Pros

Good pay. Great target bonus to off set that the company doesn't grant equity. Excellent retirement contributions. Flexible time off.

Cons

Dysfunctional organization. People have worked there for 15+ years and don't know the basics of drug development. It was astonishing. Basic GCP and or drug development terminology was foreign to people. You could work there for years and just coast under the radar not learning a thing. There's no growth mindset among employees. Feels more like govt than an industry. There are employees in the same exact role and level for 10+ years. So experience in the organization is lacking. They are stuck doing things that have been outdated in the industry. And no one takes ownership. It's disturbing to see just how little you need to know to get by and no one will question it. If something goes wrong just blame the cro and the chaos within the organization continues.

Bad leadership, declining culture, no work-life balance

Pros

Good benefits, competitive salaries, strong 401(k) match. PTO used to be generous before it was changed to "unlimited".

Cons

After significant leadership changes, the culture declined sharply. Employees are afraid to speak up because of retaliation. HR fails to protect employees. The culture shifted to the culture of fear and mistrust. The shift to “unlimited PTO” significantly worsened work-life balance. Time off depends heavily on manager approval, often discouraged even when requested far in advance, and unused time cannot be banked. Many employees experienced this change as negative despite how it was presented. A common theme shared by many who have left is poor leadership, no work-life balance, and expectations to be available 24/7 with little recognition. There is as clear gap between stated values and actual reality.
