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.

Pros

Great benefits, there’s flexibility when you need it, and the’s a significant amount of PTO. There is a lot of growth and development opportunities, as in learning new skills or strengthening skills.

Cons

There is a lot of restructuring happening, which often results in teams having to do the work of many without being compensated appropriately. This results in longer days, burn out, and feeling undervalued. There is a lot of encouragement for growth, but the actual growth/promotion part doesn’t seem to happen from leadership side. There is a lot of room for process improvements but too many teams work in silos and don’t want to work together so processes don’t get improved.

Thank you for sharing your experience, and for your continued commitment to MilliporeSigma over more than three years. We are glad that the benefits, flexibility, PTO, and learning opportunities have been meaningful to you. We are sorry that recent changes have affected your day-to-day experience. As a company with a long-term perspective and a strong sense of responsibility towards our people, organizational changes are never taken lightly. We are mindful that the impact on workload and team dynamics can feel significant at an individual level, and we understand that the experience on the ground does not always reflect the full picture of what those decisions are intended to achieve. Your points about career development follow-through and cross-team collaboration are noted, and we continue to work on improving how we support employees through change, how we deliver on development commitments, and how we enable better ways of working across teams. As a current employee, we would encourage you to share your experience through our Employee Engagement Survey, as your input directly helps shape the priorities we focus on.
