If you want to be miserable, work for Genzyme - Manufacturing Associate Sanofi Employee Review

Good benefits (9% 401k match, company car, solid insurance). Huge company with many therapeutic areas you can choose from. I like my coworkers.

Employee stock purchase plan is nice in theory, but stock has treaded water for many years. A very big company with lots of big pharma metrics to meet. Pay is maybe slightly below industry average.

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

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.
