When an employee complains: how to handle workplace investigations.

The duty is triggered when an employer has notice — actual or constructive — of conduct that may violate the law. Under Title VII, the ADA, the ADEA, and the Texas Commission on Human Rights Act (Chapter 21 of the Texas Labor Code), failure to investigate and take prompt remedial action when on notice can itself be the basis for liability. The Faragher-Ellerth defense from the 1998 Supreme Court decisions (Burlington Industries v. Ellerth and Faragher v. City of Boca Raton) permits an employer to avoid vicarious liability for supervisor harassment by showing it exercised reasonable care to prevent and promptly correct harassing behavior, and that the employee unreasonably failed to take advantage of preventive opportunities. Both prongs are required. A documented, prompt, and effective investigation is the principal mechanism for establishing the first prong. The threshold for triggering the duty is notice — the complaint does not need to be formal, written, or invoke specific legal terms.

The investigator must be impartial, qualified, and structurally appropriate to the matter. Three principles govern selection. The investigator cannot have a conflict — the supervisor accused of misconduct cannot investigate, and a manager who reports to the subject of the complaint should not lead. The investigator must have experience and training to conduct a competent investigation. The investigator must produce a documented record that will hold up if examined in litigation. For straightforward matters with lower-level employees, internal HR investigators are typically appropriate. For matters involving senior leadership, allegations of significant exposure, or facts that may invoke privilege considerations, outside counsel investigation is the better structure. Choosing the wrong investigator is one of the most common mistakes Texas employers make.

Privilege protection depends on how the investigation is structured at the outset. An investigation conducted by counsel for the purpose of providing legal advice can be protected by attorney-client privilege and the work-product doctrine. An investigation conducted by HR for the purpose of business decision-making generally is not. The structural choice is made at the moment the investigation begins and is largely irreversible — privilege established later does not retroactively protect work product created earlier. For routine HR complaints involving contained facts and limited litigation risk, an HR investigation is typically appropriate, and the resulting documentation is admissible — consistent with demonstrating prompt and effective response. For matters with meaningful litigation exposure, counsel-led investigation under the privilege architecture is the better choice. Privilege is a structural decision, not a label applied to documents after the fact.

Most workplace investigations should complete within 30 days from the date of the complaint, though appropriate timeline varies based on complexity. The EEOC has not specified a fixed timeline, but federal courts and EEOC enforcement consistently treat investigations dragging past 30 to 60 days as raising questions about whether the response was prompt for Faragher-Ellerth purposes. Investigations completing in fewer than seven days for serious allegations may suggest insufficient thoroughness; investigations taking 90+ days without justification often suggest a lack of urgency. Appropriate cadence: receipt and triage in days 1–3, investigation work in days 3–21, conclusion and findings in days 21–30, remediation beginning at day 30. Where an investigation legitimately requires more time, the timeline should be documented with a clear rationale.

Not absolute confidentiality, and attempting to promise it creates legal exposure. The investigation will require some information sharing with witnesses, the subject of the complaint, and others involved. The accurate communication: the employer will maintain confidentiality to the extent reasonably possible consistent with conducting a thorough investigation and complying with legal obligations. The NLRB has held that blanket confidentiality requirements during workplace investigations can violate Section 7 of the National Labor Relations Act, which protects employees' right to discuss workplace conditions including matters under investigation. Confidentiality directives must be limited and justified. The proper framing: the report will be handled with appropriate discretion, the investigation will follow established procedures, the matter will not be discussed beyond those involved in the investigation or in implementing any resulting action, and the employer prohibits retaliation. The promise of total secrecy does not describe what can be delivered.

No. The subject of the complaint must be given an opportunity to respond as part of any investigation that will produce findings or result in disciplinary action. The reasons are legal and practical. Legally, the absence of an opportunity to respond raises significant fairness questions that become focal points if the matter is later litigated. Practically, an investigation that does not include the subject's response cannot reach a credible factual conclusion — and process that reaches conclusions without hearing from the accused does not support the Faragher-Ellerth defense. The subject's interview is typically scheduled toward the end of the witness phase, after other witnesses and documents have been reviewed, so the subject can be presented with specific allegations and given the opportunity to address them factually. Limited circumstances may justify deferring notification — credible threat of evidence destruction, witness intimidation risks, active misconduct continuing — but those circumstances are exceptions, and the rationale should be documented contemporaneously.

Retaliation is adverse action taken against an employee because they engaged in protected activity — filing a complaint, participating in an investigation, or opposing what they reasonably believed unlawful conduct. Title VII, the TCHRA, and other federal and state laws prohibit it. Retaliation is one of the most common claim outcomes — even where the underlying complaint does not result in liability, retaliation against the complainant after the complaint frequently does. Adverse actions include obvious matters like termination, demotion, and pay reduction, but also less obvious actions like schedule changes, exclusion from meetings, negative performance reviews, increased scrutiny. The standard for adverse action is whether the action would dissuade a reasonable employee from engaging in protected activity — a lower threshold than other adverse-action analyses. Prevention requires three structural protections: the complainant's manager should be made aware of the prohibition; employment decisions affecting the complainant during and after the investigation should be reviewed before implementation; the situation should be monitored for at least 6–12 months after the investigation concludes.

Outside counsel is appropriate when one or more of the following is present. The subject of the complaint is senior leadership — CEO, executive, or other senior officer where impartial internal investigation is structurally difficult. The matter involves allegations of significant potential damages or systemic conduct — class allegations, multiple complainants, pattern allegations. The matter has regulatory implications. Internal investigative resources are inadequate to the matter. The matter is one the employer reasonably anticipates will result in litigation, where privilege protection of investigation work product becomes meaningfully valuable. The decision is rarely about cost — outside counsel investigation is more expensive than internal in the moment, but consistently less expensive than the alternative when the investigation becomes a focal point of subsequent litigation or regulatory action.
