Merck Employee Alleged Bias After Performance Downgrade
A recent complaint highlights how performance review processes can create significant legal and internal friction.
Updated on Oct. 12, 2026 in Human Resources

In an August 2024 resolution, Merck closed an internal investigation into allegations of a multi-year discriminatory campaign against an employee. The case centers on performance-based disciplinary actions that followed the worker's pregnancy announcement.
Why it matters
For managers, the case underscores the operational risks inherent in documenting subjective behavioral events, such as attendance at optional social functions, as formal performance concerns. When these actions coincide with protected status disclosures, they invite scrutiny into whether documentation serves as a legitimate performance tool or a retaliatory mechanism.
The worker was required to fly between North Carolina and New Jersey 15 times between May and November 2023, while facing performance reviews that cited missed social events. The review process occurred within a three-level grading scale that resulted in a halved bonus.
The players
Merck
A global pharmaceutical company with corporate operations in New Jersey that develops, manufactures, and markets medicines and vaccines.
The details
The dispute centers on whether a supervisor weaponized performance evaluations to pressure an employee after she announced her pregnancy. The supervisor documented a missed casino poker dinner at a December 2023 conference as a performance concern, leading to a Needs Improvement rating in early 2024. The complaint alleges this assessment ignored 20 favorable peer reviews and seven prior positive assessments, culminating in a significant bonus reduction.
Timeline
May to November 2023: The employee traveled between states approximately 15 times.
December 2023: The worker missed a poker dinner during a professional conference.
Early 2024: The supervisor issued a reduced bonus and a negative performance rating.
March 8, 2024: The employee filed a formal report of religious discrimination with HR.
August 2024: Merck closed the internal investigation with no findings of discrimination.
Market Landscape
This dispute reflects an ongoing trend where internal performance management systems are scrutinized under the Pregnancy Discrimination Act. It highlights the tension between subjective management assessments and the rigorous documentation required to defend against discrimination claims.
Operators should review their performance evaluation policies to ensure all criteria are strictly job-related and objective. When documenting performance deficiencies, maintain a clear distinction between core business outcomes and participation in discretionary social or networking events.
The takeaway
Management should audit their review processes to ensure that performance feedback focuses on quantifiable metrics rather than subjective attendance at non-mandatory social events. Establish a clear paper trail for all compensation adjustments to defend against future internal or external claims.
