Fragile Leadership

Anonymous employee

Pros

-Good work/life balance that is respected and supported. -Flexibility with WFH if needed. -Desire to grow is encouraged.

Cons

-No sense of solid and consistent leadership. Since 2020, leadership on the Merck side has undergone a reorganization every few years. As a result, business areas have no consistent leadership. -As business areas are on the decline, Merck leaders rotate out as people get laid off. -When new leadership rotates in, they have to play a lot of catch up and learn what Millipore does in the U.S. This also changes future direction. -Leadership seems out-of-touch with what is exactly happening. -Compensation is below market value.

Thank you for sharing your feedback as a current employee at one of our Boston locations. We appreciate your honesty and are pleased to hear that you value the work-life balance, flexibility with remote work, and the encouragement to grow at MilliporeSigma, part of Merck KGaA, Darmstadt, Germany. In increasingly volatile markets, even comparatively stable companies like ours - also thanks to being largely family-owned, with a long-term view - sometimes need to adapt structures and leadership. Every reorganization can indeed create uncertainty and impact team continuity, and we always try to balance expected outcomes and impact. Your feedback about leadership accountability, market compensation, and the need for consistent direction is valuable input that helps us identify areas requiring attention. As a current employee, we encourage you to share these specific concerns through our annual Employee Engagement Survey, which provides a formal channel for raising improvement proposals and ensures your voice reaches senior decision-makers. We're committed to strengthening our leadership practices and maintaining consistent direction for our teams. Thank you for your continued dedication and for taking the time to provide this constructive feedback.

Thank you for taking the time to share your experience! It's great to hear that our 401K match, PTO, benefits and management left a positive impression. These are areas we invest in meaningfully, and it's rewarding to know they made a difference during your time with us. We also take note of your personal experience regarding dynamics in the workplace. A respectful and collaborative work environment is something we care deeply about, and we understand that navigating workplace relationships is not always straightforward. We continuously work to foster a culture where issues are handled constructively and fairly at all levels. Thank you again for your review, we wish you all the very best in your future endeavors.

Pros

Good benefits and all around workplace. When first hired, a tremendous effort was made to support employees and make you feel "at home".

Cons

As new upper management takes over, you notice the pros becoming less and less (e.g.). My out of pocket insurance costs, doubled, over the last year. I no longer notice the effort to make you feel "at home".
