Pros
Excellent science, groundbreaking medicines. Workers who care and are passionate about their jobs.
Cons
Massive amounts of uncertainty. Especially poor communication style of current CEO- who supposedly strives for transparency, but never really says anything except drops hints and causes massive amounts of unrest. Also, some concern about putting all eggs in one basket... and about whether they can stick to decisions made. Some high level management have very poor leadership skills, frenzied strategic vision, and even sketchy, blatant nepotism and favoritism. They say they care about career development but in many ares this seems HR lip service rather than truth. Especially as the close very productive sites and do virtually nothing for the people left behind.
