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.

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.

Thank you for sharing your experience — we recognize that leaving this review takes courage, and we want you to know that your feedback is taken seriously. We are glad that you take pride in the company's global reputation, and we appreciate your continued commitment to MilliporeSigma. However, we are deeply concerned by the issues you have raised. A biased, toxic, or discriminatory work environment is fundamentally incompatible with our values and with the kind of company we are committed to being. Allegations of racism, in any form, are never acceptable and are not reflective of the culture we strive to build and maintain. We strongly encourage you to report your experiences through our SpeakUp Hotline, which allows for anonymous reporting: www.bkms-system.net/ISPEAKUP. These channels exist precisely to ensure that every employee feels safe, heard, and protected — and that issues are addressed with the seriousness they deserve. Thank you again for speaking up. We encourage you to continue contributing to our company while also making use of the resources available to you, because every employee deserves to work in an environment built on respect and fairness.
