Hospital Privilege Control Does Not Establish Joint Employment; Unnamed Employers Require EEOC-Charge Exhaustion

1. Introduction

These consolidated Fourth Circuit appeals arise from Covid-19 vaccination requirements imposed at Inova medical facilities. Plaintiffs Kelly M. Hoffman and Lorraine Biondi Austin—Certified Registered Nurse Anesthetists (CRNAs)—worked exclusively at Inova facilities but were formally employed by American Anesthesiology of Virginia, a subsidiary of North American Partners in Anesthesiology (NAPA). After Inova denied their exemption requests and suspended their clinical privileges when they refused vaccination, NAPA later terminated their employment.

The central legal issues were (1) whether Inova could be treated as Plaintiffs’ “employer” under Title VII, the ADA (Hoffman only), and the Virginia Human Rights Act (VHRA) under the Fourth Circuit’s joint-employment framework; and (2) whether Hoffman exhausted administrative remedies against NAPA when her EEOC charge named only Inova, even though she later sent a letter to the EEOC attempting to add NAPA.

2. Summary of the Opinion

The Fourth Circuit affirmed across the board. First, it held that Plaintiffs did not plausibly allege that Inova was their employer under the joint employment doctrine. Applying the nine-factor test from Butler v. Drive Automotive Industries of America, Inc., the court emphasized the “principal guidepost” of common-law control and found especially lacking: (i) Inova’s authority to hire or fire Plaintiffs; (ii) day-to-day supervision/discipline; and (iii) involvement in employment records (payroll, taxes, insurance).

Second, it held that Hoffman failed to exhaust administrative remedies against NAPA because her EEOC charge did not name NAPA, and her later private letter to the EEOC did not amend the charge or provide notice to NAPA. The court relied chiefly on Sloop v. Memorial Mission Hosp., Inc. and Balas v. Huntington Ingalls Indus., Inc..

3. Analysis

3.1. Precedents Cited

A. Pleading and motion-to-dismiss standards

• Bing v. Brivo Sys., LLC and Corder v. Antero Res. Corp. (quoting Rockville Cars, LLC v. City of Rockville): The court reiterated de novo review, acceptance of well-pleaded facts, and favorable inferences to the nonmovant—while still requiring plausibility.
• Ashcroft v. Iqbal: The opinion leaned heavily on Iqbal’s core distinction—legal conclusions and “naked assertions” do not suffice; facts must “nudge” claims from conceivable to plausible.
• Goines v. Valley Cmty. Servs. Bd.: The court approved considering a contract at the pleading stage because it was integral to the complaint and its authenticity was undisputed—important to defeating the asserted “Inova can fire me” narrative.

B. Joint employment and the “control” guidepost

• Butler v. Drive Automotive Industries of America, Inc.: This was the controlling framework. The court used Butler’s nine factors and highlighted that the first three factors (hire/fire authority; day-to-day supervision/discipline; furnishing equipment/place of work) are “most important,” while also reaffirming that no one factor is dispositive and factors may be adapted to industry context.
• Cilecek v. Inova Health Sys. Servs.: This healthcare-context precedent significantly shaped the analysis. The court used Cilecek to treat hospital control over medical services, and the furnishing of hospital space/equipment, as generally weak indicators of an employment relationship because hospitals must maintain oversight for patient safety regardless of whether providers are employees.
• Clackamas Gastroenterology Assocs., P.C. v. Wells (footnote): Cited for the general principle that the “common-law element of control” is the “principal guidepost” when interpreting employment status under the ADA—supporting use of the same control-centric approach beyond Title VII.
• Smith v. CSRA (footnote): Cited for applying the Butler factors to an ADA claim, reinforcing the district court’s and panel’s approach of using the same joint-employer analysis for Title VII and ADA in this circuit.
• Crump v. TCoombs & Assocs., LLC: Discussed and distinguished. The opinion explains that Crump involved extensive governmental screening, interviewing, supervision, and transfer authority—facts not alleged here—demonstrating the level of control necessary to plausibly plead joint employment in a medical setting.
• Sibley Memorial Hospital v. Wilson (raised at argument): The court rejected reliance on Sibley as misplaced due to materially different facts and because Sibley did not apply the Ninth-factor Butler analysis used in the Fourth Circuit.

C. Administrative exhaustion and scope of the charge

• Walton v. Harker: Used for the proposition that an EEOC charge defines the scope of subsequent litigation and generally limits judicial claims to what was presented administratively.
• Sydnor v. Fairfax Cnty.: Cited for the purposes of exhaustion—notice to the employer and giving the agency a first opportunity at conciliation.
• Sloop v. Memorial Mission Hosp., Inc.: Central to rejecting Hoffman’s “letter as amendment” theory. The court treated it as “objectively illogical” to construe a private letter as amending a formal charge when it does not provide notice to the employer.
• Cowgill v. First Data Techs., Inc.: Reinforced Sloop by rejecting attempts to expand a charge through communications with EEOC personnel outside the charge itself.
• Balas v. Huntington Ingalls Indus., Inc.: The opinion relied on Balas’s restriction that, in determining what claims were properly alleged, courts “may look only to the charge filed with that agency,” underscoring the formal-document boundary.
• Edelman v. Lynchburg College: Distinguished as largely irrelevant because it concerned relation-back/timeliness and agency delay, not adding a new respondent without notice.

D. Appellate waiver for underdeveloped arguments

• Short v. Hartman (quoting Grayson O Co. v. Agadir Int'l LLC): The court applied waiver principles to Hoffman's late, undeveloped footnote reference to an “updated Complaint Questionnaire.”
• Wahi v. Charleston Area Med. Ctr., Inc.: Reinforced that skeletal, footnote-only claims can be waived on appeal.

3.2. Legal Reasoning

A. Joint-employer plausibility under Butler (with healthcare-context adjustments)

The panel methodically applied Butler’s nine factors, repeatedly emphasizing that Plaintiffs’ pleadings did not supply concrete facts showing that Inova exercised the kind of employer-like control that would justify Title VII/ADA/VHRA liability.

• Authority to hire and fire (Factor 1): Plaintiffs alleged they were hired by entities that became part of NAPA; they alleged no Inova role in hiring. On firing, Hoffman relied on a contract clause: if a facility demanded removal, that could constitute “cause” for termination. The court, reading the contract under Goines v. Valley Cmty. Servs. Bd., held the discretion to terminate remained with American Anesthesiology/NAPA “in its sole discretion.” Inova’s suspension of privileges created a contractual predicate, not actual termination authority.
• Day-to-day supervision and discipline (Factor 2): Plaintiffs’ allegations were characterized as conclusory (“oversight,” “control”) without naming supervisors or describing chain-of-command facts—particularly notable because Virginia law requires CRNA supervision by a physician (a context in which supervision may be clinical rather than employment-based). The one anecdote about being offered time off and later “disciplined” by “other Inova staff” was treated as too isolated and too undeveloped to plausibly show day-to-day practical control.
• Equipment and place of work (Factor 3): Although Inova provided facilities and equipment, the court treated this as weak evidence in a hospital context, relying on Cilecek v. Inova Health Sys. Servs.—hospitals necessarily provide instruments and space even to non-employees with privileges.
• Employment records (Factor 4): Plaintiffs did not allege Inova handled payroll, taxes, benefits, or insurance. Inova’s possession of credentialing/licensure/vaccination records was treated as patient-safety/compliance related rather than employment-record control.
• Duration and exclusive assignment (Factors 5 and 8): Working exclusively at Inova for years was acknowledged but treated as limited in probative value without corresponding facts showing Inova’s employer-like control, particularly because NAPA had arrangements beyond Inova and Plaintiffs admitted NAPA was their employer.
• Training (Factor 6): Training on charting systems, equipment, harassment, privacy, and debriefing after adverse outcomes was treated as legally/operationally necessary for anyone practicing at the hospital. Plaintiffs did not allege Inova trained them in the core anesthetic function that distinguished them.
• Duties akin to regular employees (Factor 7): The court found Plaintiffs’ anesthetic duties were distinct and reserved to their contractor employer’s staff; ancillary patient-care tasks (IV placement, repositioning) occurred within their CRNA role and did not make their duties “akin” to Inova nurses generally.
• Intent to enter an employment relationship (Factor 9): Plaintiffs did not allege they intended employment with Inova; their pleadings acknowledged they were credentialed NAPA employees working in Inova facilities.

The opinion’s throughline is that, especially in healthcare, credentialing, privileges, clinical protocols, and hospital governance are often necessary conditions of patient care—not indicators of an employer-employee relationship. Without plausible allegations of hiring/firing authority, day-to-day supervision, and employment-record control, the joint-employer theory failed.

B. Exhaustion against an unnamed employer: the “formal charge” boundary

Hoffman’s EEOC charge named only Inova; the right-to-sue notices were likewise sent to Inova. Her later “Update and Amendment” letter naming NAPA did not result in an amended charge or notice to NAPA. The court held that treating such a letter as a constructive amendment would defeat exhaustion’s purposes—notice and conciliation—citing Sloop v. Memorial Mission Hosp., Inc., Cowgill v. First Data Techs., Inc., and Balas v. Huntington Ingalls Indus., Inc..

The court also rejected Hoffman’s VHRA exhaustion theory to the extent it relied on the same letter, and it found any alternative argument based on an “updated Complaint Questionnaire” waived as underdeveloped, invoking Short v. Hartman and Wahi v. Charleston Area Med. Ctr., Inc..

3.3. Impact

• Healthcare joint-employment pleadings will face a heightened “contextual plausibility” hurdle: The decision reinforces that allegations typical of hospital privilege regimes—credentialing, medication formulary controls, use of hospital equipment, mandatory compliance training—will often be treated as non-probative under Cilecek v. Inova Health Sys. Servs. unless paired with concrete facts showing employment-like control.
• Privilege suspension is not firing authority (without more): The opinion draws a firm line between a hospital’s decision to deny access/privileges and an employer’s decision to terminate—particularly where contracts vest termination discretion in the staffing/employing entity.
• Exhaustion remains document-centric and respondent-specific: The court underscores a formalist boundary: plaintiffs cannot rely on letters, portal uploads, or side communications to expand the respondent set absent an amended charge and notice. Practically, plaintiffs must ensure each intended defendant is named (or properly included under recognized exceptions not addressed here) and receives notice through the charge process.
• Procedural discipline on appeal: The waiver discussion signals that litigants should fully develop exhaustion records and arguments in opening briefing, not footnotes.

4. Complex Concepts Simplified

5. Conclusion

The Fourth Circuit’s decision cements two practical rules for employment-discrimination litigation in healthcare staffing contexts. First, hospitals’ ordinary privilege, safety, and compliance controls—without concrete allegations of employer-like authority over hiring/firing, daily supervision, and employment records—will not plausibly establish joint employment under Butler v. Drive Automotive Industries of America, Inc., especially given the contextual caution of Cilecek v. Inova Health Sys. Servs.. Second, plaintiffs must exhaust administrative remedies against each intended defendant by naming that entity in the EEOC charge (or otherwise properly amending the charge with notice); private letters or portal uploads that do not amend the charge and do not notify the employer are insufficient under Sloop v. Memorial Mission Hosp., Inc. and Balas v. Huntington Ingalls Indus., Inc..
