v. : Civil Action No. DKC 25-2299

: CHARLES RIVER LABORATORIES, INC., et al. :

MEMORANDUM OPINION Presently pending and ready for resolution in this employment case alleging sex and national origin discrimination are the motion to dismiss or, in the alternative, for summary judgment filed by Defendant Robert F. Kennedy, Jr., Secretary, U.S. Department of Health and Human Services (“Defendant”), (ECF No. 36); the motion for leave to file limited surreply filed by Plaintiff Mykola Yuzhakov (“Mr. Yuzhakov” or “Plaintiff”), (ECF No. 49); and the motion for leave to file supplemental memorandum and notice of supplemental authority in support of surreply filed by Mr. Yuzhakov, (ECF No. 51). The issues have been briefed, and the court now rules, no hearing being deemed necessary. Local Rule 105.6. For the following reasons, the motion to dismiss or, in the alternative, for summary judgment will be granted in part and denied in part, and both motions filed by Mr. Yuzhakov will be denied. I. Background A. Factual Background1 Mykola Yuzhakov is a young Ukrainian man who arrived in the United States in October 2022 after fleeing the ongoing war between Russia and Ukraine. (ECF No. 1 ¶ 5). After arriving in the United

States, Mr. Yuzhakov was granted Temporary Protected Status (“TPS”). (Id.). He decided to reside in Maryland and seek employment here. (See id. ¶¶ 5, 7). On April 29, 2024, Mr. Yuzhakov obtained employment as a veterinary laboratory technician with Charles River Laboratories (“CRL”), a “global scientific research organization that assists government agencies and private companies in animal research and matters related to drug development and disease research.” (Id. ¶¶ 6–7). One of CRL’s federal contracts was with the National Institute of Allergy and Infectious Diseases (“NIAID”). (Id. ¶ 8). NIAID is a component agency of the National Institutes of

1 The facts herein are as alleged in the complaint. The paragraphs in the complaint are misnumbered. On page 24, after Paragraph 94, the paragraph numbering restarts at 51. (ECF No. 1, at 24). The complaint then proceeds with Paragraphs 51, 52, 53, and so forth, until it ends at Paragraph 73. In other words, there are two sets of Paragraphs 51–73, each with different allegations. All citations to Paragraphs 51–73 are to the first, correctly numbered set of such paragraphs. Any citations to allegations in the second, incorrectly numbered set are to the page numbers on which the allegations appear, rather than the paragraph numbers. 2 Health (“NIH”), which is housed within the U.S. Department of Health and Human Services (“HHS”). (Id. ¶¶ 10–11). Under that contract, CRL assigned Mr. Yuzhakov to work at a NIAID research

facility in Rockville, Maryland, where he would be “involved in animal studies on laboratory mice.” (Id. ¶¶ 7, 12). Mr. Yuzhakov would work at the Rockville facility “alongside CRL’s federal contract employees and under the oversight of a designated facility [v]eterinarian,” NIAID federal employee Dr. Julie Holdridge Nichols (“Dr. Holdridge”). (Id. ¶ 7). Dr. Holdridge “was the client representative for CRL’s federal contract.” (Id. ¶ 13). Although Mr. Yuzhakov would “primarily receive[] his work assignments from CRL supervisors,” he would also “receive[] frequent directions from Holdridge.” (Id.). At the heart of this case is the nature of the relationship that developed between Mr. Yuzhakov and Dr. Holdridge. More to

the point, Mr. Yuzhakov identifies a series of interactions that he believes demonstrate inappropriate, sexualized behavior by Dr. Holdridge. On Mr. Yuzhakov’s first day at the NIAID facility, Dr. Holdridge greeted him at the door and introduced herself as “Julie.” (Id. ¶ 19). According to Mr. Yuzhakov, Dr. Holdridge never requested that he refer to her by her formal title. (Id.). 3 Before Mr. Yuzhakov received badge access to the facility, Dr. Holdridge continued to open the door for him daily, sometimes “intercepting other staff members” to do so. (Id. ¶ 20). She

once told him: “Looks like you need rescuing—come on in, you’re with me now.” (Id.). Mr. Yuzhakov viewed these actions as “friendly” and “welcoming.” (Id.). From the first veterinary round Mr. Yuzhakov participated in, however, he notes conduct by Dr. Holdridge that he deemed intimate and “unwelcome.” (Id. ¶ 21). During Mr. Yuzhakov’s first veterinary round, Dr. Holdridge “leaned in to smell [his] cologne, drawing the scent from his chest and commenting, ‘I like it.’” (Id.). When they proceeded to the next room in the round, Dr. Holdridge bent over to reach the shoe covers; in doing so, she “pressed her buttocks into [Mr. Yuzhakov’s] groin area.” (Id. ¶ 22). He “stepped back, startled by the unwelcome touching”; she then turned around, apologized, and put on her shoe cover. (Id.).

On another one of Mr. Yuzhakov’s early rounds, he and Dr. Holdridge noticed that Malcolm Vaughan, then the Assistant Facility Manager, appeared to be “monitoring” them and “keeping an eye on their interactions.” (Id. ¶ 23). After Dr. Holdridge asked Mr. Vaughan where he was going next, she told him that they had already been there. (Id. ¶ 24). Once he had left, Dr. Holdridge 4 told Mr. Yuzhakov: “He’s gone—we don’t need him keeping tabs on us.” (Id. ¶ 25). Although it was allegedly “standard practice” for veterinary

technicians like Mr. Yuzhakov to rotate every three months to a different laboratory room, Mr. Yuzhakov did not rotate. (Id. ¶ 38). Dr. Holdridge asked him “if he liked Room 516B and he said yes”; thereafter, “she ensured he remained there.” (Id. ¶ 39). When he asked her whether he would rotate, she replied: “No, honey, I’m not going to allow them to do that.” (Id. ¶ 40). Mr. Yuzhakov alleges that Room 516B “became a space where [she] could frequently isolate [him] and engage in flirtatious behavior,” “make physical contact . . . such as massaging [Mr. Yuzhakov’s] back and shoulders,” and “discuss her personal life” out of view of others. (Id.). Unlike her practice with other veterinary technicians of using a wheeled writing stand to document observations, Dr.

Holdridge “would hand [Mr. Yuzhakov] the clinical record book and position herself so that her forearm and torso pressed against [his] midsection while she wrote.” (Id. ¶ 41). And whenever she entered Room 516B, Dr. Holdridge would insist on wearing Mr. Yuzhakov’s lab coat, even if another one was available. (Id. ¶ 50). She would make comments such as “Your lab coat is the only one that fits me just right” and “I always know which one is yours— 5 it smells like you.” (Id.). Mr. Yuzhakov never observed Dr. Holdridge wearing the lab coat of any other staff member. (Id. ¶ 51). When CRL brought in new lab coats, Dr. Holdridge remarked that they “were very blue just ‘like my eyes.’” (Id. ¶ 52). Mr.

Yuzhakov replied: “Yes, your eyes are blue like this lab coat.” (Id.). One afternoon in mid-2024, Dr. Holdridge requested Mr. Yuzhakov’s assistance in Room 516B. (Id. ¶¶ 26–27). There, she brought out some ointment to be applied to the animals. (Id. ¶ 28). But “instead of handing it to [Mr. Yuzhakov] or applying it directly to the animals as procedure would dictate, she placed it on her own fingertip and slowly transferred it onto [his] finger” two times. (Id.). He characterizes the “gesture [as] slow, lingering, and unmistakably personal.” (Id.). She then sat down on the floor and “gestured for [Mr. Yuzhakov] to squat down next
