Vantaggi
They have a reasonably complete benefits package: 401(k), DB plan, health, employer term life insurance, etc. Rank and file employees are extremely hard-working for the most part and they tend to believe strongly in what they are doing. There is a stated valuing of diversity and some efforts to put that into place.
Svantaggi
Management down to the business-line management level seems to be misguided or uncertain. Stated recognition of employee individual contributions is contradicted by a fill-a-slot reorganization mania in the past 5 years. Investment in infrastructure has not been adequate, though I hear that this is the case with most US companies. I also think that they business line management allows itself to be controlled by outside interests too much.
