Pros
Boulder county is not the biotech hot-spot that Massachusetts or California is and Amgen offers the most generous compensation and benefits packages that I have found in the area. I recently had to take a short medical leave and found my coworkers and management very supportive and seemingly genuinely concerned with my well-being.
Cons
Amgen management makes much of their openness to feedback and input from all levels of staff, all the while exhibiting a patronizing attitude toward staff and ignoring that same feedback and input. I feel disconnected from the decisions of management and the direction of the company. Inconsistencies in promotion and compensation decisions between groups has lead to resentments between coworkers, and an unwillingness to promote within my own group has lead to resentment against management.
