A human resources expert decides whether an employer's people practices met professional HR standards and its own written policy: how it hired, documented, disciplined, investigated and ended employment. The value is in practice, not law. This page covers HR process across employment disputes. Whether a practice was discriminatory, whether harassment occurred and whether wages were owed are questions for the claim itself and for the workplace discrimination, sexual harassment and wage and hour pages. Psychological harm belongs to a clinician, and lost earnings belong to a vocational or economic expert.
Rule 704 allows an opinion that embraces an ultimate issue, but the advisory committee note says other rules guard against opinions that "would merely tell the jury what result to reach" and those phrased in inadequately explored legal criteria 1. So a useful HR report does not say the employer retaliated. It says what a competent HR function does when a complaint arrives, what this employer did, how the two differ, and what the difference likely meant for the outcome.
The expert should name the source of each standard. HR has no licensing board and no single binding code. Standards come from the employer's own handbook and training, published professional guidance, and the expert's documented experience. An opinion resting only on "that's not how it's done" invites a challenge.
Two recent Supreme Court decisions widened the set of decisions that get examined.
In either setting the core analysis is consistency. The expert compares how the plaintiff and similarly situated employees were treated under the same policy, by the same decision maker, in the same period.
The file usually includes the handbook and its revision history, job descriptions, performance reviews and improvement plans, discipline logs, complaint intake records, investigation notes, comparator files, HR system audit data and termination paperwork. Timing is often the story: a first negative review dated after a complaint means something different from a pattern documented long before it.
Federal rules set a floor for retention. Under 29 CFR 1602.14, personnel records must generally be kept for one year from the making of the record or the personnel action, and the records of an involuntarily terminated employee for one year from termination 4. Once a charge is filed, the employer must preserve all relevant personnel records until final disposition 4. Gaps in that record are part of the expert's assessment, and other laws can impose longer periods.
HR reports often lean on agency guidance, and that footing moved in 2026. The EEOC voted 2-1 in January 2026 to rescind its 2024 Enforcement Guidance on Harassment in the Workplace 5. In June 2026, the Justice Department's Office of Legal Counsel concluded that EEOC interpretations, including the Uniform Guidelines on Employee Selection Procedures, embrace an unconstitutional reading of Title VII's disparate impact provisions 6. That opinion also describes the Guidelines as still in effect at that time 6, and an Office of Legal Counsel opinion is not a court judgment. For a selection procedure case, the expert must separate what the regulation says, what the agencies are doing, and what the forum's courts require on the date of the report. HR practice in place when the decision was made should be judged by the guidance then available.
Look for senior practitioners who ran the function at an employer of similar size and sector: chief HR officers, HR directors and employee relations leads who wrote policy, conducted investigations and defended decisions. Two certifications are widely held. SHRM-SCP is for individuals with at least 3 years of strategic-level HR work 7. HRCI's SPHR requires at least four years of professional-level HR experience with a master's degree, five with a bachelor's, or seven without a degree 8. Certification shows knowledge, but investigation and discipline experience in the same setting is what makes the opinion hold up.
Under 29 CFR 1602.14, once a charge of discrimination is filed the employer must preserve all personnel records relevant to the charge until final disposition.

FAQ
Look for a senior practitioner who ran HR at a comparable employer and personally handled complaints, investigations and terminations. SHRM-SCP and SPHR are widely held certifications, but HR has no license or board. Direct experience in the same setting usually matters more than the credential.
An opinion may embrace an ultimate issue under Rule 704, but opinions that merely tell the jury what result to reach are subject to exclusion. A strong HR report describes the professional standard, what the employer did and how they differ. It leaves the legal conclusion to the jury.
Typically the handbook and its revisions, job descriptions, performance reviews, discipline logs, complaint and investigation records, comparator files, and HR system data. The expert looks at consistency across employees and at the timing of documents relative to a complaint or decision.
Under 29 CFR 1602.14, generally one year from the making of the record or the personnel action, and one year from termination for an involuntarily terminated employee. When a charge is filed, relevant records must be preserved until final disposition. Other laws may set longer periods.
Check each one. The EEOC voted in January 2026 to rescind its 2024 harassment guidance, and a June 2026 Office of Legal Counsel opinion criticized its disparate impact interpretations, including the Uniform Guidelines. An expert should state what was in effect at the time of the conduct and at the date of the report.
In general, human resources expert fees are determined by the expert themselves, based on a variety of criteria. Among those criteria are professional experience, forensic experience, industry certifications, investigation experience, and publications. Vident does have some influence over expert fees by comparing experts within a specialty, but ultimately it is a personal decision by the expert.
