IN THE UNITED STATES DISTRICT COURT FOR THE WESTERN DISTRICT OF PENNSYLVANIA

SUZANNE SULLIVAN, ) ) Plaintiff, ) ) 2:22-cv-00116 v. ) ) EXACT SCIENCES CORPORATION, et ) al., ) ) Defendants. ) OPINION Mark R. Hornak, United States District Judge During one of the deadliest pandemics in history, medical professionals moved quickly to produce a vaccine against the novel coronavirus, commonly known as COVID-19. With innovative mRNA technology, scientists believed they could create a vaccine using only the virus’s genetic sequence, instead of using a weakened form of the physical virus. This plan would bypass the slow and complex process of growing live viruses in labs, thus putting a COVID-19 vaccine out for public administration much faster than usual. It worked. COVID-19 vaccines were developed at an unprecedented pace, becoming widely available less than a full year after the virus’s genetic sequencing. While tens of millions received the mRNA vaccine without concern, this record-breaking time of development gave some others pause. For these individuals, the speed at which the COVID-19 vaccines were created raised concerns of safety and efficacy. These concerns were only heightened in an environment where COVID-19 and the public and medical response to it had become a widespread political issue. For some, it was not off base during this time to be cautious about receiving a medical injection that was made quickly using an innovative vaccination technology, especially when even the most discerning listener did not have to look far to find various commentators, scientific or otherwise, questioning its legitimacy. For others, the vaccine’s arrival generated confidence in their ability to safely return to daily activities unimpeded by more complicated COVID-19 precautions and concerns. But there was still a pandemic going on, and for many, remaining unvaccinated was seen

as posing risks for themselves and those around them. For many employers whose employees could work remotely — performing most if not all of their job’s functions safely and essentially alone at home — this was not an issue. For others, working face-to-face was central to the job. Some employers in this latter category saw that requiring vaccination for their employees could greatly reduce the risk of COVID-19 transmission on the job while allowing the course of business activities to resume and proceed. These employers began to require vaccination for any position involving face-to-face interaction. This at times caused friction when such requirements rubbed up against the vaccine skepticism some employees harbored. And this friction had the capacity to fuel workplace passions, leading to disputes, confrontations, and even employment terminations when the employer’s directives collided with the views and concerns of involved employees.

That narrative in some ways lays down the background for this case. But to be clear, to decide the matters now front and center in this case in the Defendants’ Motion for Summary Judgment, the Court need not resolve those broader competing public and personal interests, nor is it charged with assessing the wisdom of the workplace vaccination policies involved here or the perception of employees about them. The issues presently before the Court are more constrained and instead require the Court to consider whether the decisions in play here could be found by a rational jury to violate federal and state statutes addressing disability discrimination in the workplace and providing for workplace leave. Suzanne Sullivan (“Plaintiff” or “Ms. Sullivan”) worked as a Professional Medical Representative for Exact Sciences Corporation (“Exact”), selling cancer screening technology to health care providers. Because these sales occurred face-to-face, there came a time when Exact required all employees in Ms. Sullivan’s position to receive the COVID-19 vaccine to remain in

their job. Ms. Sullivan was skeptical of the safety and efficacy of the COVID-19 vaccine, and she and at least one other co-worker had expressed this skepticism to Exact’s upper management. Central to the issues in resolving the pending Motion, she also had previously experienced complications with influenza vaccine injections, and she requested a temporary exception from her employer’s vaccine requirement to undergo medical testing to ensure the COVID-19 vaccine would be safe for her. Her request was eventually denied after some time and several general extensions to Exact’s vaccination timetable, and she choose employment termination over receiving the COVID-19 vaccine or applying to fill another role within her employer. Now Ms. Sullivan brings this lawsuit against Exact (her employer), and its Chief Executive Officer Kevin Conroy. In her Amended Complaint, Ms. Sullivan alleges disability discrimination,

unlawful retaliation, and violations of her rights under the Americans with Disabilities Act (“ADA”), the Pennsylvania Human Relations Act (“PHRA”), and the federal Family Medical Leave Act (“FMLA”). (ECF No. 22). Defendants have filed a Motion for Summary Judgment. (ECF No. 72). The Motion has been fully briefed, (ECF Nos. 81, 86), the Court has heard Oral Argument on the parties’ positions, (ECF No. 99), and the parties have had the chance to file Supplemental Memoranda as directed by the Court relative to issues the Court identified as being tied into the arguments of the parties, (ECF Nos. 102, 103, 107, 108). For the reasons that follow, Defendants’ Motion for Summary Judgement will be GRANTED IN PART and DENIED IN PART. BACKGROUND Ms. Sullivan began working for Exact in late 2019, a few months before the spread of COVID-19 was declared a pandemic, as a Professional Medical Representative (“PMR”), promoting the benefits of using Exact’s cancer screening technology to health care providers. (ECF

No. 80 ¶¶ 7, 8). Ms. Sullivan made her sales pitches face-to-face with providers in their facilities, sometimes even in their offices. (ECF No. 80 ¶ 11). Ms. Sullivan typically saw between six and ten providers a day, and had a company-assigned goal to visit around 40 providers per week. (ECF No. 80 ¶¶ 9, 10). Then, the pandemic. As COVID-19 spread rapidly across the country in early 2020 Exact pulled its PMRs from the field. After public understanding of COVID-19’s transmission mechanism improved, Exact redeployed its PMRs in late June 2020 with certain safety policies in place. (ECF No. 80 ¶ 15). These policies mandated masking, testing, and social distancing. PMRs were required to always maintain a safe distance from others while working and to wear a face mask when interacting with providers. (ECF No. 75-1 at 90:23-91:5). PMRs were also required to

take a COVID-19 test every fourteen days. (ECF No. 82-19 at 5). Exact announced its COVID-19 vaccination policy on July 30, 2021. (ECF No. 80 ¶ 16). COVID-19 vaccines were by then widely available, and CEO Kevin Conroy announced that any Exact employee whose job included in-person work would need to be fully vaccinated by September 15, 2021. (ECF No. 80 ¶ 16). This deadline was later extended to October 1, 2021. (ECF No. 80 ¶ 17). Mr. Conroy also announced a process for employees to request accommodations and exemptions from this policy for qualifying medical and religious reasons. Employees making such requests were often offered an accommodation in the form of the opportunity to apply for an alternative role in the company and were given preference for placement in such roles during the application process. (ECF No. 80 ¶¶ 22, 24). Notably, this was not a guarantee of placement in another role. Ms. Sullivan did not want to receive the COVID-19 vaccine. She was concerned that the vaccines were unsafe and that they had not undergone adequate testing during their development
