Probationary Periods for New Veterinary Hires

A probationary period, an introductory period, a training window — whatever your paperwork calls it, the working idea is the same: a defined stretch at the start of employment with scheduled check-ins and a deliberate decision at the end.

Pick one term, define its length and its check-in schedule in writing, and use the same word in the offer letter, the handbook and the check-in notes.

A label that means different things in different documents is the version that causes problems.

Outside Montana, this page's research verified no primary source — California included — establishing whether calling a period "probationary" changes at-will status.

So treat the window as a management frame — a review schedule with dates — and leave the at-will language in your offer letter and handbook exactly as your counsel wrote it.

The frame and the legal footing are separate documents doing separate jobs.

One line the research did verify is a promise of a term.

In California, Labor Code 2922 treats employment with no specified term as endable at the will of either party on notice to the other — and there, a "specified term" means a period longer than one month.

An offer letter that promises a job for a set period is drafting a different instrument; whether the "probationary" label alone changes anything there is the same open question as above.

If you want a defined term for an associate, that belongs in an employment agreement — our guide to veterinary employment agreements covers that structure.

Montana makes the word itself legally significant, which is why it gets its own section below.

Everywhere else, keep the purpose practical: shared expectations, a structured evaluation, and a decision point nobody has to improvise.

How the window fits with the steps around it — sourcing, screening, offers — is mapped in our veterinary hiring hub.

Probation language tends to leak into benefits copy: "benefits start once you clear probation."

For group health coverage, the label doesn't set the timing — the clock does.

Under the ACA rules (26 CFR 54.9815-2708), a group health plan may not apply a waiting period that exceeds 90 days.

If your window runs 90 days and coverage starts only after the employee completes it, that policy sits right at the limit, so check how the days are counted before you rely on it.

Two drafting habits keep you clear of the edge.

Write health eligibility as date math from the start date — "coverage begins [date]," not "coverage begins when probation is passed" — so the offer letter, the handbook and the plan document tell the same story.

And confirm with your broker or plan administrator how your plan counts the 90 days; this page's research verified the 90-day limit itself, not the counting method.

Everything else — retirement plan eligibility, PTO accrual, CE allowances, staff pet discounts — follows your plan documents and your handbook, and this page's research verified a rule only for the health-plan waiting period.

Whatever waiting periods you set for those benefits, put the dates in writing at hire and apply them the same way for every role.

Consistency is the part you control; confirm the rest with your benefits provider.

The check-in schedule is where the window earns its keep.

At 30 days, orientation is over and the question is fit: does the job as it actually exists match the job that was described, and is the person fluent in your PIMS, your protocols and your pace?

At 60, the question is skill: tasks against the task list, speed, and judgment about when to ask for help.

At 90, the question is the decision itself — confirm, extend with a written reason, or end — made on purpose rather than by drift.

Keep each check-in short, ask the same questions at each one, and write the answers down.

Nothing discussed at the 90-day meeting should be the first time the employee hears it; a person told at day 30 and again at day 60 that something isn't landing is not blindsided at day 90.

Those notes are also the record you rely on if the hire isn't working out — the file builds itself if the meetings happen.

The check-ins only measure what onboarding set — the checklist runs from the signed offer through day 90, and it is where expectations get put in writing in the first place.

For veterinary assistants, the window has a specific deliverable.

Competency is established by your practice, task by task — so the useful artifact of the first month is a per-task record of who was cleared for what, by whom, and when.

An assistant's first 30 days covers building that record, and the 30-day check-in is where you verify it against what the person is actually doing on the floor.

Montana is where "probationary period" stops being a label and becomes a statutory term.

Montana's Wrongful Discharge from Employment Act makes a discharge wrongful only in four situations: retaliation for refusing to violate, or for reporting a violation of, public policy; a discharge that was not for good cause after the employee completed the probationary period; one that materially violated the employer's own written personnel policy; or one made solely for the employee's legal free speech, including on social media.

The period itself has a default.

If the employer does not set a probationary period — or state that there is none — before or when the employee starts, a 12-month probationary period applies by law from the start date.

Silence drafts your policy for you, which is why Montana paperwork is a before-day-one job: decide the length deliberately, or decide there is no probationary period, and put it in writing.

The mechanics have edges.

A Montana employer may extend the period, but only before it expires, and the original period plus any extensions may not exceed 18 months.

A leave of absence — an absence of more than 5 consecutive working days, not counting holidays and vacations — does not count toward the probationary period unless the employer affirmatively elects to include it.

What the period changes is the standard for ending employment.

During the probationary period, either side may end the employment at will, on notice to the other, for any reason or no reason.

Once the employee has completed it, a discharge must be for good cause — reasonable job-related grounds, which the Act defines as failure to perform duties, disruption of the employer's operations, a material or repeated violation of written policies, or other legitimate business reasons.

Contracts sit outside all of this: the Act does not apply to employees covered by a written employment contract for a specific term — an associate veterinarian under a multi-year agreement, for example.

A written contract for a specific term there may itself contain a probationary period and an automatic renewal clause.

If your Montana practice uses agreements for its associates, the agreement, not the Act, sets the exit rules.

In Montana, ending employment inside the window is legally simpler than ending it after — but simpler should not mean unexamined.

The statute is explicit: during a probationary period, employment may be terminated at the will of either the employer or the employee, on notice to the other, for any reason or for no reason.

The same statute that requires good cause once the period is completed makes the period itself at-will, so the calendar matters — the day the period completes is the day the standard changes.

Outside Montana, this page's research found no separate rulebook attached to the label for early endings, so run the decision through the same analysis as any termination.

The reasons you act on can't be reasons the law protects, and the documentation you rely on should exist before the meeting, not after.

Our guide to terminating a veterinary employee walks that sequence in full — the file, the protected-reason check, contract terms for associates, and the last-day access cutoffs.

Practically, three things make a during-probation ending cleaner.

First, the reason: write it down while it is fresh — the check-in notes already are that record.

Second, the meeting: keep it private, brief and scripted, the same way you would handle any separation.

Third, final pay: this page's research doesn't cover final-pay timing, so confirm the timing and any required statement with your state labor agency or payroll provider before the meeting, not after.

The other thing "probation" gets attached to is a credential: the technician transferring a license from another state, the new graduate with an exam date ahead of them, the assistant working through an approved program, the associate whose state license paperwork is still in process.

Handled well, the milestone lives inside the same 30/60/90 structure as everything else.

Handled loosely, it becomes a vague "we'll see where they are in a few months" that nobody can act on.

Put three things in writing at hire: the milestone, the date it needs to happen by, and who verifies it.

Verify rather than assume — our guides to verifying a veterinary license and verifying veterinary technician credentials cover the steps.

Which credential a role requires — and what it permits the holder to do — is a state-by-state question, so confirm the requirement itself with your state board before you write it into an offer.

Decide now what happens if the milestone slips: an extension with a new date, or a separation decision made deliberately.

And separate what the employee controls from what they don't — submitting paperwork is theirs; a board's processing queue is not.

A hire can be performing well and still be waiting, which is exactly why the credential line item should be tracked separately from the performance check-ins.

If the practice is in Montana, the default reaches this use of the window too: a probationary period you never defined in writing runs 12 months by law from the start date.
