The Cigna Group reviews

Multi-national, very large company, bureacratic salary/bonus reviews; too much dependence on Dept performance, not individual performance. Lots of employees stay there for the stability, not because they are good at their jobs (ie "Lifers"). Salary ranges for each "band" or grade level are not communicated (makes setting goals difficult).

If you're already employed, dont expect to get a salary raise as a result of an MBA. Once you're in a box at Cigna, it's hard to break the mold. Management tends to pick a very few and put them on the desired path, regardless of whether or not you're capable of doing the same. It's a running joke that the best way to get a good raise or shift departments is to leave Cigna, then return a few years later.
