We appreciate you highlighting the strength of our benefits package and your positive impression of our new CEO. Your feedback on the return-to-office push is also noted. MilliporeSigma aims to balance flexibility with collaboration needs and the requirements of different roles and sites, and we know this can feel different across teams. Please continue to share input through your manager, HR partners, and our Employee Engagement Survey so we can refine how we support effective ways of working. Thank you for your continued commitment and for taking the time to leave a review.

It is great to read that you experience MilliporeSigma as a positive environment with opportunities to grow, especially when you actively engage. We also recognize your point that, in a large organization like ours, building close peer relationships can take more intention and support. Many teams rely on structured onboarding, cross-functional projects, and site or community networks to help people connect beyond their immediate group. If you have ideas on what would make it easier in your area, please share them with your manager or through our Employee Engagement Survey (EES) so we can strengthen collaboration and belonging.

Thank you for taking the time to share your perspective. We are pleased that you experience MilliporeSigma as supportive and that the benefits and schedule are working well for you. Your point about messages from Corporate not always translating consistently at the site level is an important one. Clear, aligned communication and strong local context are essential for trust and effective execution. We continue to strengthen how information is cascaded and how feedback from sites is incorporated, and we encourage you to share specific examples through your manager or via the Employee Engagement Survey (EES) so local and functional leaders can address gaps.
