Pros

Lots of PTO once you earn tenure (18 days to start, 23 at 5 years, 26 at 10).

Cons

Senior leadership has had a full turn over and everyone is scared to say anything. The only way for groups to get more headcount is for current FTEs to work crazy overtime to demonstrate the ‘need’.

Pros

Better than average salary. Good PTO.

Cons

Senior Management is fearful, ineffective and ill-equipped for their roles. Every senior leader comes from questionable backgrounds either in lack of experience or meaningful past success. Absolutely do not practice what they preach. Discuss "safe environment", "no retaliation", "do well, by doing good". All meaningless slogans. HR is there going through the motions. Retaliation is common. People are afraid to offer honest assessments. DO NOT tell management anything other than everything is great and they're the best. As company has grown, every meaningful benefit has gotten worse. Equity grants have shrunk to the point that it really isn't a retention tool, particularly with the deep decline in value due to mismanagement of their ophthalmology and oncology franchises. Company would be in dire straits without Dupixent franchise, which has likely peaked.
