Employment References: Defamation Risk and Service-Letter Rules

Most employers answer reference calls with dates of employment and job title, and nothing else. The policy is sound, but it is usually adopted without anyone examining what the underlying risk is or what the law in the relevant state actually provides. Several states have gone out of their way to protect employers who give candid references, and a few require an employer to say more than nothing.

Defamation is state law. There is no federal reference statute, and the answer changes at state lines.

What a reference claim requires

A defamation claim against a former employer generally requires a false statement of fact, communicated to at least one third party, made with the fault standard the state applies to a private figure, causing harm. Statements that damage a person in their trade, business, or profession are treated in many states as defamation per se, which affects how damages must be proved.

Three consequences follow directly. Truth is a defense in nearly every state, so the accuracy of the underlying facts is the first line of protection. Statements of pure opinion — that someone was not a strong cultural fit, or that you would not rehire them — are generally not actionable because they cannot be proved false, though an opinion implying undisclosed defamatory facts can be. And the statement must reach someone; a note in a file that nobody outside the company sees is not published.

Adjacent theories travel with the defamation count. Tortious interference with a prospective employment relationship, intentional infliction of emotional distress, and in some states invasion of privacy through false light are pleaded alongside it. The evidentiary center is the same in each: what was said, to whom, and whether the speaker had a basis for it.

Qualified privilege and statutory immunity

The common-law common-interest privilege protects a statement made in good faith on a subject in which the speaker and the recipient share a legitimate interest. A prospective employer asking about a candidate's performance is the textbook case. The privilege is qualified rather than absolute, and it is lost by abuse — knowledge of falsity, reckless disregard for truth, ill will, or publication beyond those with the shared interest.

Many states have supplemented that privilege with a reference-immunity statute. The typical design creates a presumption that an employer disclosing information about a current or former employee to a prospective employer acted in good faith, rebuttable by the employee on a heightened standard — often clear and convincing evidence that the employer knowingly disclosed false information or acted with malice. The categories of protected information vary: job performance, reason for separation, and eligibility for rehire are common; some statutes extend to disciplinary history or workplace violence.

Verify before relying: Every row above describes a design used by some states, not a national rule. A single multi-state employer can face all six frameworks at once, and a reference policy written for headquarters will be wrong somewhere. Confirm the statute in the state where the employee worked before relying on any of it.

Service-letter statutes and compelled self-publication

A small number of states require an employer, on the employee's written request, to furnish a letter stating the nature and duration of the employment and the reason for separation. Missouri's statute is the best known and has generated the most litigation. Where such a statute applies, the safe course is not silence but accuracy: the letter must state a true reason, and a vague or shifting explanation is worse evidence than a candid one, because inconsistency between the letter, the internal file, and later testimony is what a plaintiff builds a case on.

Compelled self-publication is the mirror image. A minority of states recognize that where an employer gives a false reason for termination and the employee is effectively required to repeat it to prospective employers, the employee's own repetition can satisfy the publication element. Most states have rejected the doctrine, and some have rejected it expressly by statute. The practical implication for employers in states that accept it is that a stated reason for termination must be defensible even if it is never shared with anyone outside.

Retaliation and labor-law overlays

The most common federal claim arising from a reference is not defamation at all. Federal anti-discrimination statutes reach retaliation against former employees, and the Supreme Court held in 1997 that a former employee may sue over a retaliatory negative reference. Truth is not a defense to retaliation. A completely accurate statement — that the employee filed a charge, or that the employee was difficult during an investigation — can be unlawful if it was given because of protected activity. The Equal Employment Opportunity Commission treats post-employment conduct affecting a person's job prospects as within the scope of retaliation.

Two labor-law points complete the picture. Statements or references that punish an employee for protected concerted activity implicate the National Labor Relations Board's jurisdiction, and several states have blacklisting statutes with their own penalties. Separately, in a 2023 decision the Board found that broadly worded confidentiality and non-disparagement provisions in severance agreements can themselves be unlawful as to statutory employees. As of mid-2026 that decision continues to shape how separation agreements are drafted, and Board doctrine in this area moves with Board composition — so a template built on pre-2023 language should be re-read rather than reused.

Handling a reference request

1. Route it

   Reference calls go to one designated function. The exposure comes from a former supervisor speaking candidly on a personal call, not from human resources reading a script.

2. Confirm the request is genuine

   Verify the caller and the position. Disclosing performance information to someone with no legitimate interest can forfeit a privilege built on shared interest.

3. Check the separation agreement

   If one exists, it may fix the exact language, name the authorized contact, or impose mutual non-disparagement. The agreement controls over the policy.

4. Check the state

   Identify where the employee worked. That determines whether an immunity statute applies, whether a written statement can be demanded, and whether consent is needed.

5. Stay inside the record

   Say only what the documented file supports. A statement backed by a written investigation finding is defensible; the same statement based on recollection is not.

6. Record what was said

   Log the date, the caller, and the information provided. In a later dispute the absence of a log means the plaintiff's version of the call is the only version.

Where a third-party screening firm gathers references, a separate federal regime attaches. The report becomes a consumer report, and a decision based on it triggers the notice sequence and the adverse action obligations described in FCRA employment background checks. Outsourcing the call does not outsource the compliance.

Preserve early: Once a former employee complains about a reference, the underlying investigation file, performance documents, separation records, and any call log become central. Suspend routine deletion immediately; a litigation hold is the first step, not a later one.

Questions the desk gets

Is a strict dates-and-title policy actually the safest option?

It is the lowest-effort option and it eliminates most defamation exposure, but it is not free. It provides no protection against a retaliation claim if the policy is applied selectively, it does not satisfy a service-letter obligation, and it deprives good former employees of a reference they earned. The realistic middle position is a consistent policy, a single authorized contact, and disclosure of documented facts where a state statute makes candor safe.

Can we say the employee was terminated for cause?

Only if it is true, documented, and the state's framework permits the disclosure. The higher-risk phrasing is characterization — theft, dishonesty, harassment — because those are verifiable factual assertions and each requires evidentiary support. The safer construction states the finding as the record states it: that an internal investigation concluded a specific policy was violated. The standards for building that record appear in workplace investigation scope and records.

Does a signed release in a separation agreement cover future reference statements?

Generally no. A release covers claims existing at signing; a defamatory statement made afterward is a new claim. What the agreement can do is fix the reference language, name the authorized contact, and impose mutual obligations with a defined remedy. Those provisions have to be drafted against current limits on confidentiality and non-disparagement terms, and coordinated with any arbitration provision — see arbitration agreements at work.

A manager gave a bad reference against policy. Is the company liable?

Frequently yes. An employer can be liable for statements made by a supervisor acting within the scope of employment, and a policy that was not enforced is weak evidence that the manager was on a frolic of their own. It matters more that references are routed and monitored than that the handbook contains the correct rule. Train the population that actually receives the calls.

Do we have to tell an employee what we say about them?

Under federal law, generally not — unless a consumer reporting agency is involved, in which case the federal disclosure sequence applies. Several states give employees a right to inspect their personnel files, and a smaller group requires a written separation statement on request. Assume in those states that everything written in the file will eventually be read by the employee.

Where the risk actually sits

Not in the reference call. It sits in the documentation created months earlier — the termination memo written in frustration, the performance review that praised someone the company later called incompetent, the investigation that reached a conclusion without interviewing the subject. A reference is only as defensible as the file behind it, and the file is written long before anyone calls.

Three items are worth fixing this quarter. Identify every state where employees work and confirm which of the six frameworks above applies in each. Re-read the separation-agreement template against post-2022 federal limits on confidentiality and non-disparagement in harassment matters, and against current labor-board doctrine. And confirm that reference calls are routed to one place with a log, because the log is the evidence. Broader workforce obligations, including the wage and audit exposure that often accompanies a contested separation, are indexed on the Employment & Workforce desk and in payroll records and wage-hour audits. Federal wage-hour material is published by the Wage and Hour Division, and general statutory texts are available through the Legal Information Institute.
