Pros

This is a short list: free fruit Tuesdays and breakfast on Thursdays. Free beverages. Friendly and talented coworkers.

Cons

Highly inept and out-of-touch middle management. Most are clueless and rely on intellectually superior and/or more experienced subordinates. Theoretically there are standards for career development and advancement, but those are hardly applied in practice. Promotions are 20% hard work, 80% who u know and kiss up to. Corporate structure is an upside-down triangle: lots of scientists/managers are perm hired, but few RA positions. Many of those RA positions are temp hired, so a lot of training is invested only to see them either quit or let go due budgetary concerns. Initiatives, particular for improving employee morale or communications are unfortunately half-baked. Initially hyped with the usual buzzwords, these initiatives typically fall to the wayside and become forgotten.

Advice to Senior Management

Upper management is out-of-touch with reality. They set lofty goals but don't back it up with the necessary supporting staff. You can't rely on the revolving corps of low level temps, nor the hiring of upper level employees to accomplish these goals.
