Workplace Investigations: What Employees Should Know
You filed a complaint about harassment, discrimination, or illegal conduct. The employer says it will investigate. What happens next — and what should you expect, watch for, and do — is something most employees are not prepared for.
The decision to file an internal complaint is difficult enough. What follows — the employer’s investigation — introduces a new set of uncertainties. Who will investigate? What will they ask? Will the complaint be taken seriously or handled as a formality? Will there be retaliation despite the employer’s assurances? What rights does the employee have during the process?
These questions are practical, not theoretical, and the answers affect both the employee’s experience and the strength of any subsequent legal claim. An employee who understands the investigation process is better positioned to participate effectively, to identify when the process is going wrong, and to preserve their options.
The employer’s obligation
When an employer receives a complaint of harassment, discrimination, or other unlawful conduct, FEHA requires it to conduct a prompt, thorough, and impartial investigation. Government Code section 12940, subdivision (k). This obligation is triggered by the complaint itself — the employer does not have discretion to ignore it, to defer it indefinitely, or to decline to investigate because it considers the complaint unlikely to be substantiated.
The investigation must be conducted by a person who is neutral — someone without a stake in the outcome and without a relationship to the accused or the complainant that would compromise objectivity. In smaller organizations, this may be a senior HR professional. In larger ones, it may be a dedicated investigator or an outside firm retained for the purpose. The choice of investigator matters: an investigation conducted by the accused person’s close colleague, or by someone with a history of bias, is not impartial, and the results will be scrutinized accordingly.
What to expect
The investigation typically follows a structured process, though the specifics vary by employer.
The intake interview. The investigator will interview the complainant — usually early in the process — to understand the allegations in detail. The employee should be prepared to describe what happened, when it happened, who was involved, who witnessed it, and what documentation exists. Specificity matters: dates, locations, exact words used, the sequence of events. The more precise the employee can be, the more effectively the investigator can corroborate or investigate the allegations.
Witness interviews. The investigator will interview witnesses identified by the complainant, witnesses identified by the accused, and potentially other individuals who may have relevant knowledge. The employee should provide the investigator with the names of anyone who witnessed the conduct or who has relevant information.
Document review. The investigator may review emails, text messages, performance records, HR files, security footage, and other documents. If the employee has documentary evidence — emails reflecting the complained-of conduct, text messages, written communications — they should provide copies to the investigator.
The accused’s response. The person accused of the conduct will be given an opportunity to respond. This is a fundamental requirement of a fair investigation. The complainant should expect that the accused will deny or minimize the allegations, and that the investigator will need to assess credibility.
Findings and conclusion. The investigator will reach a conclusion: whether the alleged conduct occurred, and whether it violated the employer’s policies or the law. The complainant is typically informed of the outcome — though not necessarily of the specific disciplinary action taken against the accused, which may be confidential.
What to watch for
Not all investigations are conducted in good faith. An employee should be alert to signs that the process is being managed to reach a predetermined conclusion.
The investigation that takes too long. A prompt investigation means weeks, not months. An investigation that drags on for an extended period — without communication, without updates, without apparent progress — may not be a genuine investigation. Delay can serve the employer’s interests by discouraging the complainant, allowing memories to fade, and creating an impression that the complaint was not serious enough to warrant urgent attention.
The investigation that does not contact key witnesses. If the employee identified specific witnesses who observed the conduct, and the investigator did not interview them, the investigation may not be thorough. An investigator who avoids witnesses likely to corroborate the complaint is not conducting a neutral investigation.
The investigator who appears to be advocating for the accused. A neutral investigator asks open-ended questions and evaluates the evidence. An investigator who challenges the complainant’s account aggressively, suggests alternative explanations for the conduct, or frames questions in ways that minimize the allegations is not acting as a neutral fact-finder.
The conclusion that ignores evidence. If the investigation concludes that the conduct did not occur, or that it did not violate policy, despite evidence to the contrary — corroborating witnesses, documentary evidence, a pattern of similar complaints — the conclusion may reflect the employer’s preferred outcome rather than the evidence.
Retaliation during or after the investigation. The most important thing to watch for is any change in how the employee is treated following the complaint. A shift in assignments, a negative performance review, exclusion from meetings, a change in the supervisor’s demeanor, increased scrutiny — any of these, occurring in proximity to the complaint, may constitute retaliation. Retaliation is independently unlawful under FEHA, regardless of the outcome of the investigation.
The employee’s rights during the process
Several rights and practical considerations apply throughout the investigation.
Confidentiality. The employer will typically ask the complainant to keep the complaint and the investigation confidential. The employee should understand the scope of this request. An employer may ask employees not to discuss the investigation with coworkers to protect the integrity of the process. An employer may not, however, use a confidentiality directive to prevent the employee from consulting with an attorney, filing a complaint with the CRD, or exercising any other legal right.
Freedom from retaliation. FEHA prohibits retaliation against an employee for filing a complaint, participating in an investigation, or exercising any right under the statute. Government Code section 12940, subdivision (h). This protection is absolute — it does not depend on the outcome of the investigation or the merits of the underlying complaint. An employer that retaliates against an employee for complaining about harassment has violated the law, even if the investigation concludes that no harassment occurred.
The right to consult with an attorney. An employee may consult with an attorney at any point during the investigation. The consultation is confidential and does not affect the investigation. An attorney can advise the employee on how to participate effectively, what to document, what rights are at stake, and whether the investigation appears to be conducted fairly.
No obligation to accept the outcome. The employer’s investigation is the employer’s process. Its conclusion is not binding on the employee. If the investigation concludes that no violation occurred, the employee retains the right to file a complaint with the CRD, to pursue legal action, and to challenge the adequacy of the investigation in court. An inadequate investigation — one that was not prompt, thorough, or impartial — can itself be evidence of the employer’s failure to meet its obligations under FEHA.
Documentation during the investigation
An employee who is participating in a workplace investigation should maintain their own records throughout the process.
Note the date the complaint was filed and the date the investigation began. Record the name and title of the investigator. After each interview, write down the questions that were asked and the answers given, as close to the time of the interview as possible. Note any communications from the employer about the status of the investigation. Document any changes in treatment — positive or negative — that occur after the complaint is filed.
These records serve two purposes. They preserve the employee’s account of the process in case it is later disputed. And they create a timeline that can be compared to the employer’s account if the adequacy of the investigation is ever challenged in litigation.
If you have filed an internal complaint and the employer is investigating, the investigation should be prompt, thorough, and impartial. If it is not — or if you experience retaliation during or after the process — those failures are themselves violations that the law addresses. Your role is to participate candidly, document carefully, and understand that the employer’s process does not define the limits of your options.
