Per Diem Nursing

A per diem nurse works shift by shift rather than on a set schedule. The facility calls when it is short, whether for a sick call, a vacation, or a stretch when a unit is simply busy, and the nurse accepts or declines. The name is Latin for "by the day," and it describes the commitment as much as the pay.

The hourly rate is normally higher than staff pay for the same work. Almost nothing else comes attached: no employer health insurance, no paid time off, no retirement contribution, and no guaranteed hours. That trade is the entire decision.

How much of nursing this is

Nobody counts per diem nurses as such, but two measures bracket it.

Nurses employed by staffing agencies rather than by a facility, which covers per diem placement and travel contracts together, went from 57,270 registered nurses in 2019 to 130,890 in 2023.

Nursing homes report their contract hours to Medicare, so their agency use is public. Contract staff were 3 to 4 percent of nursing home nurse hours before the pandemic, peaked in 2022, and were 7.5 percent in early 2024, down from 10.1 percent a year earlier. The spread across states is extreme: 25.1 percent of nurse hours in Vermont in mid-2025 against 1.0 percent in Alabama.

On the supply side, the pool is wider than for travel work. Of the 375,448 registered nurse profiles on this site, 45.7 percent say they will take per diem shifts against 38.9 percent for travel. The two do not follow the same map: willingness to travel is highest in Montana, Mississippi and Alabama and lowest in New Jersey and Connecticut, while per diem willingness is highest in Rhode Island, Hawaii and New Jersey. Flexible work reaches nurses who will not leave home.

What the trade actually consists of

On the nurse's side there is control of the calendar, the ability to decline a shift without explanation, exposure to several units or facilities, and a higher rate per hour worked. Against that sits income that varies month to month, benefits bought out of pocket, no protection against a quiet stretch, and no seniority accruing anywhere.

On the employer's side there is coverage that can be turned on for one shift and off again, without carrying benefit costs or a permanent post. Against that sits a nurse who may decline, less familiarity with the unit than a staff member has, and an hourly rate above the staff line.

How it differs from neighbouring arrangements

Per diem is often used loosely for anything that is not a full-time staff post, which obscures three genuinely different arrangements.

A per diem nurse commits to no fixed hours and is paid a premium rate per shift, either directly by the facility or through an agency. Some employers require a minimum number of shifts a month to stay on the roster.

A float pool nurse is usually an employee of the hospital with a regular schedule, assigned across units rather than to one. The flexibility belongs to the employer. See float pools and internal resource pools.

A travel nurse takes a fixed-term contract, normally thirteen weeks, away from home, with housing or a stipend in the package. The commitment is for the length of the contract rather than for a single shift.

Part-time staff employment is different again: fewer hours, but scheduled, and often with prorated benefits.

Who employs you, and what that changes

Most per diem nurses are employees, either of the facility that keeps them on its own per diem roster or of the agency that places them. Being an employee without benefits is not the same as not being an employee: payroll taxes are withheld, and wage and hour protections apply to the shifts worked, including the overtime rules that depend on whether the post is hourly or salaried. See nurse overtime.

Where an agency is the employer, its contract terms deserve the same reading a travel contract gets, particularly on cancelled shifts and on any restriction on working elsewhere. Several states now regulate those terms directly. See nurse staffing agencies.

Some arrangements engage nurses as independent contractors instead, which moves payroll taxes and much of the risk onto the nurse. Whether that classification holds depends on how the work is actually controlled rather than on what the contract calls it, so it is worth understanding before signing rather than at tax time. See per diem employment status.

Hours also interact with benefits eligibility. Under the federal health law, a large employer's full-time employee is one working an average of at least 30 hours of service a week, or 130 hours a month, measured either month by month or across a longer look-back period. A per diem nurse who consistently picks up that much work can cross into the group an employer has to offer coverage to, which is a question worth asking rather than assuming either way.

What it pays

There is no national wage survey that reports per diem rates separately. Federal occupational wage data covers registered nurses as a single occupation and does not break out shift-by-shift work, so any figure quoted for per diem pay comes from job postings or agency marketing rather than from a survey.

The closest measured comparison is by employer type. In 2023 a registered nurse employed by a staffing agency earned a median $48.30 an hour against $38.37 for one employed by a nursing home, a gap that widened from six percent to twenty-one percent in four years. The agency figure covers travel work as well, so treat it as the shape of the premium rather than a quote.

The rate is set above the local staff rate for the same role precisely because nothing else is attached to it, and it varies by region as much as staff pay does. The state-by-state spread in registered nurse pay is the right starting point for judging a local per diem offer, since the premium is applied on top of a local market rate.

Two costs belong in the comparison with a staff job. Health coverage and retirement matching are worth real money and are the nurse's own expense here. And hours are not guaranteed, so an annual figure calculated from an hourly rate and a full year of shifts is a projection, not a salary. The arithmetic is set out in per diem nurse pay.

Who it suits

Per diem work rewards nurses who want control over when they work and can absorb a quiet month: nurses with other commitments, nurses covered by a spouse's health plan, nurses adding shifts on top of a staff post elsewhere, and nurses stepping back from full-time work without leaving the profession.

It punishes anyone who needs a predictable paycheque or employer benefits.

The retirement connection employers miss

The single largest force pulling nurses out of the profession is retirement, not burnout. Retirement was named by 61.4 percent of nurses who said they intended to leave, and it now sits third among the reasons nurses give when they resign a post. See nurse turnover and retention.

Retirement is rarely all-or-nothing. Nurses stepping back from a full-time roster frequently want to keep working reduced hours, which is exactly what a per diem roster offers. An employer with a flexible roster is recruiting from a population that a full-time-only employer cannot reach, including the nurses just leaving a competitor's full-time schedule. Given a median nurse age of 50 and a shrinking under-30 cohort, that population is growing. See building a per diem roster.

Long-term care has a structural advantage in reaching that group, because its hours are more predictable than a hospital's. See nursing home staffing requirements.

What per diem staffing does not solve

Shift-by-shift cover fills a gap in a rota. It does not substitute for the permanent staffing a unit is built around. A nurse new to a unit each shift carries the same patient load with less knowledge of local practice, the patients, and where things are kept, which is one of the reasons staffing research measures continuity and skill mix rather than headcount alone. See nurse staffing and patient outcomes.
