Pros
There are very good, experienced people in the R&D teams who will teach and mentor others. These people are both from within GSK (help you navigate the politics and silos of a huge organization) and outside (bring new expertise and insights on improvements).
Cons
GSK has done a major re-organization of R&D, changing structures of both systems and the organization at the same time. Outside people have been brought in to lead organization and these people have little connection to the reality of the day-to-day tasks that need to be done and the time it takes. Leadership is clearly driven by revenue, and what commercial says, goes, even if they have little insights into the issues at hand. Many senior experienced team members have thrown up their arms and left due to lack of respect, transparency and resources to do their job. Change brings opportunity, right?Only if you can hang on long enough!
