist at Mount Sinai Health System." A quick, polite message there often bypasses the black hole of the general HR inbox. Just don't be annoying about it. One follow-up is professional; three is a red flag.

Benefits, Payroll, and the "Employee Experience"
For current staff, the Mount Sinai Hospital HR department is really about the "Sinai Cloud." That’s the internal Oracle-based system where everything lives. If you need to change your tax withholdings, check your 403(b) contributions, or see how much PTO you’ve accrued after that grueling double shift, you’re going into the Cloud.
The benefits package at Sinai is actually one of the reasons people stay despite the high-pressure environment of NYC healthcare. They offer a "Select" medical plan that, for many employees, has incredibly low out-of-pocket costs if you stay within the Mount Sinai provider network. It’s a "keep it in the family" model. HR manages this, but they often outsource the actual administration to third-party vendors like Empire BlueCross BlueShield or UnitedHealthcare.
Common HR Contact Points (The "Where Do I Go?" List)
- Employment Verification: Don't call the hospital floor. Mount Sinai uses The Work Number. It’s an automated service (Company Code 12045, usually). Banks and landlords know how to use this. HR won't manually write you a letter most of the time.
- Labor Relations: This is a huge wing of their HR. Since many Sinai employees are members of 1199SEIU or NYSNA (the nurses' union), HR spends a lot of time negotiating contracts and handling grievances. If you're a union member, your first stop for a problem isn't usually HR—it's your union delegate.
- Physician Resources: Doctors often have a completely different HR track. The Office of Faculty Affairs handles a lot of the heavy lifting for those at the Icahn School of Medicine. It’s more academic than corporate.
What Most People Get Wrong About Sinai HR
People think HR is there to be your therapist. It’s not. In a massive Tier-1 academic medical center, the Mount Sinai Hospital HR department exists to protect the institution and ensure compliance with grueling New York State Department of Health regulations. They are sticklers for paperwork. If your medical clearance—like your flu shot or PPD test—is one day late, HR will trigger a system lockout. They aren't being mean; they're avoiding massive fines during audits.
The "New Hire Orientation" is another beast. It used to be a big, in-person event at the Guggenheim Pavilion or nearby hotels. Now, it’s largely a hybrid model. You'll do hours of "Mandatory Annual Training" (MAT) modules online. If you're joining the team, do yourself a favor: get your I-9 documentation sorted early. Digital copies rarely suffice; you usually have to show the physical Social Security card or passport to an HR rep at some point in the onboarding process.
Handling the "Under Review" Limbo
It’s the most common complaint: "My status has said 'Under Review' for a month."

Basically, this means you passed the initial ATS screen, and your name is in a digital folder that a recruiter or hiring manager can see. It doesn't mean they have seen it. Mount Sinai is a bureaucratic ship. A department head might want to hire you, but they have to wait for "Position Control" (a sub-sect of HR/Finance) to re-approve the budget for that specific role before an offer letter can be generated.
Sometimes, positions are posted because they have to be, even if there's an internal candidate already lined up. It’s a legal hoop. If you don't hear back within 14 business days, it’s safe to assume they’ve moved on or the role is on a "budgetary hold."
Actionable Steps for Navigating Mount Sinai HR
If you need to get things moving, stop waiting for the phone to ring. Use these specific tactics to break through the corporate wall.
1. Use the Employee Self-Service (ESS) Portal First
If you are a current or former employee, 90% of your needs (W2s, paystubs, address changes) are in the Sinai Cloud/Infor portal. If you’ve lost your login, the IT Help Desk (212-241-4357) is actually who you need, not HR. HR doesn't handle password resets.
2. The 150 East 42nd Street Hub
While many offices are closed to walk-ins, the main corporate HR functions are centered in this building (the Pfizer building). If you are mailing official legal documents or sensitive payroll disputes, this is generally the recognized "HQ" for the health system's corporate side.

3. Reference the Correct Campus
When you do finally get a human on the phone, specify your campus immediately. Mount Sinai South Nassau has a completely different HR team than Mount Sinai West. If you just say "I work for Mount Sinai," you’re going to get transferred to the wrong queue.
4. The LinkedIn "Side Door"
Search for "Mount Sinai Health System Talent Acquisition." Filter by "People." Look for the person who specifically recruits for your department (e.g., "Nursing Recruiter"). Send a Note—not a Connection Request—mentioning the specific Job ID number from your application. This turns you from a number into a name.
5. Verification of Employment (VOE) via The Work Number
Save yourself the headache of trying to find a fax number. Tell your lender to use the "The Work Number" portal. Mount Sinai has automated this to prevent their HR lines from being clogged by mortgage brokers.
Navigating the Mount Sinai Hospital HR department requires a bit of patience and a lot of knowing which digital door to knock on. It’s a system built on efficiency and compliance, which can often feel cold to the individual. But if you have your Job ID, your Employee ID (if applicable), and your specific campus ready, you'll cut through the red tape significantly faster than someone just "calling to check in."
