What are employee rights in a workplace investigation?

As employees, you have rights during a workplace/human resources investigation. These can be especially strong if you are a public employee or have a collective bargaining agreement.

Regardless, your employer must follow company policies during the internal investigation, such as:

• providing you with notice and an opportunity to defend yourself and
• access to all evidence used against you.

Your employer also cannot break the law while investigating you for wrongdoing. Therefore, you have legal protections against:

• retaliation,
• discrimination,
• wrongful termination, and
• harassment.

In this article, I discuss what you need to know about your rights during a workplace investigation:

Employee Rights under the Employment Contract

The procedures for an internal workplace/HR investigation are often detailed in your employment contract or your employee handbook. These provisions vary by employer. However, they generally require that all workplace investigations:

• be performed promptly,
• give you an opportunity to be heard,
• forbid decision-makers from having a conflict of interest in the outcome,
• give you access to information or subject matter that is being used against you in the investigation,
• give you access to your personnel record upon request,
• give you access to reasonable accommodations for your disability (though your employer may request medical documentation), and
• protect you from termination or other disciplinary action if no evidence of wrongdoing is found.

Additional Recommendations

You are advised to have your own attorney be with you during any interviews and look over any documents your employer asks you to provide. If you cannot have an attorney, request that a witness be present (though your employer may refuse this). The HR representative may say they are on your side, but they are not: They work for your employer.

Some employers also ask you to sign a document agreeing to participate in and cooperate with your investigation, but you are not required to sign it. Have your attorney look it over before signing anything.

You can always request to see your “investigation record,” which includes any interview notes or other documents related to your case; however, your employer does not have to show you this record if they choose not to discipline you.

Ultimately, the terms of your contract determine your contractual rights during the internal investigation. Your employer has to comply with these rights and obligations. If your employer violates them, you may have legal recourse.

Legal Rights during an Internal Investigation

State and federal employment laws provide numerous legal rights to workers who are the target of a workplace investigation.

For example, your employer cannot take an adverse employment action against you through an internal investigation because you:

• filed a discrimination claim or a harassment complaint,
• reported a violation of the law that is happening in the workplace, like fraud, to law enforcement,
• requested reasonable accommodations for a disability, or
• acted as a whistleblower.¹

If your employer violates any of these rights, you can often file a lawsuit against them. In some cases, simply meeting with HR to discuss your concerns can resolve the issue.

You also have a legal right not to participate in the investigation. However, if your employment contract requires you to cooperate and answer questions honestly, invoking this legal right often leads to termination.

While refusing to cooperate can stop a workplace investigation into potential criminal activity, your employer may forward its investigation report to law enforcement to continue the investigation process.

If you are under a workplace/HR investigation, you have legal rights.

What Employers are Forbidden from Doing

During an internal investigation, employers cannot violate your privacy rights. If they do commit an invasion of privacy, it can lead to a lawsuit.

Some of the most common examples of employers violating your privacy rights during a workplace investigation are:

• searching through your personal phone without your consent,
• demanding your personal passwords and log-in information,
• demanding your confidential health records,
• recording phone calls or interviews in violation of your state’s wiretapping laws, or
• monitoring your workplace activity in ways that are not contemplated by the employment contract.

However, many private-sector employment contracts anticipate these situations and give employers wide latitude to monitor employees or search their belongings in the workplace. For example, employment contracts frequently:

• give employers the power to monitor your computer usage,
• provide access to your work email, and
• state that your belongings can be searched when brought to the worksite.

If your employer asks you to sign a confidentiality agreement, have an attorney look it over before deciding whether to sign. Even if you do sign it, there are situations where you may be able to break confidentiality – such as to report workplace harassment or discrimination.

The terms of an employment contract are generally more generous to employee privacy if you are subject to a collective bargaining agreement or a public employee. In these cases, it is often wise to talk to your union representative or to seek your own legal counsel.

What Triggers Workplace Investigations

Workplace investigations are generally triggered when your employer learns of potential workplace misconduct. That misconduct can be anything from:

• allegations of sexual harassment,
• claims of discriminatory conduct,
• reports that you are contributing to a hostile work environment,
• signs that you are defrauding the company, or
• indications that you are violating company policy in some other way.

Your employer may initiate an investigation or hire an outside investigator after:

• a coworker files a complaint with the human resources department,
• your supervisor reports you for a workplace violation, or
• an audit uncovers evidence of misconduct.

Oftentimes, by the time you are made aware of the ongoing investigation, it will have progressed beyond its preliminary stages. Suppose you are notified of an ongoing investigation and are requested to provide testimony for it. In that case, it often means that it is nearing its conclusion and that there is enough evidence against you from other key witnesses to support its allegations and impose corrective actions.

Suing Employers over an Investigation

If your employer violates your rights during an internal workplace investigation, you may have grounds for a lawsuit. Some common lawsuits that get filed after an internal investigation are:

• wrongful termination for being let go after an investigation that failed to comply with company policies,
• retaliation for investigating you because you engaged in legally-protected activities, or
• defamation, if your employer spreads false information about you.

Common triggers of workplace investigations are allegations of discrimination, harassment, or fraud.

Frequently Asked Questions (California-Specific)

Can I refuse to answer questions during a workplace investigation?

You can, but it is highly risky if you work for a private company. In California, because it is an “at-will” employment state, employees generally have a legal duty to cooperate with lawful workplace investigations. Refusing to participate can be classified as insubordination, giving your employer legal grounds to fire you on the spot.

Note: Public-sector and government employees have special constitutional protections, known as Lybarger or Garrity rights, which prevent forced statements from being used against them in criminal prosecutions.

Do I have the right to see the final investigation report or notes about me?

Not necessarily. In California for example, under Labor Code 1198.5, you have the right to inspect your official personnel file (which, thanks to the 2026 SB 513 update, now explicitly includes your detailed education and training records). However, this law specifically exempts records relating to the investigation of a possible criminal offense.

Furthermore, general HR interview notes, witness statements, and reports drafted by outside legal counsel are often kept separate from your official personnel file and may be entirely shielded from your view under attorney-client privilege.

Can HR or my boss secretly record my interview?

In California, which is a strict “two-party consent” state under Penal Code 632, it is a crime for an employer, HR representative, or third-party investigator to secretly record your confidential conversation or interview. If they wish to record the audio of the meeting, they must explicitly ask for your consent beforehand.

What happens if I report harassment, but the investigation concludes there isn’t enough proof? Can I be fired for lying?

As long as your complaint was made in good faith, you cannot be fired. California’s Fair Employment and Housing Act (FEHA) and whistleblower laws heavily protect employees from retaliation. Even if the investigator cannot definitively prove your claims, it is illegal for your employer to terminate, demote, or otherwise punish you simply for coming forward.
