Pros
The focus on science, the passion of the scientist. The desire to really try to stem human suffering with advancements in science. Merck has a long history of pharma development and the current CEO is focused on early drug development. I cannot stress how dedicated the scientist here are.
Cons
Upper management should be ashamed of themselves. The lack of communication is appauling. The constant "we don't know yet" or "we are still working that out" sows not only confusion but uncertainty. The lack of promotions...I could go on about this for pages but I'll leave is with "don't expect one" the refrain that I have heard for years is always the same, there is always some reason why they can't or more likely won't. Even when the company does better that expected things are still "right right now." I may sound disgruntled but I actually love working at Merck...it's just frustrating...very frustrating having to deal with upper management.
