Job Security

Job security is relatively strong compared with smaller biotech firms. There will be times when strategic reorganizations occur, and those can affect roles across the company. However, the company’s large portfolio and global footprint provide a buffer. Employees in critical R&D, regulatory affairs, and commercial roles often have higher stability. Job security will still depend on performance, business priorities, and shifts in therapeutic focus.

Senior leadership communicates strategic priorities clearly and places emphasis on compliance and patient outcomes. There is a formal structure for decision-making, and leaders will expect adherence to regulatory standards. Leadership sets ambitious goals and supports investments in research and manufacturing capabilities. There will be variability in how middle management translates strategy into day-to-day operations; some teams will experience strong, visible leadership while others may feel more distant.

Manager Reviews

Managers tend to be competent and technically knowledgeable. Many are committed to employee development and mentorship. Feedback from staff indicates that manager quality can be inconsistent: some managers excel at coaching and career planning, while others emphasize short-term deliverables. Performance reviews are generally structured and tied to measurable objectives. If you want a good manager, do your research during interviews and ask about team leadership style.

Remote Work Support

Remote work support is robust for roles that are not laboratory- or manufacturing-based. Many corporate functions operate in hybrid models, with flexibility for remote days. For lab, clinical, and manufacturing staff, remote options are limited due to the nature of the work. The company provides tools and policies to support distributed teams when appropriate.

Average Working Hours

Typical working hours are about 40 hours per week for many corporate roles. Project deadlines, trials, and launches can push hours into the 45–60 hour range temporarily. Laboratory and manufacturing shifts may follow different schedules, including nights or weekends as needed.

Attrition Rate & Layoff History

Attrition is generally lower than many small biotech peers, but some departments experience higher turnover depending on project cycles. The company has enacted targeted layoffs or restructures in the past as part of strategic shifts; these were typically related to pipeline priorities or business realignments rather than broad, repeated downsizing.

Overall Company Rating

Overall, the company is rated well for stability, mission-driven work, and comprehensive benefits. Employees value the scientific rigor and global reach. There will be trade-offs: the environment is structured and compliance-focused, which suits many but may feel bureaucratic to those seeking a fast-moving startup vibe. If you are evaluating working at Merck & Co., consider the role and team carefully — the company offers strong resources and career pathways, particularly for those committed to long-term impact in healthcare.
