11.2 Negligent Hiring, Discrimination & Harassment Investigations

Negligent Hiring, Discrimination & Harassment Investigations

Core Practice Standard: Two of the busiest commercial markets for California investigators sit inside a single knowledge cluster. Employers hire investigators before the harm, to screen candidates against negligent-hiring exposure, and after it, to investigate harassment and discrimination complaints. Both are governed by law the examination expects you to know, and the second carries a licensing requirement candidates frequently miss.

Part 1 — Negligent Hiring, Retention & Supervision

The Theory

These are California common-law negligence theories, distinct from respondeat superior. Respondeat superior makes an employer vicariously liable for an employee's torts committed within the scope of employment, regardless of employer fault. Negligent hiring makes the employer directly liable for its own fault in placing an unfit person in a position that created a particular risk — and it reaches conduct outside the scope of employment, which is exactly why plaintiffs plead it.

The California elements, drawn from cases such as Doe v. Capital Cities (1996) 50 Cal.App.4th 1038 and Federico v. Superior Court (1997) 59 Cal.App.4th 1207:

1. The employer hired, retained, or supervised the employee;
2. The employee was unfit or incompetent for the duties;
3. The employer knew or should have known of the unfitness;
4. The unfitness created a particular risk to others; and
5. That unfitness was a substantial factor in causing the plaintiff's harm.

The doctrinal hinge is the particular risk element. Courts look for a connection between the specific defect and the specific harm. A driving record matters for a delivery role; a decades-old, unrelated conviction generally does not, and reliance on it may itself be unlawful.

The Screening Paradox

A background investigation reduces negligent-hiring exposure only if it looks at the right things. California constrains what an employer may consider:

The investigator's job is therefore to run a job-related investigation: verify identity, education, and employment history; check professional licences with the issuing regulator; run driving records where driving is a duty and a permissible use exists; and surface conviction information only at the stage and in the form the client may lawfully use it.

Report discipline: deliver facts and their sources, not a hire/no-hire recommendation. The decision is the employer's, and the individualised assessment is the employer's legal duty. An investigator who writes "not recommended for hire" has taken on a decision they cannot defend.

Part 2 — Harassment and Discrimination Investigations

The Licensing Rule Candidates Miss

An outside person who investigates workplace misconduct for a fee is investigating "the identity, habits, conduct, business, occupation, honesty, integrity, credibility, knowledge, trustworthiness... or character of any person" — squarely BPC § 7521(b). In California that work requires a BSIS private investigator licence, unless the person is a licensed attorney performing legal duties as an attorney under BPC § 7522(e). The BPC § 7522(a) proprietary exemption covers only a regular, salaried employee working exclusively for the one employer, so an in-house HR investigator is exempt while an outside HR consultant, coach, or "workplace culture firm" is not. Unlicensed outside workplace investigation is a misdemeanour under BPC § 7523(b), and a licensee who knowingly engages such a person commits the same offence.

The FEHA Framework

Section 12940(k) is why investigation quality is itself a legal exposure: an employer that responds to a complaint with a slow, partisan, or superficial investigation has failed to take reasonable preventive steps, independent of whether the underlying harassment is proven.

The Cotran Standard

Cotran v. Rollins Hudig Hall International, Inc. (1998) 17 Cal.4th 93 asked what an employer must show when it terminates for misconduct the employee denies. The Supreme Court held the question is not whether the misconduct actually occurred, but whether the employer had reasonable grounds for believing it did, following an appropriate investigation in which the employee was given an opportunity to respond. That gives the investigator a concrete target: the file must show a good-faith, adequate investigation, not a predetermined result.

Conducting the Investigation

+---------------------------------------------------------------------------+
|  1. SCOPE      Written charge: allegations, policies at issue, timeframe   |
|  2. PLAN       Witness list, document requests, interim measures advised   |
|  3. INTERVIEW  Complainant -> respondent -> witnesses -> follow-up         |
|  4. EVIDENCE   Emails, messages, schedules, access logs, prior complaints  |
|  5. ANALYSE    Credibility factors; policy applied to found facts          |
|  6. REPORT     Findings of fact and policy conclusions; no legal opinions  |
+---------------------------------------------------------------------------+

Practical rules that recur on the examination:

• Impartiality is the product. An investigator who is also the employer's regular defence adviser has a conflict that will be used to attack the report.
• Credibility is assessed on stated factors — plausibility, motive to lie, corroboration, consistency over time, demeanour, and the existence of prior similar conduct — not on instinct.
• The standard is a preponderance, more likely than not, and the report should say so.
• No absolute confidentiality promises. The employer must be able to act on the findings, and a blanket confidentiality instruction to witnesses can itself be unlawful.
• Recording still requires all-party consent. Penal Code § 632 does not relax for workplace interviews; get recorded consent on the recording or take written statements instead.
• Do not opine on legal liability. Write "the conduct described violated Policy 4.2 on harassment," not "this constitutes unlawful harassment under FEHA." Legal conclusions belong to counsel and can waive privilege arguments.
• Retention. With a three-year FEHA filing window under Gov. Code § 12960(e) plus litigation time, investigation files must outlive the incident by years.

Case Example: The Consultant Who Was Not Licensed

Scenario: A 40-employee California company receives a harassment complaint and retains an outside "HR consulting group" — no BSIS licence, no attorney — for $12,000 to investigate. The consultant interviews eleven people, records the interviews with one-party consent, and delivers a report concluding that "the respondent's conduct constitutes unlawful harassment."

Three failures. The consultant engaged in the business of private investigator without a licence, a misdemeanour under BPC § 7523(b) with a $5,000 fine and/or a year in county jail, and neither the § 7522(a) proprietary exemption nor the § 7522(e) attorney exemption applies to a fee-charging outside consultant. Recording confidential workplace interviews without the consent of all parties violates Penal Code § 632, exposes the consultant to statutory damages of $5,000 per violation under Penal Code § 637.2, and renders the recordings inadmissible under § 632(d). And stating a legal conclusion rather than findings of fact hands opposing counsel an argument that the investigation was outcome-driven, undermining the employer's Cotran defence and its Gov. Code § 12940(k) preventive-steps position.
