Opinion

UNITED STATES DISTRICT COURT WESTERN DISTRICT OF TEXAS SAN ANTONIO DIVISION

ZHENMEI LIU, § Plaintiff § § v. § Case No. SA-23-CA-01230-XR § KCI USA, INC., 3M COMPANY, § ACELITY HOLDINGS, INC., § Defendants §

ORDER GRANTING SUMMARY JUDGMENT On this date, the Court considered Defendants 3M Company, KCI USA, Inc., and Acelity, Inc.’s Motion for Summary Judgment (ECF No. 32) and the associated filings (ECF Nos. 37, 41– 42, 44). After careful consideration, the Motion for Summary Judgment (ECF No. 32) is GRANTED, and this case is DISMISSED. BACKGROUND1 Plaintiff Zhenmei Liu began working at KCI in October 2006, as a Senior Biostatistician. ECF No. 32-4 at 3. KCI manufactured medical devices, particularly related to wound care. Id. Liu worked with a team on the design, conduct, and analysis of clinical trials for KCI’s products. Id. In 2017, Liu began reporting to Senior Manager Yeni Nieves, who in turn reported to Senior Director (later, Vice President) of Global Clinical Affairs Jane Hart. Id. In June 2018, Liu

1 Because this case is at the summary judgment stage, the Court views “facts that are subject to genuine dispute . . . in the light most favorable to” the nonmovant. Taylor v. Riojas, 592 U.S. 7, 8 n.1 (2020). Both parties object to certain summary judgment evidence. Liu objects to the declaration of Jane Hart. See ECF No. 45–50. But her objections are essentially that the declaration is factually inaccurate. See id. A factual disagreement does not render summary judgment evidence incompetent. Defendants, for their part, provide about seventy-five pages of objections to Liu’s declaration and other exhibits. See ECF No. 44. The Court need not address these objections, because it grants the Motion regardless. 1 received a raise. ECF No. 32-4 at 23. At some point before receiving that raise, Liu was promoted to the position of Global Lead Statistician.2 I. Liu’s Employment Evaluations Employees at KCI, including Liu, were subject to quarterly and year-end performance

reviews. ECF No. 32-4 at 4; ECF No. 32-4 14–21, 26–50. In those reviews, both the manager and the employee provided comments on the employee’s performance related to specific objectives. See ECF No. 32-4 at 14–21, 26–50. For each objective, the employee and manager also each provided a “rating,” such as “Achieves Results Well Beyond Expectations,” “Consistently Achieves Results,” “Meets Some But Not All Expectations,” or “Does Not Meet Expectations.” See id. The year-end reviews included an overall numerical rating, corresponding to an overall qualitative rating like those for each objective. See ECF No. 32-4 at 14, 34. In Liu’s 2017 year-end performance review, Nieves gave Liu consistently high ratings. Liu’s overall numerical rating was 4.31, meaning she “Achieves Results Well Beyond Expectations.” ECF No. 32-4 at 14. The evaluation listed three objectives, and Liu received high

ratings on all of them. ECF No. 32-4 at 14–19. Throughout the rest of her time at KCI, Liu received similarly good evaluations and feedback on some objectives. See, e.g., ECF No. 32-4 at 27, 39, 44. And as late as April 2019, Liu received commendations separate from her formal evaluations for certain aspects of her work. See ECF No. 37-2 at 2, 139. But starting in 2018, Liu’s performance reviews became less consistently positive. See ECF No. 32-4 at 14–21, 26–50. In her third-quarter 2018 evaluation, for example, she received a

2 Defendants assert that Liu became Global Lead Statistician when she received the raise in June 2018. ECF No. 32-2 at 3. But in her deposition, Liu testified that she had that title before receiving the raise and, in fact, before Nieves began working at KCI. ECF No. 32-3 at 11. Liu’s 2017 performance review lists her job title as “Global Lead Statistician,” providing further evidence that she received the title before June 2018. ECF No. 32-4. 2 rating of “Meets Some But Not All Expectations” on her only completed objective. See ECF No. 32-4 at 30–32. And in her 2018 year-end evaluation, her overall numerical rating was 3.07, meaning she “Consistently Achieves Results.” ECF No. 32-4 at 34. Her objective-by-objective ratings were similarly less consistent than before. See ECF No. 32-4 at 34–41. And Liu’s own

“calculated rating” of her work decreased from 4.77 in 2017 to 3.79 in 2018. See ECF No. 32-4 at 14, 34. Liu’s 2019 evaluations followed a similar pattern. See ECF No. 34-2 at 43–50. In her final evaluation—for the second quarter of 2019—she had three objectives. See ECF No. 34-2 at 47– 50. On two, Nieves gave her a rating of “Meets Some But Not All Expectations.” See id. On the third, her rating was “Does Not Meet Expectations.” ECF No. 34-2 at 48. II. Performance Improvement Plan and Termination On August 28, 2019, about two months after Liu’s second-quarter 2019 evaluation, see ECF No. 32-4 at 47, Nieves provided Liu a “Performance Improvement Plan” (“PIP”). ECF No. 32-4 at 52–55. Therein, Nieves identified certain areas in which Liu was allegedly not meeting

expectations, along with descriptions and examples of the alleged performance deficiencies. See id. The PIP also included “expected goals” and established a sixty-day “improvement period.” See id. It specified that “KCI reserve[d] the right to terminate the [PIP] and terminate [Liu’s] employment at any time during/after the PIP.” ECF No. 32-4 at 55. On September 24, 2019, Nieves met with Liu again to review an updated version of the PIP. See ECF No. 32-4 at 57. The updated PIP indicated that Liu had demonstrated minimal or no improvement on each of the original PIP’s “expected goals.” See ECF No. 32-4 at 59–62. Liu did not want to sign the updated PIP because she did not think it was accurate. ECF No. 32-3 at 17. But Nieves told her that if she did not sign, she could not leave the office. Id. So Liu signed

3 the document but indicated—including by writing on the updated PIP—that she disagreed with Nieves’s assessment. ECF No. 32-3 at 18; ECF No. 32-4 at 59–62. After reviewing either the initial or the updated PIP with Liu, Nieves told Liu to resign or be demoted. ECF No. 32-3 at 13. Liu responded that she saw no reason to be demoted and that

she would not resign. Id. On October 1, 2019, KCI terminated Liu. ECF No. 32-4 at 4. According to KCI, it terminated her because of (1) her “disagreement with every part of the follow-up PIP” and (2) “her minimal to no improvement shown.” Id. After Nieves told Liu she was fired, Liu gave Nieves a complaint she had written a few days prior. ECF No. 32-3 at 17.3 In this complaint, Liu asserted that Nieves had retaliated against her based on an assumption that Liu was the author of an anonymous survey response critical of Nieves. See ECF No. 32-4 at 66. On October 3 and 7, 2019, Liu emailed KCI officials reiterating this assertion and arguing that Nieves had fabricated the complaints about Liu’s work. See ECF No. 32-4 64–80.

III. Alleged Incidents of Discrimination Liu points to several incidents she argues demonstrate that she was subject to discrimination at KCI based on her Chinese national origin.4 Liu heard coworkers at KCI direct the word “chinglish” towards her “many times.” ECF No. 32-3 at 25. She identifies two specific occasions, both of which involved Nieves. On the first, Liu was meeting with Nieves one-on-one when Nieves allegedly got mad and said, “you

3 Liu claims in her Response that she delivered the complaint before her termination. See ECF No. 37 at 35. But she points to no evidence of that, while Defendants point to Liu’s own testimony that she gave the complaint to Nieves after she was fired. ECF No. 32-2 at 16–17. 4 The relative timing of these events is not entirely clear. 4 chinglish.” ECF No. 32-3 at 19. On the second, Nieves asked Liu to write something that Liu believed federal regulations prohibited her from writing. Id. Liu refused, and Nieves accused her of disobedience. Id.
