Pros
I started at Chubb 5 years ago, right out of college. Chubb has a great name that the company does it best to stand behind. Profit sharing and merit based raises are a definite plus. Prior to the merger, there were a great deal of programs centered on helping employees better themselves for career advancement and broaden their knowledge of the company and insurance in general.
Cons
Depending on your department/manager work life balance is either supported or looked down upon. I had some major health issues during a recent pregnancy. Now that I am back at work, I feel like I am being penalized and singled out because of that. So far, the merger seems to have made the company more information based. Prior to merger, Chubb was more people/employee focused.
