      Pros

      Pay and bonuses under Millipore were excellent, pay has stayed largely the same under Merck, bonus formula is different and not as high, but still good.

      Cons

      Extreme stress, chaos, no work/life balance is destroying the best workers (the worst never did anything before and don't now and probably don't even realize the company was sold). Ludicrous number of projects all deemed "mission critical" all going on at the same time, using subsets of the same workers and managers so that the best and the brightest are massively overcommitted. Process is a bunch of forms to fill out, but there is no day-to-day process and whenever someone tries to institute one, it gets torpedoed by management. The best workers are burned out to the point of exhaustion and have mostly given up or have already left the company to be replaced with a revolving cast of contractors. This is across MIS and beyond into the rest of the company.

      Pros

      Some managers were exceptional mentors and played a significant role in my professional growth. Good benefits and a reasonable severance package during workforce reductions. Opportunities to work on large-scale marketing initiatives and collaborate with experience professionals across the organization and globe.

      Cons

      Advancement opportunities often felt inconsistent and lacked any transparency. Leadership frequently emphasized data-driven decision making, but business decisions did not always appear to align with the metrics being presented. The company appeared hesitant to embrace emerging technologies and AI-driven approaches, limiting innovation in multiple areas. Job security is uncertain, and organizational changes occur frequently with little warning. Management quality varied significantly, While some leaders were outstanding, others struggled with communication, strategic direction, and people management. Career growth seemed to depend heavily on organizational politics and alignment with leadership rather than solely on measurable performance.
