      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.

      Business outlook

      Pros

      Some managers were exceptional mentors and played a significant role in my professional growth. Good benefits and a reasonable severance package during workforce reductions. Opportunities to work on large-scale marketing initiatives and collaborate with experience professionals across the organization and globe.

      Cons

      Advancement opportunities often felt inconsistent and lacked any transparency. Leadership frequently emphasized data-driven decision making, but business decisions did not always appear to align with the metrics being presented. The company appeared hesitant to embrace emerging technologies and AI-driven approaches, limiting innovation in multiple areas. Job security is uncertain, and organizational changes occur frequently with little warning. Management quality varied significantly, While some leaders were outstanding, others struggled with communication, strategic direction, and people management. Career growth seemed to depend heavily on organizational politics and alignment with leadership rather than solely on measurable performance.
