# PIR-2026-0008 - Mobley v. Workday: AI screening vendor held potentially liable as the employer's "agent"

- `id`: PIR-2026-0008
- `title`: Court rules Workday's AI applicant-screening platform can be liable as an "agent" of client employers; ADEA collective conditionally certified
- `date_occurred`: 2020s (Mobley alleges rejection from 100+ jobs via Workday-powered portals; covered period spans years)
- `date_detected`: unknown (pattern surfaced through the plaintiff's own application history)
- `date_disclosed`: 2023-02 (complaint filed, N.D. Cal., 3:23-cv-00770); agent-theory ruling 2024-07-12; ADEA collective conditionally certified 2025-05-16
- `status`: disputed (discrimination alleged, not adjudicated; doctrinal rulings are on the record)

### The agent
- `agent_description`: Workday's AI-based applicant screening/recommendation platform, used across thousands of employers to score and reject candidates at scale, often with no meaningful human review of individual rejections.
- `operator_type`: enterprise (vendor operating on behalf of thousands of client employers)
- `autonomy_level`: autonomous-within-policy (alleged: algorithmic rejection without meaningful human review; some rejections within minutes, including overnight)
- `model_stack`: unknown (proprietary; contested in discovery)
- `harness`: Workday recruiting/HCM platform embedded in client employers' hiring portals
- `failure_locus`: tool-mcp (vendor platform: the alleged defect sits in a vendor tool performing a delegated function for many operators - the failure-locus pattern the v0.1 amendment was created for)

### Authority
- `authority_scope`: decision authority over hiring outcomes at fleet scale; data access (applicant PII across thousands of employers)
- `funds_at_risk_usd`: unknown (no damages adjudicated; potentially one of the largest employment collectives ever)
- `blast_radius`: fleet/systemic (one vendor's screening layer across thousands of employers; Workday's own filings state 1.1 billion applications were rejected through its tools in the covered period)

### The failure
- `root_cause`: policy-violation - primary: alleged disparate impact by age/race/disability under ADEA/Title VII/ADA. Contributing: unknown (whether defect is model, configuration, or client-set criteria is the litigation's open question)
- `mechanism`: Derek Mobley alleged rejection from 100+ positions through Workday-powered portals, sometimes within minutes of applying, attributing it to algorithmic bias. Judge Rita Lin (2024-07-12) denied dismissal on the theory that Workday acts as an "agent" of client employers when its tools perform the delegated function of screening and rejecting candidates - mapping agency law onto automated systems. On 2025-05-16 the court conditionally certified an ADEA collective; notice goes to a pool potentially including hundreds of millions of applicants.
- `adversary_present`: no
- `exploitation_status`: in-wild-malfunction (production screening of real applicants; no attacker; harm alleged, not adjudicated - reclassified from in-wild-exploited, which implies an adversary)

### Impact
- `severity`: degraded (no adjudicated loss; systemic exposure documented via certification)
- `direct_loss_usd`: unknown (no judgment)
- `indirect_loss_usd`: unknown
- `downtime`: n/a
- `data_exposure`: none

### Detection and recovery
- `detected_by`: third-party (rejected applicant inferring the pattern from his own outcomes)
- `time_to_detect`: years
- `time_to_recover`: ongoing (litigation active as of Aug 2026)
- `remediation`: none on public record
- `structural_fix`: none disclosed
- `controls_that_worked`: none identified - no internal control surfaced the alleged pattern; detection came from an external victim

### Legal
- `liability_holder`: contested - the live doctrinal question: Workday (vendor) as "agent" of client employers, i.e. vendor liability without the employer in the suit
- `precedent_set`: 2024-07-12 agent-theory ruling (AI vendors performing delegated hiring functions can be directly liable) + 2025-05-16 conditional ADEA certification at unprecedented scale
- `sealed_material`: unknown

### Evidence
- `telemetry_grade`: operator-logs (vendor-held screening records, contested in discovery)

  - `independence`: court clearinghouse + multiple independent law-firm analyses - strong on rulings.
- `aiid_incident_id`: 489 (https://incidentdatabase.ai/cite/489/) - cross-reference; primaries verified independently
- `confidence`: high on the rulings and the 1.1B-applications figure (from Workday's own filings as reported); low-medium on ultimate harm - discrimination is alleged, not proven.

### Verification notes
Ruling dates (2024-07-12, 2025-05-16), judge, and the 1.1 billion rejected-applications figure verified against court-record trackers and multiple independent legal analyses; all match intake. Blast_radius set to the v0.1 `fleet/systemic` tier: one vendor layer, thousands of downstream employers. Recorded under the v0.1 legal block.

### Corrections

- 2026-08-19: Added `aiid_incident_id` cross-reference (AIID 489), matched against the AIID weekly database export (2026-08-17). A cross-reference, not a re-verification; no claim changed.
