Can an Employer Record Audio at the Workplace in Michigan?

Yes, an employer can record audio at the workplace in Michigan, but the circumstances are narrow. If a manager or other company representative is a participant in the conversation, that person can record it without telling anyone else in the room. If no company representative is part of the conversation, recording it without the consent of every participant is a felony under Michigan’s eavesdropping statute, carrying up to two years in prison and a $2,000 fine.¹

When a Michigan Employer Can Legally Record

Michigan operates as a one-party consent state for people who are actually part of a conversation. The Michigan Court of Appeals established this in Sullivan v. Gray, holding that the eavesdropping statute “unambiguously excludes participant recording from the definition of eavesdropping by limiting the subject conversation to ‘the private discourse of others.'”² The court’s reasoning was practical: a participant has always been free to repeat what was said from memory or notes, and a recording is simply a more accurate version of that same account.³

In practice, this means a supervisor sitting in on a disciplinary meeting, a manager on a conference call, or an HR representative conducting an interview can record the exchange legally. No announcement is required under Michigan criminal law. The participant rule is the single most important fact for understanding what employers can and cannot do here.

When Workplace Audio Recording Becomes a Crime

The felony line sits exactly where the participant rule ends. MCL 750.539c makes it a crime for anyone, “present or not present,” to use any device to eavesdrop on a private conversation without the consent of every person involved.¹ An employer who hides a microphone in a break room, a shared office, or a conference room to capture conversations between employees when no manager is present commits a felony. Owning the building, paying the staff, and having a legitimate interest in what employees discuss do not change that.

The relevant question is never whether the employer had a reason. It is whether a company representative was a participant in the specific conversation that got recorded, or whether every participant consented.

Places Audio Recording Is Never Allowed

Separate from the eavesdropping law, MCL 750.539d makes it a felony to install any device for observing, recording, transmitting, photographing, or eavesdropping in a “private place” without the consent of the people entitled to privacy there. This covers both audio and video.⁴ Restrooms, locker rooms, and changing areas are the clearest examples. No security concern, theft investigation, or productivity program justifies a microphone or camera in these spaces.

The penalties escalate:

First offense: felony, up to 2 years in prison and/or a $2,000 fine.
Repeat offense: felony, up to 5 years in prison and/or a $5,000 fine.
Distributing a recording obtained illegally: felony, up to 5 years in prison and/or a $5,000 fine.

Security Cameras That Also Capture Audio

Many Michigan employers run video surveillance in common work areas, which generally raises no issue under state law because the eavesdropping statute targets conversations rather than visual observation of activity in non-private spaces. Adding a microphone changes the analysis completely. The moment a camera captures audio of a private conversation without everyone’s consent, the recording becomes a potential felony under MCL 750.539c.¹

The practical fix is simple. Most workplace surveillance systems can disable audio capture, and for the great majority of employers that is the right default. Turn audio on only when there is a specific, defensible purpose and the consent requirements have been met.

Phone Calls That Cross State Lines

Workplace calls often involve someone in another state, which brings in the federal Wiretap Act (18 U.S.C. § 2511). Federal law also follows a one-party consent rule: a party to the call can record it unless the recording is made for a criminal or wrongful purpose.⁵ The complication is that some states (California, Florida, and Illinois among them) require consent from everyone on the line. Courts have reached different conclusions about which state’s law controls when a call crosses jurisdictions.

The safe practice is to follow whichever state’s law is stricter. For a Michigan employer calling someone in an all-party consent state, that means asking for permission from everyone on the line before recording.

Employees’ Right to Record Under Federal Labor Law

Employers who worry about audio recording often want to prohibit employees from recording too. Federal law limits how far that prohibition can go. The National Labor Relations Act protects employees’ right to engage in “concerted activity” about working conditions, and the NLRB has found that recording can qualify as part of that protected activity when used to document safety hazards, discrimination, or wage disputes.⁶

A blanket “no recording under any circumstances” policy invites NLRB scrutiny. The Board weighs the policy’s impact on Section 7 rights against the employer’s legitimate business justifications, such as protecting trade secrets or client confidentiality.⁷ A rule narrowly aimed at those concerns is more defensible than a sweeping ban that would stop an employee from documenting a supervisor’s conduct.

Protection has limits. An employee whose recording violates Michigan’s criminal law, invades a coworker’s personal privacy, or has nothing to do with working conditions can lose that protection.

How to Record Legally: Policy and Consent

The most reliable way for a Michigan employer to record audio without legal risk is through documented consent. Two tools do most of the work.

A written policy in the employee handbook should identify where recording devices operate, whether they capture audio, video, or both, and how recordings are stored and accessed. An employee’s signed acknowledgment of that handbook establishes documented notice. It does not automatically supply the consent that MCL 750.539c demands for every future private conversation, but it meaningfully weakens any later claim that the employee had no idea monitoring occurred.

Environmental notice reinforces the policy. Visible signs stating that audio recording is in progress put employees on warning. Conversations held in posted areas after that notice have a weaker claim to being “private” for statutory purposes. This matters most for employer-provided tools like business phones and conferencing software, where the expectation of privacy is already lower.

The strongest footing is explicit individual consent. An employee who signs a document specifically agreeing to audio monitoring in designated areas gives the employer the cleanest defense against an eavesdropping claim.

What It Costs an Employer Who Gets It Wrong

Illegal workplace recording in Michigan exposes an employer on two tracks at once.

Criminally, violating MCL 750.539c is a felony with up to two years in prison and a $2,000 fine. Violating MCL 750.539d carries the same first-offense penalty and escalates to five years and $5,000 for a repeat offense or for distributing illegally obtained recordings.⁴

Civilly, MCL 750.539h gives the person recorded three remedies: an injunction stopping further recording, recovery of all actual damages, and punitive damages set by the court or jury. The statute places no cap on punitive damages.⁸ When the recording also violates the federal Wiretap Act, 18 U.S.C. § 2520 allows the greater of actual damages plus the violator’s profits, or statutory damages of $100 per day or $10,000, whichever is larger, plus punitive damages, attorney’s fees, and costs. The claim window is two years from discovery of the violation.⁹ A single illegal recording can produce a five-figure judgment before the actual damages are even calculated.

Public Employers Face an Extra Layer

Government employers in Michigan, including state agencies, public universities, and municipal offices, face the Fourth Amendment on top of the state eavesdropping statutes. Public employees can hold a reasonable expectation of privacy at work, and surveillance must be reasonable given the notice provided, the area involved, and the purpose. Private employers are not bound by the Fourth Amendment, but public ones answer to it in addition to MCL 750.539c and MCL 750.539d.
