Employment Agreements for Hygienists and Assistants: What to Include

For a hygienist or assistant, you are choosing between two postures.

The first: an offer letter that states the role, the pay and its basis, the schedule and the contingencies, with employment that has no specified term and either side can end.

The second: a written employment agreement that binds both of you to negotiated terms.

Most hourly staff hires fit the first posture, and it is the simpler one to live with.

The no-specified-term default is not just convention — California writes it into statute: an employment having no specified term may be terminated at the will of either party, on notice to the other (Labor Code 2922).

Other states' default rules come from their own law and court decisions, which this guide's sources did not research.

The verified exception is Montana: under the Wrongful Discharge from Employment Act (MCA 39-2-904), a discharge is wrongful if it was not for good cause and the employee had completed your probationary period.

And at-will is a posture, not a blank check — anti-discrimination laws and state-court doctrines still apply, and neither this guide nor an at-will clause rules on any particular termination.

A written agreement is worth its upkeep when the hire has moving parts an offer letter cannot carry:

• Variable pay. Production or collection components need a written method (more below, and California has a specific rule for commission-style pay).
• Credential conditions. Roles that live or die by a license or permit the state board issues.
• Restrictive covenants. Non-compete or non-solicit terms you have confirmed are usable in your state.
• A specific bargain. A four-day schedule, a shared position, a start-date arrangement you want on paper.

For everyone else, the offer letter does the job — the full anatomy, including the contingencies and the at-will sentence, is the offer letters guide's subject.

One warning travels with either document: whatever you sign sets the floor.

A clause promising a fixed term or a cause standard trades away the simplicity you started with, so sign terms deliberately rather than because a template contained them.

Dentist hires are a different contract altogether — the associate agreement guide covers associate terms.

And if you are still earlier in the process, the dental hiring hub sequences the whole hiring workflow.

When you do paper a staff hire with an agreement, keep it short: the terms that genuinely need binding, and nothing that belongs in your handbook.

A short agreement is easier to read, easier to change, and far less likely to contradict your offer letter or your hire notices.

The clauses that earn their place:

• Parties and position. The practice's exact legal name — including any DBAs — the title, full-time or part-time status, and the reporting line.
• Pay: rate, basis, payday. The same three fields your hire notices require. Write them identically in the letter, the notice, the agreement and the first paycheck; a mismatch between any two is a dispute you drafted yourself.
• The variable-pay method. If any part of compensation tracks production or collections, state the formula, when the amount is earned, and when it is paid. California is the state with a specific rule: when pay involves commissions, Labor Code 2751 requires the contract to be in writing and to set out how commissions are computed and paid, with a signed copy given to the employee and a signed receipt obtained. Whether a given hygiene production plan counts as a commission under that rule was not settled in this guide's sources — so put the method in writing either way, and confirm the treatment with employment counsel before relying on a handshake.
• Schedule expectations. The days and hours you expect and who can change them. Write expectations, not guarantees — the difference is the next section's subject.
• Credential conditions. The license, registration or permit the role requires, as a condition that lasts through employment, not just the start date. Clause design is below.
• Confidentiality. Patient information and practice records. This is the durable protection: Minnesota's non-compete ban, for one, expressly does not cover confidentiality and trade-secret agreements.
• The term and the termination standard. Say once, plainly, whether employment has no specified term or a fixed one, and whether separation is at will or for cause. The expensive agreements are the ones where the letter says one thing and the agreement another.

The clauses that cause trouble share a shape: each one promises more than the practice can sustain or penalizes the employee for leaving.

Four patterns cover most of the damage.

• Fixed terms. A two-year term converts an ending into a broken promise: if the fit is wrong at month four, you have promised the other sixteen. Leave the term open unless you are getting something concrete in return, and if you do fix a term, reconcile it with the at-will statement elsewhere in your paperwork so the documents do not contradict each other.
• Guaranteed hours. A weekly minimum in the agreement is a fixed cost that stays on the books when patient volume does not fill the chair. If you use one to close a strong candidate, define in writing how the guarantee is calculated — what counts toward it — and exactly when it ends.
• Liquidated damages and departure fees. California draws the line in statute: AB 692 (Business and Professions Code 16608) bans most stay-or-pay terms, and for contracts entered into on or after January 1, 2027 it is unlawful to require a worker to repay a debt, or to impose a penalty, fee or cost, if employment ends — and "penalty, fee, or cost" expressly includes a retraining fee, a replacement hire fee, a quit fee, liquidated damages and lost profit. If your template makes a departing hygienist owe the practice money, have that clause reviewed before the next California hire.
• Non-competes aimed at hourly staff. A clause with real state-law downside in a staff packet. Virginia Code 40.1-28.7:8, for example, bars employers from entering into, enforcing or threatening to enforce a non-compete with any "low-wage employee" — a definition that includes any employee entitled to FLSA overtime, regardless of earnings. What your state allows, and what it still permits you to protect instead, is the non-competes guide's subject.

Whichever document you use — offer letter or agreement — the states verified in this guide's sources require a formal written notice of pay at hire, and New York's requirement cannot be waived.

A clause in the contract is not a substitute for the notice.

New York.

Labor Law 195(1) requires a written notice at the time of hiring stating the rate or rates of pay and the basis — hour, shift, day, week, salary, piece, commission or other — plus allowances claimed, the regular payday, and the employer's name, DBA names, address and phone.

You must obtain a signed and dated written acknowledgment, in English and the employee's primary language, and keep it for six years.

The New York Department of Labor confirms the notice may be included with offer letters or employment agreements given to new hires, but it must be on its own form, and a worker cannot waive it.

Notices are also due when the information on them changes; on language, the Department requires the primary-language version only where it provides a template in that language — otherwise English is sufficient.

California.

Labor Code 2810.5 requires, at the time of hire, a written notice to each non-exempt employee covering pay rate(s) and basis, the regular payday, the employer's name, address and phone, the workers' compensation carrier, and paid sick leave rights, among other items.

Overtime-exempt employees fall outside the notice — which of your roles are exempt is its own analysis, and the exempt vs. non-exempt guide walks it.

Changes to the notice information require written notice within seven calendar days, unless the change appears on a timely wage statement or another required writing.

This is not a survey of every state: the other states' notice laws were not researched for this guide, so confirm your own state's rules with your state labor department before the next hire.

The full hire-notice comparison, including Texas's workers' compensation notice, is in the offer letters guide.

The practice point survives everywhere: the pay clause in any agreement should restate the notice exactly — same rate, same basis, same payday.

For clinical staff, the agreement should state the credential premise outright: employment is conditioned on holding — and keeping current and unrestricted — the license, registration or permit your state requires for the role.

The requirement itself comes from the state, not from your contract; the clause's job is to put both of you on the record about it.

Licensure is a board matter.

Maryland, for example, requires dentists and dental hygienists to be licensed by the State Board of Dental Examiners under the Health Occupations Article (HO 4-301) before practicing.

Which credentials each role needs — and whether assistants in your state carry a registration or permit at all — is state-specific, so confirm the list with your state dental board rather than copying another practice's template.

A workable credential clause does four things:

• Names the specific credential(s) the role requires.
• Requires the employee to tell you promptly of any lapse, restriction or board discipline.
• Lets you verify the credential with the issuing board, at hire and during employment — how to run that check is the license verification guide's subject.
• Makes continued employment depend on the credential staying current, not just the start date.

Keep the clause at that level.

Which clinical tasks each credential lets the holder perform is scope-of-practice law, and it varies by state — confirm it with your state dental board instead of encoding task lists into the agreement, where they will go stale.

Whatever you signed at hire, changes start with writing.

For at-will staff hired on an offer letter, a rate or schedule change is a short written update the employee acknowledges — and where a notice statute applies, the update rules are concrete.

In California, changes to the 2810.5 notice information require written notice within seven calendar days, unless the change appears on a timely wage statement or another required writing.

In New York, a notice is due when the information on it changes.

A signed agreement changes the mechanics.

Changes are cleanest when the employee signs the amendment — a unilateral edit to a signed contract is an invitation to argue about what was agreed.

And a contract that fixed a term or guaranteed weekly hours has already limited how freely the practice can adjust; that is the strongest argument for leaving both open at the outset.

The document you sign at hire sets how easily you can adapt in year two.

Build the habit into the calendar: review staff agreements once a year, re-issue the pay notices your state requires when details change, and get the acknowledgment back before the change takes effect.

When the offer letter, the agreement, the handbook and the notices all say the same thing, a pay dispute has nothing to attach to.
