Distinct Treatment of Religious Belief and Religious Practice Under Title VII

Introduction

This case arises from the 2025 decision of the United States Court of Appeals for the Fifth Circuit in Charlene Carter v. Southwest Airlines Company. Flight attendant Charlene Carter, a pro-life Christian and non-member objector to the Transport Workers Union Local 556, sent graphic anti-abortion images and videos to her union’s president and posted them publicly on social media. Southwest investigated, found she violated three neutral workplace policies (Social Media, Harassment, and Workplace Bullying), and fired her. An arbitrator sustained the termination. Carter then sued Southwest and the Union under Title VII of the Civil Rights Act of 1964 and the Railway Labor Act (“RLA”), claiming her firing discriminated against her religious beliefs and practices and that the Union unlawfully interfered with her rights. A jury sided with Carter, and the district court entered broad injunctive relief and held Southwest in contempt for its post-verdict notice to employees.

Summary of the Judgment

The Fifth Circuit reversed the denial of Southwest’s motion for judgment as a matter of law on Carter’s belief-based Title VII claim and her RLA retaliation claim, and remanded with instructions to enter judgment for Southwest on those claims.
It affirmed the judgment against Southwest on Carter’s practice-based Title VII claims.
It affirmed dismissal of Carter’s RLA interference claim against Southwest.
It affirmed all claims against the Union, including Title VII and RLA duties.
It vacated the district court’s broad permanent injunction and remanded for more precise relief.
It vacated the contempt order against Southwest as punitive and beyond the court’s civil‐contempt authority.

Title VII Framework: Trans World Airlines, Inc. v. Hardison (de minimis hardship test), Weber v. Roadway Express (more-than-de minimis cost), and Groff v. DeJoy (2023 Supreme Court clarification requiring “substantial increased costs” and excluding co-worker hostility as undue hardship).
Religious Accommodation Cases: Hebrew v. Texas Department of Criminal Justice (separate analysis for practice vs. discrimination), Abercrombie & Fitch Co. v. Equal Employment Opportunity Commission (motivating factor test).
RLA Jurisdiction and Remedies: Hawaiian Airlines v. Norris (major vs. minor disputes), Consolidated Rail Corp. v. Railway Labor Executives Association (limited judicial role), Steele v. Louisville & Nashville R. Co. and Vaca v. Sipes (implied union duty of fair representation).
Employers’ and Unions’ Duties: Brotherhood of Locomotive Engineers v. Union Pacific R.R. Co. (anti-union animus requirement for RLA claims), Roscello v. Southwest Airlines Co. (pre-certification interference with organizing).

2. Legal Reasoning

A central feature of the Fifth Circuit’s opinion is the text-driven distinction between Title VII claims based on a plaintiff’s sincerely held religious beliefs (the “belief-based” claim) and those based on the employee’s religious observances or practices (the “practice-based” claim). Under 42 U.S.C. § 2000e(j), “religion” includes “all aspects of religious observance and practice, as well as belief, unless an employer demonstrates that he is unable to reasonably accommodate” that observance or practice without undue hardship. The Groff decision clarified that Title VII’s “undue hardship” defense is a demanding “substantial increased costs” test, not the lenient Hardison “more than de minimis cost” rule.

The court held:

Belief-based claims cannot invoke the undue hardship defense; they require proof of intentional religious discrimination.
Practice-based claims and failure-to-accommodate claims share the undue hardship defense under the higher Groff standard.
Carter’s belief-based claim failed for lack of direct or sufficient circumstantial evidence that Southwest’s decision was motivated by animus toward her pro-life faith.
Carter’s practice-based claims survived because Southwest failed to show under the governing (and at-trial) “more than de minimis cost” standard that accommodating her social-media conduct—despite its psychological impact on co-workers—imposed an undue hardship.
The court refused a new trial under the post-trial Groff standard because Southwest had ample chance at trial to marshal evidence of substantial business costs but did not do so.

3. Impact on Future Cases

This decision will guide lower courts and litigants in the Fifth Circuit on religious-discrimination claims:

Separate Track for Belief vs. Practice: Parties must frame Title VII claims distinctly as belief-based discrimination (no undue hardship defense) or practice-based claims (subject to the stringent Groff undue hardship test).
Undue Hardship Standard: Groff is binding; employers must show “substantial increased costs” and cannot rely on mere co-worker hostility or minimal disruption.
RLA Claims Limited: Post-certification retaliation or interference claims require proof of anti-union animus or a breakdown of grievance procedures; employees cannot sue in federal court for general employer retaliation.
Injunctive Relief and Contempt: Courts must craft injunctions with precise, Rule 65(d) compliance, narrowly tailored to the prevailing party’s injury, and limit civil contempt sanctions to coercive or compensatory measures—not punitive training orders.

Complex Concepts Simplified

“Belief-Based” vs. “Practice-Based” Claims – Belief-based: discrimination because of faith tenets (no undue hardship defense). Practice-based: discrimination because of conduct in furtherance of faith (subject to undue hardship defense).
Undue Hardship – Under Groff, an employer must demonstrate that granting a religious accommodation would result in substantial additional costs relative to its business operations—not merely a minor inconvenience to the employer or co-workers.
Direct vs. Indirect Evidence – Direct evidence proves discriminatory motive outright (e.g., “You’re too religious, so we’re firing you”). Indirect (circumstantial) evidence requires the McDonnell Douglas framework: prima facie case, legitimate nondiscriminatory reason, and proof that the reason was pretext.
Major vs. Minor Disputes (RLA) – “Major” disputes involve collective bargaining negotiations; federal courts have original jurisdiction. “Minor” disputes arise under an existing agreement’s terms and generally go to arbitration.
Duty of Fair Representation – Unions owe all employees a duty to represent them “without hostility, discrimination, or arbitrary conduct.” Breaches give rise to a federal cause of action even in arbitration contexts.
Judgment Notwithstanding the Verdict (JNOV) – A party can request the court to overturn a jury verdict when no reasonable jury could have found for the non-moving party under the law.

Conclusion

The Fifth Circuit’s decision in Charlene Carter v. Southwest Airlines establishes important precedents:

Title VII claims must distinguish between religious belief and religious practice, with only practice-based claims subject to an undue hardship defense.
The Supreme Court’s Groff standard is controlling: employers must show substantial business costs to deny accommodations.
RLA suits in federal court are limited to anti-union animus or breakdowns in the dispute-resolution process; general retaliation or interference claims will be dismissed.
Injunctions must comply strictly with Rule 65(d) and be tailored to the litigant’s specific injury; civil contempt sanctions must remain coercive or compensatory, not punitive.

This ruling sharpens the boundaries of religious discrimination law, reinforces the separation of belief and practice under Title VII, and reminds litigants and courts to respect the carefully calibrated roles of arbitration and judicial relief in airline and labor disputes.
