Updated September 2026. General information only. Constitutional, labor, civil-service, collective-bargaining, and agency rules must be analyzed for the specific employee and interview.
A public employee called into an investigatory interview may hear “Garrity,” “Miranda,” and “Weingarten” used as though they mean the same thing. They do not. Each doctrine addresses a different risk: compelled self-incrimination, custodial police interrogation, or union representation during an investigatory interview.
Garrity: compelled statements by public employees
Garrity v. New Jersey involved public employees required to choose between self-incrimination and job loss. The Supreme Court held that statements compelled under that threat could not be used against the employees in a criminal prosecution. The official opinion is available in the U.S. Reports, 385 U.S. 493.
Garrity is not a general right to refuse every employer question. A public employer may be able to require answers to narrowly job-related questions when the constitutional protection against criminal use is respected. Whether statements were actually compelled—and the scope of any derivative-use issue—can become contested.
Miranda: custodial interrogation
Miranda v. Arizona requires warnings before custodial interrogation for purposes of the prosecution’s case-in-chief, subject to later doctrine and exceptions. Custody and interrogation are separate questions. A workplace interview is not automatically custodial, and a person can be in a coercive employment situation without being in Miranda custody. Read the official Miranda opinion, 384 U.S. 436.
Weingarten: requested union representation
Under federal labor law, a union-represented employee may have the right, upon request, to representation at an investigatory interview the employee reasonably believes could lead to discipline. The employer is not generally required to guess that the employee wants a representative. The NLRB’s official Weingarten Rights guide explains the doctrine and the representative’s role.
A side-by-side practical comparison
| Doctrine | Core setting | Primary protection | Important trigger |
|---|---|---|---|
| Garrity | Public employment | Protection against criminal use of compelled statements | Compulsion tied to job consequences |
| Miranda | Criminal investigation | Warnings before custodial interrogation | Custody plus interrogation |
| Weingarten | Union-represented workplace | Representation during qualifying interview | Employee request and reasonable fear of discipline |
Administrative and criminal investigations can run in parallel
An internal-affairs matter may overlap with a criminal investigation. Different investigators can share information, intentionally or inadvertently. The source of questions, warnings given, employment orders, and downstream use of statements should be documented. A label on a form does not replace analysis of what actually occurred.
Questions to ask before answering
- Is this interview administrative, criminal, or both?
- Am I ordered to answer, and what employment consequence follows refusal?
- What warning or written directive has been given?
- Who will receive the statement or recording?
- Am I union-represented, and have I requested a representative?
- Do policy, civil-service rules, a law-enforcement officers’ bill of rights, or a collective-bargaining agreement add protections?
- May I consult personal counsel before the interview?
Do not rely on magic words
“I invoke Garrity” does not automatically immunize a voluntary statement. A Garrity warning does not itself answer whether questions are sufficiently job-related. Miranda warnings do not transform every employment interview into a criminal interrogation. And Weingarten rights generally require a request in a qualifying union setting.
Preserve the record
Keep the interview notice, policy, warning, order to answer, union request, recordings, notes, and follow-up communications. Do not secretly record without first understanding applicable law and policy. After the interview, document who attended and any direction about confidentiality or further contact.

Ask Chris: Which right should I invoke?
First identify the interview: employer or police, public or private employment, union or nonunion, voluntary or ordered. The correct protection follows from the actual setting, not the most familiar acronym.
