Per-diem nursing pools — rosters of nurses who commit to a minimum number of shifts per month and take premium hourly pay with no benefits or guaranteed hours — are the flexible tier most New York hospitals now build their staffing plans around, sitting between the full-time core and external travel contracts. Their growth tracks the repricing of agency labor after 2022: average travel RN pay fell 11.3 percent during 2023, per Vivian Health's published pay-trend reports, pushing systems and nurses alike toward local per-diem arrangements instead.
Health Work NY publishes information, not career advice. This article explains the mechanics — how internal pools differ from agency per-diem, how the rates are set, what the commitments and cancellation rights actually say, and where the trade-offs fall for nurses and for the hospitals. Rate figures appear only with their named source and year; a staffing agency's posted rate is an agency's figure, and a hospital's scheduling policy is the employer's own document.
What is the difference between an internal pool and agency per-diem?
An internal per-diem pool is the hospital's own employment category: the nurse is a direct employee, scheduled shift by shift against a monthly minimum, covered by the facility's policies, union contract where one exists, and the facility's liability structure, per hospital employment descriptions. Agency per-diem places the nurse on a staffing firm's payroll, working short-term assignments inside the same facilities at rates the agency sets, per industry descriptions of the model. The practical differences are taxes and benefits — internal pools can carry partial benefits eligibility, agency work does not — and leverage: agency nurses can walk across town between assignments, while internal pool nurses keep one employer's scheduling preferences. New York's staffing-committee statute treats both groups as staff to be counted in the annual plan, per Public Health Law Section 2805-t's plan requirements.
How are per-diem rates set?
Internally, the hospital sets a differential — a percentage or dollar add-on to the base hourly rate for the same title — typically ranging higher on nights, weekends, and hard-to-fill units, per hospital wage schedules and union contract rate charts. The differential is published in the facility's wage documents and, in unionized hospitals, is negotiated: per-diem differentials appear as contract line items, per union contract summaries. Agency rates are set by the market: the agency bills the hospital an hourly rate and pays the nurse a cut, with the spread covering the firm's margin, workers' compensation, and payroll costs, per industry descriptions. Neither rate is guaranteed over time — internal differentials move with contract negotiations, and agency rates reprice assignment by assignment, which is why the same nurse can watch her rate fall between contracts, as the 2023 and 2024 travel-market repricing demonstrated, per the platform-published trend data.

What do the commitments and cancellation rights say?
The standard internal arrangement requires a monthly shift minimum — commonly expressed in shifts rather than hours, with weekend and holiday quotas — in exchange for the differential, per hospital per-diem policy descriptions. Cancellation cuts both ways: hospitals can typically cancel a per-diem shift up to a few hours before start without pay, and nurses who fall short of their monthly minimum can lose the differential or, after repeated shortfalls, the pool status, per the same policies. Agency per-diem is looser still: no monthly minimum, but no cancellation protection either, and assignments can end with notice defined by the contract rather than by employment law's progressive-discipline framework. Seniority, scheduling priority, and transfer rights generally do not accrue the way they do for full-time lines, per standard hospital plan structures and union contract summaries.
Do per-diem nurses get unemployment or workers' compensation?
Workers' compensation applies either way — internal pool nurses are employees of the hospital, and agency nurses are employees of the staffing firm, each covered by the respective employer's policy, per New York's mandatory coverage rules. Unemployment eligibility depends on the wage base and hours worked for the employer in the base period; a nurse working only sporadic per-diem shifts may fall short, and an agency nurse's claim runs against the agency as the employer of record, per the state Department of Labor's published explanations. Health insurance is the sharpest difference: internal pools may extend eligibility at a threshold of average hours, per plan documents, while agency assignments almost never do, which is why some nurses patch together coverage through a spouse's plan or the state marketplace.
Why hospitals keep building pools anyway
For the employer, the pool converts a fixed cost into a variable one, and the staffing-committee law makes the conversion auditable: a plan filed under Section 2805-t commits to staffing levels, and a per-diem band lets the hospital meet them without carrying idle full-time lines through seasonal troughs, per the plan requirements' structure. Unions read the same arrangement as shifting risk onto workers — the New York State Nurses Association's position on contingent scheduling, stated in its public advocacy — and negotiate to cap pool sizes and preserve differentials. Both accounts describe a roster that now has three tiers instead of one, and the terms of each tier — the minimums, the differentials, the cancellation clocks — are where the real negotiation happens.
How did the travel-market collapse change pool hiring?
The repricing of agency labor after 2022 redirected both sides of the market toward local per-diem, per the platform-published pay trends cited above: hospitals that had leaned on travel contracts during the surge shifted the flexible band in-house or to local agencies, cutting housing stipends and recruiter margins from the bill, while nurses who had traveled concluded that steady local premium rates without relocation beat falling travel packages. The result, visible in staffing-committee plans filed since 2023, is a larger per-diem band inside hospital rosters, per the plans' own structures. The arrangement is cheaper for the employer and more predictable for the nurse than travel — and it inherits the per-diem model's original weaknesses, including cancellation exposure and thin benefits, unchanged from before the pandemic.
