UNITED STATES DISTRICT COURT WESTERN DISTRICT OF TEXAS WACO DIVISION

JENNA HORNBUCKLE, § § Plaintiff, § § v. § CIVIL NO. 6:24-CV-00616-ADA § VISTRA CORP. and LUMINANT § GENERATION COMPANY LLC, § § Defendants. §

ORDER

Before the Court is Defendants’ Motion for Summary Judgment. Dkt. No. 22. The Court has reviewed the Motion, Plaintiff’s Response (Dkt. No. 24), Defendants’ Reply (Dkt. No. 25), the applicable laws, and the record of this case. The Court finds that Defendants’ Motion should be granted.

I. BACKGROUND Plaintiff Jenna Hornbuckle sued Vistra Corp. and Luminant Generation Company LLC (collectively, “Defendants”) alleging discrimination and retaliation under the Americans with Disabilities Act of 1990 (“ADA”). Dkt. No. 1, Compl. Plaintiff was employed by Defendants from June 4, 2012, until she was terminated on August 19, 2023. Id. ¶ 4.1. Plaintiff was an Operations Procedure Writer at the Comanche Peak Nuclear Power Plant and as part of her job she was expected to be on-site at least three days a week and travel on foot as needed to evaluate areas of the nuclear plant or talk to colleagues. Id.; Dkt. No. 22-2, Ogletree Decl. ¶ 6. Plaintiff began experiencing health issues in December of 2022 which she attributes to Muckle Wells Syndrome, and she requested and went out on short-term disability. Dkt. No. 1, Compl. ¶ 4.2. On April 26, 2023, Plaintiff asked her supervisor if she could come back to work and temporarily work from home and her supervisor informed her that she could not work from home because of the company’s policy that she be on-site three days a week. Id. ¶ 4.3. Plaintiff underwent emergency surgery on May 24, 2023, and ultimately experienced an unfortunate series of complications and further health problems leading up to the time when her short-term disability expired on June 9, 2023. Id. ¶ 4.4.

Following the end of her short-term disability, Plaintiff applied for long-term disability benefits and concurrently engaged with Defendants in a request for workplace accommodations. See id. ¶¶ 4.5-4.6; Dkt. No. 22-1, Hornbuckle Dep. 166:7-15. Plaintiff ultimately was approved for long-term disability benefits. See Dkt. No. 22-1, Hornbuckle Dep. 166:16-17. Despite her concurrent application for long-term disability benefits, Defendants engaged with Plaintiff in an effort to determine whether there could be reasonable workplace accommodations. Dkt. No. 1, Compl. ¶¶ 4.5-4.7. Plaintiff’s complaint alleges that Defendants’ refusal to provide an accommodation lacked any basis and was disability discrimination and retaliation. Id. ¶ 4.10. Defendants, however, explain that in the process of completing

accommodation paperwork, the paperwork Plaintiff submitted indicated that she was not released to return to work and could not perform any work for at least six months. Dkt. No. 22-2, Ogletree Decl. ¶¶ 12-13. Defendants also explained that Plaintiff’s medical provider, Leslie Ross, P.N.P., spoke with Jennifer Ogletree, Director of Employee Relations for Defendants that was handling Plaintiff’s accommodation request. See id. ¶¶ 3, 16. Defendants explain that Ms. Ross informed Ms. Ogletree that Plaintiff would likely only be able to work for four hours spread throughout the day and that she would be receiving palliative care at home during which times Plaintiff could not work at all. Id. ¶ 16. Ms. Ross confirmed that Plaintiff could not perform the essential functions of her job and that these conditions were expected to last for at least six months. Id. ¶¶ 16-17. Plaintiff similarly confirmed that her health problems result in her having “episodes” a couple times a week, lasting a couple of hours or all day, wherein she has blurred, double vision that impacts her ability to read and has no treatment. See Dkt. No. 22-1, Hornbuckle Dep. 71:3-72:6. Ultimately, after Plaintiff was approved for long-term disability benefits, her employment was terminated on August 19, 2023. Dkt. No. 1, Compl. ¶ 4.8. Defendants told Plaintiff the reason

for her termination was that she could not perform the essential duties of her job. Id. II. LEGAL STANDARD Summary judgment is proper where there are no genuine issues of material fact, and the moving party is entitled to judgment as a matter of law. FED. R. CIV. P. 56. If the record, taken as a whole, could not lead a rational fact finder to find for the non-moving party, then there is no genuine issue for trial. See Ricci v. DeStefano, 557 U.S. 557, 586 (2009). In determining whether a genuine issue of material fact exists, the court must draw all inferences from the evidence in the light most favorable to the non-movant and resolve all reasonable doubts in that party’s favor. Harville v. City of Houston, Mississippi, 945 F.3d 870, 874 (5th Cir. 2019); Chaplin v.

NationsCredit Corp., 307 F.3d 368, 371–372 (5th Cir. 2002). Where the non-moving party will bear the burden of proof at trial on a dispositive issue, that party also bears the burden of production to demonstrate that there is a genuine issue for trial. See FED. R. CIV. P. 56; see also Celotex Corp. v. Catrett, 477 U.S. 317, 324 (1986). III. ANALYSIS

A. Disability Discrimination Claims The ADA prohibits employers from discriminating against an employee on the basis of a disability as defined by the Act. Rodriguez v. Eli Lilly & Co., 820 F.3d 759, 764 (5th Cir. 2016) (citing 42 U.S.C. § 12112 (2009)). “In a discriminatory-termination action under the ADA, the employee may either present direct evidence that she was discriminated against because of her disability or alternatively proceed under the burden-shifting analysis first articulated in McDonnell Douglas Corp. v. Green, 411 U.S. 792, 93 S.Ct. 1817, 36 L.Ed.2d 668 (1973).” Id. (quoting EEOC v. LHC Grp., Inc., 773 F.3d 688, 694 (5th Cir. 2014)). Under the McDonnel-Douglas burden shifting test for establishing a disability

discrimination case, the plaintiff must prove (1) that she had a disability, (2) that she was qualified for the job, and (3) that she was subject to an adverse employment decision on account of her disability. See id. (citing LHC Grp., 773 F.3d at 697). If the plaintiff meets that burden, the defendant can rebut the presumption of discrimination by articulating legitimate business reasons for the adverse action. See id. (citing LHC Grp., 773 F.3d at 701). Then, if the defendant provides a legitimate reason, the plaintiff must offer evidence to show that the reason was a pretext for discrimination. Id. (citing LHC Grp., 773 F.3d at 702). The parties do not dispute that Plaintiff suffered from a disability for the purposes of establishing the first required element. Here, the primary issue raised by Defendants is that Plaintiff
