Pros
You have access to lots of thought around best practices and technical information. As a data junkie I enjoy this most in working for Marsh. We have experts in lots of subject areas and have the best resources to offer clients. People work hard and I haven't encountered the ethical problems or political b.s. I've seen in other workplaces (the NY situation was in no way indicative of the overall culture).
Kontras
Cumbersome time-consuming procedures that predate transparency, remote management (NY can't help but be out of touch with local needs), no agency management system and lots of wholesale changes of systems with no conversion of data or thought of how much time the new procedure/system will take. The training is catch as catch can unless you're a new college grad but a mentoring program is being put into place. When people leave they are never replaced in a timely manner.
