Yes — veterinary assistants can work relief or per-diem, filling short-term staffing gaps at practices that need coverage without adding a permanent position.
The job is the same as a staff assistant's; the arrangement is different — you work shifts for practices that don't employ you full time.
This page covers what the work involves, who books it, what pay data actually exists, and the W-2 versus 1099 question to settle before your first shift.
What relief veterinary assistant work is
Relief — or per-diem — assistant work is the same job with a different arrangement.
Instead of one employer and a standing schedule, you take shifts at practices that need coverage for a defined stretch: a surgery leave, a resignation, a busier season.
The practice gets the help without adding a permanent position; you get shifts without a schedule attached.
The duties don't change with the arrangement.
A relief assistant restrains and handles patients, cares for hospitalized animals, turns over rooms and supports the technicians and veterinarians in the room, exactly as a staff assistant does — if you're new to the role itself, start with what a veterinary assistant does.
The labels shift around in job posts — relief, per-diem, as-needed — but they describe the same shape, and per-diem is not part-time: part-time is a standing schedule of fewer hours at one employer, while per-diem fills in around demand with no guaranteed pattern.
The relief arrangement is one this site also covers for veterinarians — relief veterinarian work has its own guide, covering how that market is structured.
The assistant version runs on the same core idea, selling coverage instead of a schedule, but the practical answers differ: who does the hiring, what the pay data supports, and how you get classified.
That's what the rest of this page covers.
Who hires relief veterinary assistants?
Start with where the occupation works.
BLS counts 86% of veterinary assistants and laboratory animal caretakers in veterinary services, 5% in educational services and 1% in scientific research and development services — clinics and hospitals dominate, and the non-clinic slices sit largely in university and research settings that employ the same combined occupation.
Those are the employer types a per-diem assistant meets.
The employer base is wide even within the clinic world.
On October 22, 2026, VeterinaryHires listed 2,429 open veterinary assistant jobs from 450 employers across 48 states and the District of Columbia.
Relief demand comes out of that same base: any practice that employs assistants is a practice that can need one covered for a stretch.
What creates the shift is a gap with an end date — vacation and medical leave, a position open while its replacement is hired, a surgical schedule that outstrips the standing roster for a season.
That end date is the whole deal: the practice is buying coverage, not starting a hiring process, so relief bookings reward assistants who are already findable, already referenced, and already trusted.
What do relief veterinary assistants get paid?
The honest answer starts with the limit of the data: our research found no published source establishing a typical relief or per-diem rate for veterinary assistants.
The federal pay series count employed staff, and the listing medians below are advertised pay on posted jobs, not earnings — neither measures the per-diem shift.
So the defensible way to price relief work is against the staff market it draws from — which is what the numbers below are for.
The national benchmark first.
The median wage for veterinary assistants and laboratory animal caretakers was $38,150 a year, or $18.34 an hour, in the BLS OEWS May 2025 release — a combined federal occupation, so every figure in this section covers clinic assistants and laboratory animal caretakers together.
The lowest 10% earned less than $30,120, and the highest 10% earned more than $49,150.
By industry, the same release splits like this:
| Industry (BLS OEWS May 2025 medians) | Median annual wage |
|---|---|
| Veterinary services | $37,930 |
| Educational services | $47,860 |
| Scientific research and development services | $49,230 |
The two non-clinic medians run higher largely because laboratory animal caretakers concentrate there — read the table as where the occupation works, not as a raise waiting for a clinic-based assistant.
Closer to a clinic shift is the veterinary-services slice: in the same release, the median hourly wage for the occupation in veterinary services (NAICS 541940) was $18.24, with the 10th-percentile annual wage at $29,950 and the 90th percentile at $47,890.
Advertised pay on listings is a separate measure, not directly comparable: in the Q4 2026 release dated October 6, 2026, employers hiring veterinary assistants on VeterinaryHires posted a median of $19.00 an hour across 298 employers and 418 listings stating hourly pay, with the middle half offering $18.00 to $22.00.
The live stats counter, checked October 22, 2026, advertised $19.50 (326 employers, 442 listings).
Listing figures are advertised pay, not anyone's earnings.
To price a relief offer, use those staff numbers as the benchmark of the conversation and compare like for like: what does the same practice pay its own assistants for the identical shift?
Then ask what the relief rate is meant to cover — orienting into an unfamiliar hospital's protocols and absorbing a patient flow you didn't build is work an hourly figure doesn't itemize.
Settle the loose terms before you accept: shift length, notice, and what happens when a shift cancels are agreed shift by shift — there's no benchmark on this page that decides them for you.
Every figure here is staff-market data
W-2 or 1099: how per-diem assistants get classified
The trap comes first, because it's the assumption most likely to cost you: working per-diem does not by itself make you an independent contractor, and neither does working short stints.
Classification turns on how the working relationship actually runs — not on the label on the paperwork, and not on the length of the shift.
The IRS sorts the evidence into three categories: behavioral control, financial control, and the type of relationship.
It is explicit that there is no set number of factors that decides the question — the instruction is to look at the entire relationship and the extent of the right to direct and control the work, and to document the factors used.
The Department of Labor's parallel test is in flux.
As of October 22, 2026, DOL's 2024 independent-contractor rule was still on the books, but DOL said it was no longer applying the rule in its investigations; on February 26, 2026, DOL proposed rescinding and replacing it, and the 60-day comment period closed April 28, 2026 with no final rule announced on the rulemaking page.
The February 2026 proposal would use an economic-reality test built on two core factors — the worker's control over the work, and the worker's opportunity for profit or loss based on initiative or investment — and it stresses that the parties' actual practices matter more than what is contractually or theoretically possible.
For a per-diem assistant, those tests reduce to questions you can ask: who sets the shift times, who directs the work once you're on the floor, whose equipment and protocols you run under, and whether the shift is the same job a staff assistant does.
The more the answers look like employment, the more the relationship looks like employment — which is why "per-diem" settles nothing by itself.
Ask how pay will be reported before your first shift, get the answer in writing, and have a tax professional walk you through what it means on your side.
The same decision looks different from the other side of the desk: how practices think through W-2 vs 1099 relief staff covers the employer's side of these tests.

How to find relief and per-diem assistant shifts
Relief work is a trust purchase: a practice is handing its treatment room to someone it doesn't employ, whose handling it may never have watched.
That shapes the search — the channels that work are the ones where someone can vouch for you.
Start with practices that already know you
Tell the clinics you've worked for — or externed or volunteered at — that you're available for coverage. You're the lowest-risk booking a practice can make: your handling is known, your work ethic is known, and there's no orientation gamble in handing you a shift.Search the job boards for per-diem wording
Per-diem roles can surface through the same channels as staff jobs. Search assistant listings for "per-diem", "relief" and "as-needed", and check open veterinary assistant jobs on VeterinaryHires — the posting's schedule language tells you which roles are coverage and which are standing hires.Ask staffing firms directly whether they place assistants
If an agency or staffing platform serves your area, ask plainly whether it places non-credentialed support staff. The answer changes by market and by firm — ask rather than assume it either way, and don't pay to be listed — a practice or firm that charges you to work is one to walk away from.Set the terms before shift one
Confirm the hourly rate, how pay is reported (the section above), whether the shift is orientation-supported or solo, and what happens when a shift cancels. One written message covering those four points is enough — it turns "we'll figure it out" into terms you can actually plan around.
If the calls don't come at first, that's the channel working as designed: practices book relief help they trust, and trust compounds.
A staff role is where the handling speed and references per-diem work runs on get built — getting in with no experience is its own guide, and standing part-time schedules are a halfway point between the two.
