Pros
Work from home opportunities (if you are disciplined enough to actually do work while at home), good facilities (new state-of-the-art cafe, coffee bar, work spaces, etc.), decent pay and benefits.
Cons
If you are someone that is looking to feel good about the work you are doing, get a sense of accomplishment, wants to be rewarded for that work - then Cigna is not for you. Politics, process, protocol, personalities all get in the way of actually doing anything. Meetings to discuss when to have more meetings. Conference calls all day with people working from home (with dogs barking, children yelling in the background) which yields nothing valuable. You could work here 20 years if you can be a button pusher and accept the "no" culture that has been established. (Many do.) Internal turnover is high. Good managers figure it out quickly and move on. What's left are the lazy and unmotivated.
