Thank you for your loyalty and dedication over the past eight-plus years, and for taking the time to share your feedback. We are glad to hear that you find our compensation, benefits, and colleagues to be strong points of your experience. We also hear your concerns about the pace and impact of organizational change. We want to be transparent: as a global company, we operate in a rapidly shifting market environment, which means we must continuously evaluate and adapt our structure and operations. As a largely family owned company, we strive to make these transitions as thoughtful and targeted as possible. We recognize that change — particularly when it affects teams and roles — can feel disruptive, and we appreciate your honest reflection on this. Your advice regarding consistency in leadership and job expectations within the sales organization is well noted. We encourage you to bring these proposals forward through our annual Employee Engagement Survey, which is the dedicated channel for raising constructive suggestions that help shape the way we work and grow together. Thank you once again for your continued commitment to MilliporeSigma.

Pros

Decent hourly pay coupled with shift differential. Great opportunity to work with large scale and small scale production within a GMP facility.

Cons

Zero support and supervisor oversight for weekend shifts and night shifts. Bare minimum PPE for the level of toxic materials and solvents used in everyday production. Extremely toxic work environment both in the labs and interpersonally within the team. Prepare for your physical and mental health to take a major hit. High burnout and turnover rate over the last few months due to lack of oversight and increasing tolerance of inappropriate workplace behaviors.

The concerns you have raised are serious, and we do not take them lightly. We want to be clear: a safe working environment — both physically and interpersonally — is a standard we hold ourselves to without exception, and any perception that this has fallen short requires our full attention. While we are unable to speak to the specifics of your experience, we want to assure you that these concerns will be taken seriously and reviewed accordingly. We would also encourage anyone who has experienced or witnessed similar concerns to report them through our SpeakUp Line, which allows for confidential reporting: www.bkms-system.net/ISPEAKUP We also appreciate your recognition of the hourly pay, shift differential, and the valuable experience working within our GMP facility — these reflect our genuine commitment to offering meaningful opportunities to our team members.

Thank you very much for your review! Flexible working and the ability to work remotely are things we've invested in thoughtfully, so it's genuinely pleasing to hear they are having a positive impact on your day-to-day experience. On internal mobility: the reality of operating at our scale is that processes can sometimes feel slower or more rigid than we'd like — and we know that can be frustrating for talented people looking to grow and move. We recently introduced MyGrowth to address this challenge, however this is an area worth raising through our annual Employee Engagement Survey, where concrete feedback from employees like you directly informs how we look to improve. Thank you for your review and for being part of the MilliporeSigma team.
