Often, yes. Washington law imposes no general duty on a detective to tell an employer that a worker is under criminal investigation, and none to tell the worker either. What the law regulates is intrusion, not notice. The limits bite when officers want to record a private conversation or get into places and records you have a right to keep private, and they come with conditions, deadlines, and paperwork. A Seattle criminal defense attorney can tell you which side of that line your situation falls on, and Jennifer Horwitz can step in before any charge is filed.
Washington’s Rule Is About Intrusion, Not Notice
Article I, Section 7 of the Washington Constitution is one sentence long. It says that no person shall be disturbed in “his private affairs, or his home invaded, without authority of law.” That line, found in the Washington State Constitution, is where every question about what investigators may do here starts.
Notice what it does not say. It does not ask whether anyone told you, or told your employer.
Washington’s recording statutes are narrower still. By their terms, they reach intercepting and recording private communications and conversations. They do not speak to an officer noting who arrives, who leaves, and who a person meets in a parking lot. Whether a particular method of watching intrudes on a private affair under Section 7 is decided case by case.
Sustained or technologically assisted surveillance raises different questions than an officer on a public sidewalk. The statutory protections engage when investigators want to capture what is said rather than what is seen.
The notice those statutes do require comes from a court after the fact rather than from a detective at the outset. The notice rules depend on which statute was used. When a judge approves a recording under the main one-party consent statute, the court generally must notify the person named in the approval within a reasonable time, and no later than 30 days after the approval ends. A court may delay or skip that notice for good cause.
The other two routes described below work differently. The emergency court order statute has no notice requirement at all. The agency head route requires notice only if a judge later finds the recording lacked probable cause. Even then, the notice generally is not mailed until six months after that finding.
So an investigation can run for weeks while the employee and employer both stay in the dark. The useful question is not who was supposed to tell you. It is what investigators actually did, and whether they had authority.
Recording a Private Conversation at Work Normally Requires Everyone’s Consent
Washington is an all-party consent state, and the statute is unusually direct about who it binds. It makes it unlawful to intercept or record a private conversation without the consent of every person taking part, and it lists “the state of Washington, its agencies, and political subdivisions” right alongside individuals, partnerships, and corporations. A city police department is part of a political subdivision, and the State Patrol is a state agency. The rule reaches officers, not just coworkers.
There is one important caveat. Federal law lets federal agents record a conversation when one participant consents, without a judge’s approval. But where the recording is used matters. In State v. Williams, the Washington Supreme Court held that recordings federal agents made in Washington without following the state’s consent law could not be used in a Washington state prosecution. A recording made for a federal case can raise different questions than one offered in state court.
At work, investigators often want to capture what people say, not just what they write. Whether a conversation counts as private depends on the circumstances. A closed-door meeting with a supervisor, or a call from a desk phone, is a far stronger candidate than a passing remark in an open hallway. The word “normally” matters, because the statute has exceptions.
Three Main Ways Police Can Get Permission to Record
Washington’s recording law has several exceptions. These three are the ones most relevant to police investigations, and they are not equally narrow.
Emergency Court Orders for Serious Threats
A superior court judge may issue an interception order without notice to the person being recorded, but only if the state attorney general or a county prosecuting attorney applies under oath. The grounds are narrow. There must be reasonable grounds to believe that national security is endangered, that a human life is in danger, or that arson or a riot is about to be committed.
There must also be reasonable grounds to believe the interception will yield evidence essential to preventing that harm, and no other means of getting the information readily available. The order is effective for 15 days, and the issuing court may renew or continue it for an additional period of up to 15 days. This kind of order is meant to prevent harm, not to gather evidence. Information obtained under it generally cannot be used in a Washington civil or criminal case, except in limited national security prosecutions.
Agency Head Approval in Drug and Commercial Child Sexual Abuse Cases
The chief law enforcement officer of an agency, or a designee above the rank of first line supervisor, may authorize recording when at least one party consents and probable cause exists. That route requires probable cause that the conversation involves:
- The unlawful manufacture, delivery, sale, or possession with intent to manufacture, deliver, or sell controlled substances, legend drugs, or imitation controlled substances, OR,
- The commercial sexual abuse of a minor and the related promoting offenses.
It requires a written report signed at the time of authorization, is valid for no more than 24 hours, may be extended not more than twice for consecutive 24-hour periods, and goes to a judge for review afterward.
Judge-Approved Recording With One Person’s Consent
A judge or magistrate may authorize an officer to record a conversation the officer is part of, or one in which another participant has agreed in advance to the recording. That route requires probable cause to believe the nonconsenting party has committed, is engaged in, or is about to commit a felony. The authorization runs no more than seven days and may be renewed for additional seven-day periods.
The first two routes do not reach an ordinary theft or fraud investigation. The third one does. That makes a cooperating coworker wearing a recorder a realistic possibility in any felony case. In a suppression hearing, the fight often turns on whether the proper authorization was obtained before the recording began and whether its conditions were followed.
These limits have teeth. With narrow exceptions, a recording made in violation of Washington’s consent rule cannot be used as evidence in any civil or criminal case in the state, and breaking that rule is a gross misdemeanor. The agency head authorization route carries even steeper penalties. Intentionally recording in violation of that statute is a Class C felony.
If a judge reviewing the authorization, or a court ruling on a motion to suppress, finds that the required probable cause was missing, and the authorization was also made without a reasonable suspicion that the conversation would involve those offenses, the agency owes the person who was recorded $25,000 in exemplary damages. That is on top of any other damages the law allows.
When Police Need a Warrant or Your Employer’s Cooperation
Watching you from a public place is one thing. Getting into your workspace or your files is another. Washington courts hold that when an officer notices something from a place the officer is lawfully allowed to be, no search has occurred. But in some situations, Washington’s constitution protects privacy more broadly than the federal Fourth Amendment. For example, the state Supreme Court has held that police need a warrant to attach a GPS tracker to a vehicle.
When investigators want something from inside the workplace, such as business records, a company computer, or a look inside an office, they generally need a search warrant, a subpoena, or the business’s cooperation. Whether you personally can challenge that kind of search depends on the circumstances, such as who owns or controls the space, account, or device and what workplace policies say.
Any of those routes tends to bring your employer into it. When officers take property under a Washington search warrant, they must leave a copy of the warrant and a receipt for anything they take.
Can Police Interview Your Coworkers Without Telling You?
Yes, and it is one of the most common ways people learn they are under investigation. Detectives may approach supervisors, colleagues, or clients and ask about schedules, system access, accounts, or behavior. Nothing obligates them to tell you first, or to route the request through your employer.
The instinct to get ahead of it is where cases go badly wrong. Washington makes it a Class C felony to attempt to induce a person you have reason to believe may have information relevant to a criminal investigation to withhold that information from law enforcement or to testify falsely. No charge has to be filed. Nobody has to have been subpoenaed. And the statute treats each attempt as a separate offense, so a short run of messages asking one nervous coworker to stay quiet can become several felony counts.
What Not to Do if You Think You Are Being Watched
The steps that feel protective usually create a second case, one with nothing to do with the original investigation. Do not confront the people you believe are watching you, or ask your employer to confront them. Do not ask coworkers what investigators wanted, or suggest what they should say.
Do not delete messages, clear a history, shred paperwork, or wipe a device. Washington treats destroying, concealing, removing, or altering physical evidence as a gross misdemeanor. The statute reaches an article, object, document, record, or other thing of physical substance. Courts have not clearly settled whether that covers a purely electronic message, but the risk is real. In a 2025 unpublished opinion, a Washington appeals court upheld an attempted tampering conviction against a man who, after his arrest, asked someone to remotely erase his phone. The charge requires that the person have reason to believe an official proceeding is pending or about to be instituted, act without legal right or authority, and intend to impair that evidence in the proceeding.
A police investigation is not by itself an official proceeding. But the law also covers a court case that is about to begin. So once you have reason to believe charges are coming, destroying evidence can be a crime even before anything is filed. In a federal investigation, the stakes are much higher. Federal law makes it a felony, punishable by up to 20 years in prison, to destroy, alter, or conceal records or documents with intent to obstruct a federal investigation. That law applies even to an investigation that has only been contemplated.
Do not agree to a quick conversation to clear things up. The state constitution says no person shall be compelled in any criminal case to give evidence against himself. That protection does little for you if you volunteer the evidence instead.
None of this is about concealment. It is about refusing to hand a prosecutor a charge that the underlying investigation never would have produced.
