Pros

Good boss (this seems to be rare) Autonomy Responsibility Given my role as an intern, I was almost left to work independently which was a big plus, since I think this is rare.

Cons

Poor company culture Lots of attrition Working in the Allston Landing Facility, I noticed that there were people leaving every week -- just from our department alone. Many co-workers expressed frustration with Genzyme culture, and the lack of support and empathy from upper management towards retention and development of staff.

Pros

The company has an excellent, very collegial atmosphere. Employees are supported well and there is excellent support for most processes from numerous line functions.

Cons

Some processes as well as the governance structure can be a bit confusing. More so than other large pharma companies. But even with this. There are almost always enough people who know how to get things done.
